Class TransactionalDualCompareCommandStack
- java.lang.Object
-
- org.eclipse.emf.compare.command.impl.TransactionalDualCompareCommandStack
-
- All Implemented Interfaces:
CommandStack,ICompareCommandStack,IDisposable
public class TransactionalDualCompareCommandStack extends Object implements ICompareCommandStack, IDisposable
ICompareCommandStackimplementation that will delegate to two given command stacks; one for each side of the comparison.This implementation is one of the most robust delegating implementation we can do. If an error occurs during execution of a command, only the dirty state will be reset, all models will stay correct.
