A call operation action is an action that transmits an operation call request to the target object, where it may cause the invocation of associated behavior. The argument values of the action are available to the execution of the invoked behavior.

A classifier is a classification of instances - it describes a set of instances that have features in common. A classifier can specify a generalization hierarchy by referencing its general classifiers.
A classifier has the capability to own use cases. Although the owning classifier typically represents the subject to which the owned use cases apply, this is not necessarily the case. In principle, the same use case can be applied to multiple subjects, as identified by the subject association role of a use case.
Classifier is defined to be a kind of templateable element so that a classifier can be parameterized. It is also defined to be a kind of parameterable element so that a classifier can be a formal template parameter.
A classifier has the capability to own collaboration uses. These collaboration uses link a collaboration with the classifier to give a description of the workings of the classifier.

A generalization is a taxonomic relationship between a more general classifier and a more specific classifier. Each instance of the specific classifier is also an indirect instance of the general classifier. Thus, the specific classifier inherits the features of the more general classifier.

When isCovering is true, every instance of a particular general Classifier is also an instance of at least one of its specific Classifiers for the GeneralizationSet. When isCovering is false, there are one or more instances of the particular general Classifier that are not instances of at least one of its specific Classifiers defined for the GeneralizationSet.

If isDisjoint is false, the specific Classifiers in a particular GeneralizationSet have one or more members in common; that is, their intersection is not empty. For example, Person could have two Generalization relationships, each with the different specific Classifier: Manager or Staff. This would be disjoint because every instance of Person must either be a Manager or Staff. In contrast, Person could have two Generalization relationships involving two specific (and non-covering) Classifiers: Sales Person and Manager. This GeneralizationSet would not be disjoint because there are instances of Person which can be a Sales Person and a Manager.

An information flow specifies that one or more information items circulates from its sources to its targets. Information flows require some kind of information channel for transmitting information items from the source to the destination. An information channel is represented in various ways depending on the nature of its sources and targets. It may be represented by connectors, links, associations, or even dependencies. For example, if the source and destination are parts in some composite structure such as a collaboration, then the information channel is likely to be represented by a connector between them. Or, if the source and target are objects (which are a kind of instance specification), they may be represented by a link that joins the two, and so on.
The sources and targets of the information flow can only be one of the following kind: Actor, Node, UseCase, Artifact, Class, Component, Port, Property, Interface, Package, ActivityNode, ActivityPartition and InstanceSpecification except when its classifier is a relationship (i.e. it represents a link).

Since an interface specifies conformance characteristics, it does not own detailed behavior specifications. Instead, interfaces may own a protocol state machine that specifies event sequences and pre/post conditions for the operations and receptions described by the interface.
Interfaces may include receptions (in addition to operations).

An interface specifies a contract; any instance of a classifier that realizes the interface must fulfill that contract. The obligations that may be associated with an interface are in the form of various kinds of constraints (such as pre- and post-conditions) or protocol specifications, which may impose ordering restrictions on interactions through the interface.

Package specializes TemplateableElement and PackageableElement specializes ParameterableElement to specify that a package can be used as a template and a PackageableElement as a template parameter.
A package is used to group elements, and provides a namespace for the grouped elements.
If an element that is owned by a package has visibility, it is public or private.
OCL

A port has an associated protocol state machine.
A port is a property of a classifier that specifies a distinct interaction point between that classifier and its environment or between the (behavior of the) classifier and its internal parts. Ports are connected to properties of the classifier by connectors through which requests can be made to invoke the behavioral features of a classifier. A Port may specify the services a classifier provides (offers) to its environment as well as the services that a classifier expects (requires) of its environment.

If true indicates that this port is used to provide the published functionality of a classifier; if false, this port is used to implement the classifier but is not part of the essential externally-visible functionality of the classifier and can, therefore, be altered or deleted along with the internal implementation of the classifier and other properties that are considered part of its implementation.

