true if this ITransactionalOperation has no effect, otherwise false.

redo

public IStatus redo(IProgressMonitor monitor,
 IAdaptable info)
             throws ExecutionException

Specified by:

redo in class AbstractOperation

Throws:

ExecutionException

undo

public IStatus undo(IProgressMonitor monitor,
 IAdaptable info)
             throws ExecutionException

Specified by:
