  org.eclipse.persistence.sessions.SessionEventAdapter

All Implemented Interfaces:

java.util.EventListener, SessionEventListener

public abstract class SessionEventAdapter
extends java.lang.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.

SessionEventAdapter

public SessionEventAdapter()

Method Detail

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.

Specified by:

outputParametersDetected in interface SessionEventListener

postAcquireClientSession

public void postAcquireClientSession(SessionEvent event)

PUBLIC: This event is raised on the client session after creation/acquiring.

Specified by:

postAcquireClientSession in interface SessionEventListener
