Class TransactionalEditingDomainListenerImpl


java.lang.Object
  
org.eclipse.emf.transaction.TransactionalEditingDomainListenerImpl

All Implemented Interfaces:: EventListener, TransactionalEditingDomainListener

public class TransactionalEditingDomainListenerImpl
extends Object
implements TransactionalEditingDomainListener
extends Object
implements TransactionalEditingDomainListener

A default implementation of the TransactionalEditingDomainListener interface that does nothing in response to those call-backs, but which is useful for subclassing to handle just the interesting events.

Since:: 1.3

Constructor Summary

TransactionalEditingDomainListenerImpl ()
          Initializes me.

Method Summary

void editingDomainDisposing ( TransactionalEditingDomainEvent event)
           Signals that the transactional editing domain to which the lister is attached is to be disposed.

void transactionClosed ( TransactionalEditingDomainEvent event)
           Signals that a transaction has closed, either with a successful commit or with a roll-back.

void transactionClosing ( TransactionalEditingDomainEvent event)
           Signals that a transaction has finished its work and is about to close.

void transactionInterrupted ( TransactionalEditingDomainEvent event)
           Signals that a transaction that has requested activation was interrupted before it could start.

void transactionStarted ( TransactionalEditingDomainEvent event)
           Signals that a transaction has been activated.

void transactionStarting ( TransactionalEditingDomainEvent event)
           Signals that a transaction has requested activation, but is not yet started.

Method Detail

editingDomainDisposing

public void editingDomainDisposing(
TransactionalEditingDomainEvent event)

Description copied from interface: TransactionalEditingDomainListener

Signals that the transactional editing domain to which the lister is attached is to be disposed. Disposal result, among other things, in the removal of the listener from it.

Specified by:: editingDomainDisposing in interface TransactionalEditingDomainListener

Parameters:: event - indicates the editing domain that is being disposed. The event has no transaction

transactionClosed

public void transactionClosed(
TransactionalEditingDomainEvent event)

Description copied from interface: TransactionalEditingDomainListener

Signals that a transaction has closed, either with a successful commit or with a roll-back. The status of the transaction will indicate which has occurred; an IStatus.ERROR indicates roll-back. This event is sent after all post-commit notifications have gone out to ResourceSetListeners.

This event is not sent for nested transactions.

Specified by:: transactionClosed in interface TransactionalEditingDomainListener

Parameters:: event - indicates the transaction that has closed

transactionClosing

public void transactionClosing(
TransactionalEditingDomainEvent event)

Description copied from interface: TransactionalEditingDomainListener

Signals that a transaction has finished its work and is about to close. This may be the beginning of the normal commit sequence of trigger firing followed by validation (subsequently rolling back, if necessary), or an explicit roll-back requested by the transaction, itself.

This event is not sent for nested transactions, nor for a transaction's entry into the yielded state.

Specified by:: transactionClosing in interface TransactionalEditingDomainListener

Parameters:: event - indicates the transaction that is about to close

transactionInterrupted

public void transactionInterrupted(
TransactionalEditingDomainEvent event)

Description copied from interface: TransactionalEditingDomainListener

Signals that a transaction that has requested activation was interrupted before it could start. Thus, this indicates a failed start.

This event is not sent for nested transactions.

Specified by:: transactionInterrupted in interface TransactionalEditingDomainListener

Parameters:: event - indicates the transaction that was interrupted

transactionStarted

public void transactionStarted(
TransactionalEditingDomainEvent event)

Description copied from interface: TransactionalEditingDomainListener

Signals that a transaction has been activated.

This event is not sent for nested transactions, nor for a transaction's resumption from the yielded state.

Specified by:: transactionStarted in interface TransactionalEditingDomainListener

Parameters:: event - indicates the transaction that has started

transactionStarting

public void transactionStarting(
TransactionalEditingDomainEvent event)

Description copied from interface: TransactionalEditingDomainListener

Signals that a transaction has requested activation, but is not yet started. Note that any number of transactions may be in this state simultaneously, on different threads, but obviously only one will actually start.

This event is not sent for nested transactions, nor for a transaction's resumption from the yielded state.