Property represents a declared state of one or more instances in terms of a named relationship to a value or values. When a property is an attribute of a classifier, the value or values are related to the instance of the classifier by being held in slots of the instance. When a property is an association end, the value or values are related to the instance or instances at the other end(s) of the association. The range of valid values represented by the property can be controlled by setting the property's type.
A property is a structural feature of a classifier that characterizes instances of the classifier. A property related by ownedAttribute to a classifier (other than an association) represents an attribute and might also represent an association end. It relates an instance of the class to a value or set of values of the type of the attribute. A property related by memberEnd or its specializations to an association represents an end of the association. The type of the property is the type of the end of the association.
A property has the capability of being a deployment target in a deployment relationship. This enables modeling the deployment to hierarchical nodes that have properties functioning as internal parts.
Property specializes ParameterableElement to specify that a property can be exposed as a formal template parameter, and provided as an actual parameter in a binding of a template.

Protocol state machines can be redefined into more specific protocol state machines, or into behavioral state machines. Protocol conformance declares that the specific protocol state machine specifies a protocol that conforms to the general state machine one, or that the specific behavioral state machine abide by the protocol of the general protocol state machine.
Specifies the protocol state machine to which the specific state machine conforms.
Specifies the state machine which conforms to the general state machine.
A protocol state machine is always defined in the context of a classifier. It specifies which operations of the classifier can be called in which state and under which condition, thus specifying the allowed call sequences on the classifier's operations. A protocol state machine presents the possible and permitted transitions on the instances of its context classifier, together with the operations which carry the transitions. In this manner, an instance lifecycle can be created for a classifier, by specifying the order in which the operations can be activated and the states through which an instance progresses during its existence.

Structural feature to be read.
A structured activity node is an executable activity node that may have an expansion into subordinate nodes as an activity group. The subordinate nodes must belong to only one structured activity node, although they may be nested.
Because of the concurrent nature of the execution of actions within and across activities, it can be difficult to guarantee the consistent access and modification of object memory. In order to avoid race conditions or other concurrency-related problems, it is sometimes necessary to isolate the effects of a group of actions from the effects of actions outside the group. This may be indicated by setting the mustIsolate attribute to true on a structured activity node. If a structured activity node is "isolated," then any object used by an action within the node cannot be accessed by any action outside the node until the structured activity node as a whole completes. Any concurrent actions that would result in accessing such objects are required to have their execution deferred until the completion of the node.
The incoming edges of the input pins of a StructuredActivityNode must have sources that are not within the StructuredActivityNode.

A variable is considered a connectable element.
Variables are elements for passing data between actions indirectly. A local variable stores values shared by the actions within a structured activity group but not accessible outside it. The output of an action may be written to a variable and read for the input to a subsequent action, which is effectively an indirect data flow path. Because there is no predefined relationship between actions that read and write variables, these actions must be sequenced by control flows to prevent race conditions that may occur between actions that read or write the same variable.
A variable is owned by a StructuredNode or Activity, but not both.

AggregationKind is an enumeration type that specifies the literals for defining the kind of aggregation of a property.
Indicates that the property has no aggregation.
Indicates that the property has a shared aggregation.
Indicates that the property is aggregated compositely, i.e., the composite object has responsibility for the existence and storage of the composed objects (parts).
CallConcurrencyKind is an enumeration type.
No concurrency management mechanism is associated with the operation and, therefore, concurrency conflicts may occur. Instances that invoke a behavioral feature need to coordinate so that only one invocation to a target on any behavioral feature occurs at once.
Multiple invocations of a behavioral feature may occur simultaneously to one instance, but only one is allowed to commence. The others are blocked until the performance of the currently executing behavioral feature is complete. It is the responsibility of the system designer to ensure that deadlocks do not occur due to simultaneous blocks.
Multiple invocations of a behavioral feature may occur simultaneously to one instance and all of them may proceed concurrently.
ConnectorKind is an enumeration type.
Indicates that the connector is an assembly connector.
Indicates that the connector is a delegation connector.

