containInA(APK pkb) It returns true the multivalued relation contains the bean A defined
by the primary key specified by the parameter.
public void
ejbActivate() 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.
public boolean containAllInA(Collection pkbs) throws FinderException(Code)
containInA
public boolean containInA(APK pkb) throws FinderException(Code)
It returns true the multivalued relation contains the bean A defined
by the primary key specified by the parameter.
This method has the transactional attribut TX_SUPPORTS.
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.
ejbCreate
publicString ejbCreate(String idb1, int idb2) throws CreateException, DuplicateKeyException(Code)
The Entity bean can define 0 or more ejbCreate methods.
throws: CreateException - Failure to create an entity EJB object. throws: DuplicateKeyException - An object with the same key already exists.
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 proper transaction context.
throws: EJBException - Thrown by the method to indicate a failure caused bya system-level error.
A container invokes this method on an instance before the instance
becomes disassociated with a specific EJB object.
ejbPostCreate
public void ejbPostCreate(String idb1, int idb2) throws CreateException(Code)
There must be an ejbPostCreate par ejbCreate method
throws: CreateException - Failure to create an entity EJB object.
ejbRemove
public void ejbRemove() throws RemoveException(Code)
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.
throws: RemoveException - The enterprise Bean does not allow destruction of the object. throws: EJBException - - Thrown by the method to indicate a failure caused by a system-levelerror.
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 proper transaction context.
throws: EJBException - Thrown by the method to indicate a failure caused bya system-level error.
public void setEntityContext(EntityContext ctx)(Code)
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.
Parameters: ctx - - An EntityContext interface for the instance. The instanceshould store the reference to the context in an instance variable. throws: EJBException - Thrown by the method to indicate a failure caused by asystem-level error.
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.
throws: EJBException - Thrown by the method to indicate a failure caused by asystem-level error.
