org.eclipse.persistence.logging
Class AbstractSessionLog

java.lang.Object
  extended by org.eclipse.persistence.logging.AbstractSessionLog
All Implemented Interfaces:
java.lang.Cloneable, SessionLog
Direct Known Subclasses:
DefaultSessionLog, JavaLog, ServerLog

public abstract class AbstractSessionLog
extends java.lang.Object
implements SessionLog, java.lang.Cloneable

Represents the abstract log that implements all the generic logging functions. It contains a singleton SessionLog that logs messages from outside any EclipseLink session. The singleton SessionLog can also be passed to an EclipseLink session when messages are logged through that session. When JDK1.4 is used, a singleton JavaLog is created. Otherwise a singleton DefaultSessionLog is created.
