public interface: EntityBean [javadoc | source]

All Implemented Interfaces:
    EnterpriseBean

The EntityBean interface is implemented by every entity enterprise Bean class. The container uses the EntityBean methods to notify the enterprise Bean instances of the instance's life cycle events.
Method from javax.ejb.EntityBean Summary:
ejbActivate,   ejbLoad,   ejbPassivate,   ejbRemove,   ejbStore,   setEntityContext,   unsetEntityContext
Method from javax.ejb.EntityBean Detail:
 public  void ejbActivate() throws EJBException, RemoteException

    A container invokes this method when the instance is taken out of the pool of available instances to become associated with a specific EJB object. This method transitions the instance to the ready state.

    This method executes in an unspecified transaction context.

 public  void ejbLoad() throws EJBException, RemoteException

    A container invokes this method to instruct the instance to synchronize its state by loading it state from the underlying database.

    This method always executes in the transaction context determined by the value of the transaction attribute in the deployment descriptor.

 public  void ejbPassivate() throws EJBException, RemoteException

    A container invokes this method on an instance before the instance becomes disassociated with a specific EJB object. After this method completes, the container will place the instance into the pool of available instances.

    This method executes in an unspecified transaction context.

 public  void ejbRemove() throws RemoveException, EJBException, RemoteException

    A container invokes this method before it removes the EJB object that is currently associated with the instance. This method is invoked when a client invokes a remove operation on the enterprise Bean's home interface or the EJB object's remote interface. This method transitions the instance from the ready state to the pool of available instances.

    This method is called in the transaction context of the remove operation.

 public  void ejbStore() throws EJBException, RemoteException

    A container invokes this method to instruct the instance to synchronize its state by storing it to the underlying database.

    This method always executes in the transaction context determined by the value of the transaction attribute in the deployment descriptor.

 public  void setEntityContext(EntityContext ctx) throws EJBException, RemoteException

    Set the associated entity context. The container invokes this method on an instance after the instance has been created.

    This method is called in an unspecified transaction context.

 public  void unsetEntityContext() throws EJBException, RemoteException

    Unset the associated entity context. The container calls this method before removing the instance.

    This is the last method that the container invokes on the instance. The Java garbage collector will eventually invoke the finalize() method on the instance.

    This method is called in an unspecified transaction context.
