| JEntityContext | | public class JEntityContext extends JContext implements EntityContext,Synchronization(Code) | | This class implements javax.ejb.EntityContext interface. An Entitycontext is
bound to a bean instance. To be used, it must be associated to a
JEntitySwitch, and possibly to a Transaction. In case the Context is used
inside a Transaction, we use the Synchronization interface to be aware of
transaction demarcations.

| Constructor Summary | |
| public | JEntityContext(JEntityFactory bf, EntityBean eb)
Constructs an EntityContext the Context has to be initialized after this. |
| beanCoord | | Transaction beanCoord(Code) | | Transaction related to this synchronization
|
| ismarkedremoved | | boolean ismarkedremoved(Code) | | true between a remove and the commit
|
| isnewinstance | | boolean isnewinstance(Code) | | true if just created in this transaction
|
| JEntityContext | | public JEntityContext(JEntityFactory bf, EntityBean eb)(Code) | | Constructs an EntityContext the Context has to be initialized after this.
Parameters:
bf - - the JEntityFactory
Parameters:
eb - - the Enterprise Bean instance |
| activate | | public void activate(boolean doactivate)(Code) | | Activate instance.
Parameters:
doactivate - True if ejbActivate() is called before ejbLoad() |
| afterCompletion | | public void afterCompletion(int status)(Code) | | This method is typically called after the transaction is committed.
Parameters:
status - The status of the transaction completion. |
| beforeCompletion | | public void beforeCompletion()(Code) | | This method is typically called at beforeCompletion
|
| detachTx | | public void detachTx()(Code) | | Detach this Context from tx
|
| get2EJBLocalObject | | public EJBLocalObject get2EJBLocalObject() throws IllegalStateException(Code) | | Obtain a reference to the EJB local object that is currently associated
with the instance.
(internal use of getEJBLocalObject with no check).
The EJB local object currently associated with the instance.
throws:
IllegalStateException - - if the instance invokes this method whilethe instance is in a state that does not allow the instance toinvoke this method, or if the instance does not have a localinterface. |
| getEJBLocalObject | | public EJBLocalObject getEJBLocalObject() throws IllegalStateException(Code) | | Obtain a reference to the EJB local object that is currently associated
with the instance.
The EJB local object currently associated with the instance.
throws:
IllegalStateException - - if the instance invokes this method whilethe instance is in a state that does not allow the instance toinvoke this method, or if the instance does not have a localinterface. |
| getEJBObject | | public EJBObject getEJBObject() throws IllegalStateException(Code) | | Obtains a reference to the EJB object that is currently associated with
the instance.
The EJB object currently associated with the instance.
throws:
IllegalStateException - Thrown if the instance invokes this methodwhile the instance is in a state that does not allow the instanceto invoke this method. |
| getEntityFactory | | public JEntityFactory getEntityFactory()(Code) | | JEntityFactory accessor
the JEntityFactory |
| getEntitySwitch | | public JEntitySwitch getEntitySwitch()(Code) | | JEntitySwitch accessor
the JEntitySwitch |
| getInstance | | public EntityBean getInstance() throws RemoteException(Code) | | Returns the bean instance of this context Used in the generated classes
to retrieve the instance
the bean instance
throws:
RemoteException - if no instance. |
| getMyTx | | public Transaction getMyTx()(Code) | | the transaction associated to this context. |
| getPrimaryKey | | public Object getPrimaryKey() throws IllegalStateException(Code) | | Obtains the primary key of the EJB object that is currently associated
with this instance.
The EJB object currently associated with the instance.
throws:
IllegalStateException - Thrown if the instance invokes this methodwhile the instance is in a state that does not allow the instanceto invoke this method. |
| initEntityContext | | public boolean initEntityContext(JEntitySwitch bs)(Code) | | Reinit Context for reuse
Parameters:
bs - - The Bean Switch this Context belongs to. |
| isDirty | | public boolean isDirty()(Code) | | true if instance has been modified |
| isInitialized | | public boolean isInitialized()(Code) | | True if Entity Switch has been already associated |
| isMarkedRemoved | | public boolean isMarkedRemoved()(Code) | | Check if context has been marked removed
true when instance is marked removed. |
| isNewInstance | | public boolean isNewInstance()(Code) | | Check if context is a newly created instance
true when instance has been created in the current transaction. |
| passivate | | public boolean passivate()(Code) | | passivate this instance
true if passivated. |
| razEntityContext | | public void razEntityContext()(Code) | | Raz Context before freeing it. This is mainly for garbage collector.
|
| reuseEntityContext | | public void reuseEntityContext(boolean newtrans)(Code) | | reuse EntityContext for another transaction. optimization: don't pass it
by the pool.
Parameters:
newtrans - true if new transaction |
| setDirty | | public void setDirty(boolean d)(Code) | | Set the dirty flag: true = instance modified.
|
| setEntitySwitch | | public void setEntitySwitch(JEntitySwitch bs)(Code) | | set the EntitySwitch
Parameters:
bs - - the EntitySwitch |
| setNewInstance | | public void setNewInstance()(Code) | | Set new instance flag
|
| setRemoved | | public void setRemoved() throws RemoteException, RemoveException(Code) | | Mark this context as removed. Complete removing will be achieved at the
end of the transaction.
throws:
RemoteException - ejbRemove failed
throws:
RemoveException - ejbRemove failed |
| setRunningTx | | public boolean setRunningTx(Transaction tx)(Code) | | Associate transaction to ths Context
Parameters:
tx - true if correctly associated, false if was already done. |
