/**
*
*
* Apache Trinidad tree components are used to display hierarchical data.
* For example,
* if we have a personnel organization chart depicting all the direct
* reports under
* each employee, we could use a tree component to display this
* chart. While each element (employee) in the hierarchy may have any
* number of
* child elements, each element can only have one parent element.
*
*
*
*
* The Apache Trinidad tree components use a model to access the data in the
* underlying hierarchy. The specific model class is
* org.apache.myfaces.trinidad.model.TreeModel .
*
* You may find the
* org.apache.myfaces.trinidad.model.ChildPropertyTreeModel class
* useful when constructing a TreeModel .
*
*
*
*
*
* The tree components use a stamping strategy similar to the Trinidad Table
* component. Child components are used to display the
* data for each element in the tree. Each child component is not recreated
* per element; instead, each child is repeatedly
* rendered (stamped) once per element. Because of this stamping
* behavior, only certain types of components are supported as
* children. Supported components include all
* components with no behavior and most components that implement the
* EditableValueHolder or ActionSource interfaces.
*
*
* Each time a child component is stamped, the data for the current
* element is copied into an EL reachable property. The
* name of this property is defined by the var
* property on
* the tree component. Once the tree has completed rendering, this property is
* removed (or reverted back to its previous value).
*
*
*
*
* When the user expands or collapses a subtree the tree
* generates a DisclosureEvent . This event has an
* isExpanded method that returns whether the user wants
* to expand or collapse the subtree of a particular element. That
* particular element is made current on the Tree before the event is
* delivered.
*
*
*
*
*
* The Trinidad tree components use an instance of the
* org.apache.myfaces.trinidad.model.RowKeySet
* class to keep track
* of which elements are expanded. This instance is stored
* as the "expandedRowKeys" attribute on the component. You may use this
* instance to programmatically control the expand/collapse state of an
* element in the hierarchy.
*
*
*
* Events:
*
*
* Type
* Phases
* Description
*
*
* org.apache.myfaces.trinidad.event.RowDisclosureEventApply
Request
Values
Invoke
Application
* The expansion event is generated for a table when the detail facet of a row is expanded or collapsed. For tree or a treeTable, the expansion
event is generated when tree nodes are expanded or collapsed.
*
*
* org.apache.myfaces.trinidad.event.SelectionEventApply
Request
Values
Invoke
Application
* The selection event is delivered when the table selection
changes.
*
*
* org.apache.myfaces.trinidad.event.FocusEventApply
Request
Values
Invoke
Application
* Event delivered when user clicks to focus on (or zoom into) a particular element's subtree of children.
The TreeTable responds to this event by modifying the "focusPath" property appropriately.
Subsequently, any registered FocusListener instances are called.
*
*
* org.apache.myfaces.trinidad.event.AttributeChangeEventInvoke
Application
Apply
Request
Values
* Event delivered to describe an attribute change. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change event might include the width of a column that supported client-side resizing.
