Interface EntityContextExtension

All Superinterfaces:

javax.ejb.EJBContext, EJBContextExtension, javax.ejb.EntityContext

public interface EntityContextExtension
extends javax.ejb.EntityContext, EJBContextExtension

The EntityContextExtension interface may be used by an Entity EJB to invoke WebSphere-specific EJB Container services.

An Entity EJB may invoke the EntityContextExtension methods by casting the context object passed into the EJB's setEntityContext() method, to com.ibm.websphere.ejbcontainer.EntityContextExtension. Typically the code in setEntityContext() assigns the context object to a bean instance variable for later use by other bean methods.

In WebSphere, all javax.ejb.EntityContext objects also implement this interface. This allows the bean to use a single 'context' instance variable (of type EntityContextExtension) and be able to invoke EJB specification-defined methods as well as WebSphere-defined methods on the same context object. It is also possible, of course, to assign the context object to two instance variables, one of type javax.ejb.EntityContext and another of type com.ibm.websphere.ejbcontainer.EntityContextExtension.

Note: Some of the methods on this interface may result in behavior not compliant with the official EJB specification. If this is the case, the documentation for that method will indicate so.
