- org.eclipse.persistence.sessions.SessionEventAdapter

All Implemented Interfaces:

EventListener, CoreSessionEventListener, SessionEventListener

Direct Known Subclasses:

org.eclipse.persistence.internal.jaxb.SessionEventListener
```
public abstract class SessionEventAdapter
extends Object
implements SessionEventListener
```
Purpose: To provide a trivial implemetation of SessionEventListener. You may subclass this class rather than implement the entire SessonEventListener interface in cases where only a small subset of the interface methods are needed.

  - missingDescriptor
```
public void missingDescriptor(SessionEvent event)
```
    PUBLIC: This event is raised on the session if a descriptor is missing for a class being persisted. This can be used to lazy register the descriptor or set of descriptors.
    
    Specified by:
    
    missingDescriptor in interface SessionEventListener
  - moreRowsDetected
```
public void moreRowsDetected(SessionEvent event)
```
    PUBLIC: This event is raised on the session after read object query detected more than a single row back from the database. The "result" of the event will be the call. Some applications may want to interpret this as an error or warning condition.
    
    Specified by:
    
    moreRowsDetected in interface SessionEventListener
  - noRowsModified
```
public void noRowsModified(SessionEvent event)
```
    PUBLIC: This event is raised on the session after update or delete SQL has been sent to the database but a row count of zero was returned.
    
    Specified by:
    
    noRowsModified in interface SessionEventListener
  - outputParametersDetected
```
public void outputParametersDetected(SessionEvent event)
```
    PUBLIC: This event is raised on the session after a stored procedure call has been executed that had output parameters. If the proc was used to override an insert/update/delete operation then EclipseLink will not be expecting any return value. This event mechanism allows for a listener to be registered before the proc is call to process the output values. The event "result" will contain a Record of the output values, and property "call" will be the StoredProcedureCall.