InteractionOperatorKind is an enumeration designating the different kinds of operators of combined fragments. The interaction operand defines the type of operator of a combined fragment.
The interactionOperator seq designates that the CombinedFragment represents a weak sequencing between the behaviors of the operands.
The interactionOperator alt designates that the CombinedFragment represents a choice of behavior. At most one of the operands will be chosen. The chosen operand must have an explicit or implicit guard expression that evaluates to true at this point in the interaction. An implicit true guard is implied if the operand has no guard.
The interactionOperator opt designates that the CombinedFragment represents a choice of behavior where either the (sole) operand happens or nothing happens. An option is semantically equivalent to an alternative CombinedFragment where there is one operand with non-empty content and the second operand is empty.
The interactionOperator break designates that the CombinedFragment represents a breaking scenario in the sense that the operand is a scenario that is performed instead of the remainder of the enclosing InteractionFragment. A break operator with a guard is chosen when the guard is true and the rest of the enclosing Interaction Fragment is ignored. When the guard of the break operand is false, the break operand is ignored and the rest of the enclosing InteractionFragment is chosen. The choice between a break operand without a guard and the rest of the enclosing InteractionFragment is done non-deterministically.
The interactionOperator par designates that the CombinedFragment represents a parallel merge between the behaviors of the operands. The OccurrenceSpecifications of the different operands can be interleaved in any way as long as the ordering imposed by each operand as such is preserved.
The interactionOperator strict designates that the CombinedFragment represents a strict sequencing between the behaviors of the operands. The semantics of strict sequencing defines a strict ordering of the operands on the first level within the CombinedFragment with interactionOperator strict. Therefore OccurrenceSpecifications within contained CombinedFragment will not directly be compared with other OccurrenceSpecifications of the enclosing CombinedFragment.
The interactionOperator loop designates that the CombinedFragment represents a loop. The loop operand will be repeated a number of times.
The interactionOperator critical designates that the CombinedFragment represents a critical region. A critical region means that the traces of the region cannot be interleaved by other OccurrenceSpecifications (on those Lifelines covered by the region). This means that the region is treated atomically by the enclosing fragment when determining the set of valid traces. Even though enclosing CombinedFragments may imply that some OccurrenceSpecifications may interleave into the region, such as e.g. with par-operator, this is prevented by defining a region.
The interactionOperator neg designates that the CombinedFragment represents traces that are defined to be invalid.
The interactionOperator assert designates that the CombinedFragment represents an assertion. The sequences of the operand of the assertion are the only valid continuations. All other continuations result in an invalid trace.
The interacionOperator ignore designates that there are some message types that are not shown within this combined fragment. These message types can be considered insignificant and are implicitly ignored if they appear in a corresponding execution. Alternatively, one can understand ignore to mean that the message types that are ignored can appear anywhere in the traces.
The interactionOperator consider designates which messages should be considered within this combined fragment. This is equivalent to defining every other message to be ignored.
This is an enumerated type that identifies the type of message.
sendEvent and receiveEvent are present
sendEvent present and receiveEvent absent
sendEvent absent and receiveEvent present
sendEvent and receiveEvent absent (should not appear)
This is an enumerated type that identifies the type of communication action that was used to generate the message.
The message was generated by a synchronous call to an operation.
The message was generated by an asynchronous call to an operation; i.e., a CallAction with isSynchronous = false.
The message was generated by an asynchronous send action.

The message designating the termination of another lifeline.
The message is a reply message to an operation call.

