org.eclipse.emf.transaction.impl
Class TriggerCommandTransaction

java.lang.Object
  extended by 

org.eclipse.emf.transaction.impl.TransactionImpl
      extended by 

org.eclipse.emf.transaction.impl.EMFCommandTransaction
          extended by 
org.eclipse.emf.transaction.impl.TriggerCommandTransaction
All Implemented Interfaces:
InternalTransaction, Transaction

public class TriggerCommandTransaction
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.
