Class EjbInvocation

java.lang.Object
  org.glassfish.api.invocation.ComponentInvocation
      com.sun.ejb.EjbInvocation

All Implemented Interfaces:

InterceptorManager.AroundInvokeContext, TransactionOperationsManager, java.lang.Cloneable, InvocationContext, EJBInvocation

public class EjbInvocation
extends ComponentInvocation
implements InvocationContext, TransactionOperationsManager, java.lang.Cloneable, EJBInvocation, InterceptorManager.AroundInvokeContext

The EjbInvocation object contains state associated with an invocation on an EJB or EJBHome (local/remote). It is usually created by generated code in *ObjectImpl and *HomeImpl classes. It is passed as a parameter to Container.preInvoke() * and postInvoke(), which are called by the EJB(Local)Object/EJB(Local)Home before and after an invocation.
