/** An InteractionSpec holds properties for driving an Interaction
* with an EIS instance. An InteractionSpec is used by an Interaction
* to execute the specified function on an underlying EIS.
*
* The CCI specification defines a set of standard properties for
* an InteractionSpec. An InteractionSpec implementation is not
* required to support a standard property if that property does
* not apply to its underlying EIS.
*
*
The InteractionSpec implementation class must provide getter and
* setter methods for each of its supported properties. The getter and
* setter methods convention should be based on the Java Beans design
* pattern.
*
*
The standard properties are as follows:
*
* - FunctionName: name of an EIS function
*
- InteractionVerb: mode of interaction with an EIS instance:
* SYNC_SEND, SYNC_SEND_RECEIVE, SYNC_RECEIVE
*
- ExecutionTimeout: the number of milliseconds an Interaction
* will wait for an EIS to execute the specified function
*
*
* The following standard properties are used to give hints to an
* Interaction instance about the ResultSet requirements:
*
* - FetchSize
*
- FetchDirection
*
- MaxFieldSize
*
- ResultSetType
*
- ResultSetConcurrency
*
*
* A CCI implementation can provide additional properties beyond
* that described in the InteractionSpec interface. Note that the
* format and type of the additional properties is specific to an EIS
* and is outside the scope of the CCI specification.
*
*
It is required that the InteractionSpec interface be implemented
* as a JavaBean for the toolability support. The properties on the
* InteractionSpec implementation class should be defined through the
* getter and setter methods pattern. An implementation class for
* InteractionSpec interface is required to implement the
* java.io.Serializable interface.