Indicates that object node tokens are ordered.
Indicates that object node tokens are queued in a last in, first out manner.
Indicates that object node tokens are queued in a first in, first out manner.
Parameter direction kind is an enumeration type that defines literals used to specify direction of parameters.
Indicates that parameter values are passed into the behavioral element by the caller.
Indicates that parameter values are passed into a behavioral element by the caller and then back out to the caller from the behavioral element.
Indicates that parameter values are passed from a behavioral element out to the caller.
Indicates that parameter values are passed as return values from a behavioral element back to the caller.
The datatype ParameterEffectKind is an enumeration that indicates the effect of a behavior on values passed in or out of its parameters.
Indicates that the behavior creates values.
Indicates that the behavior reads values.
Indicates that the behavior updates values.
Indicates that the behavior deletes values.
PseudostateKind is an enumeration type.
An initial pseudostate represents a default vertex that is the source for a single transition to the default state of a composite state. There can be at most one initial vertex in a region. The outgoing transition from the initial vertex may have a behavior, but not a trigger or guard.
DeepHistory represents the most recent active configuration of the composite state that directly contains this pseudostate; e.g. the state configuration that was active when the composite state was last exited. A composite state can have at most one deep history vertex. At most one transition may originate from the history connector to the default deep history state. This transition is taken in case the composite state had never been active before. Entry actions of states entered on the path to the state represented by a deep history are performed.
ShallowHistory represents the most recent active substate of its containing state (but not the substates of that substate). A composite state can have at most one shallow history vertex. A transition coming into the shallow history vertex is equivalent to a transition coming into the most recent active substate of a state. At most one transition may originate from the history connector to the default shallow history state. This transition is taken in case the composite state had never been active before. Entry actions of states entered on the path to the state represented by a shallow history are performed.
Join vertices serve to merge several transitions emanating from source vertices in different orthogonal regions. The transitions entering a join vertex cannot have guards or triggers.
Fork vertices serve to split an incoming transition into two or more transitions terminating on orthogonal target vertices (i.e. vertices in different regions of a composite state). The segments outgoing from a fork vertex must not have guards or triggers.
Junction vertices are semantic-free vertices that are used to chain together multiple transitions. They are used to construct compound transition paths between states. For example, a junction can be used to converge multiple incoming transitions into a single outgoing transition representing a shared transition path (this is known as an merge). Conversely, they can be used to split an incoming transition into multiple outgoing transition segments with different guard conditions. This realizes a static conditional branch. (In the latter case, outgoing transitions whose guard conditions evaluate to false are disabled. A predefined guard denoted 'else' may be defined for at most one outgoing transition. This transition is enabled if all the guards labeling the other transitions are false.) Static conditional branches are distinct from dynamic conditional branches that are realized by choice vertices (described below).
Choice vertices which, when reached, result in the dynamic evaluation of the guards of the triggers of its outgoing transitions. This realizes a dynamic conditional branch. It allows splitting of transitions into multiple outgoing paths such that the decision on which path to take may be a function of the results of prior actions performed in the same run-tocompletion step. If more than one of the guards evaluates to true, an arbitrary one is selected. If none of the guards evaluates to true, then the model is considered ill-formed. (To avoid this, it is recommended to define one outgoing transition with the predefined else guard for every choice vertex.) Choice vertices should be distinguished from static branch points that are based on junction points (described above).
An entry point pseudostate is an entry point of a state machine or composite state. In each region of the state machine or composite state it has a single transition to a vertex within the same region.
An exit point pseudostate is an exit point of a state machine or composite state. Entering an exit point within any region of the composite state or state machine referenced by a submachine state implies the exit of this composite state or submachine state and the triggering of the transition that has this exit point as source in the state machine enclosing the submachine or composite state.
Entering a terminate pseudostate implies that the execution of this state machine by means of its context object is terminated. The state machine does not exit any states nor does it perform any exit actions other than those associated with the transition leading to the terminate pseudostate. Entering a terminate pseudostate is equivalent to invoking a DestroyObjectAction.
TransitionKind is an enumeration type.
Implies that the transition, if triggered, occurs without exiting or entering the source state. Thus, it does not cause a state change. This means that the entry or exit condition of the source state will not be invoked. An internal transition can be taken even if the state machine is in one or more regions nested within this state.
Implies that the transition, if triggered, will not exit the composite (source) state, but it will apply to any state within the composite state, and these will be exited and entered.
Implies that the transition, if triggered, will exit the composite (source) state.
VisibilityKind is an enumeration type that defines literals to determine the visibility of elements in a model.
A public element is visible to all elements that can access the contents of the namespace that owns it.
A private element is only visible inside the namespace that owns it.
A protected element is visible to elements that have a generalization relationship to the namespace that owns it.
A package element is owned by a namespace that is not a package, and is visible to elements that are in the same package as its owning namespace. Only named elements that are not owned by packages can be marked as having package visibility. Any element marked as having package visibility is visible to all elements within the nearest enclosing package (given that other owning elements have proper visibility). Outside the nearest enclosing package, an element marked as having package visibility is not visible.
