Class TriggerCommandTransaction


java.lang.Object
  

org.eclipse.emf.transaction.impl.TransactionImpl
      

org.eclipse.emf.transaction.impl.EMFCommandTransaction
          
org.eclipse.emf.transaction.impl.TriggerCommandTransaction

All Implemented Interfaces:: InternalTransaction, Transaction

public class TriggerCommandTransaction
extends EMFCommandTransaction
extends EMFCommandTransaction

A transaction implementation used by the command stack to wrap the execution of TriggerCommands, to provide them the write access that they need. This transaction does not propagate its change description to the parent, because that is handled separately via CommandChangeDescriptions.

Constructor Summary

TriggerCommandTransaction ( TriggerCommand command, InternalTransactionalEditingDomain domain, Map<?,?> options)
          Initializes me with my command, editing domain, and options.

Method Summary

void addTriggers ( TriggerCommand triggers)
          Overrides the inherited implementation to simply propagate triggers to my parent, because it's the transaction that the outside world can see.

protected void close ()
          Extends the inherited implementation by first clearing my change description, so that I will not propagate these changes upwards.
