All Implemented Interfaces:

org.eclipse.emf.common.command.CommandStack, org.eclipse.emf.transaction.impl.InternalTransactionalCommandStack, org.eclipse.emf.transaction.TransactionalCommandStack, org.eclipse.emf.workspace.IWorkspaceCommandStack

public class WorkspaceCommandStackImpl
extends org.eclipse.emf.transaction.impl.AbstractTransactionalCommandStack
implements org.eclipse.emf.workspace.IWorkspaceCommandStack

Implementation of a transactional command stack that delegates execution of commands to an IOperationHistory.

This is the command stack implementation used by editing domains created by the WorkspaceEditingDomainFactory.

This command stack is a copy of the one provided by or.eclipse.emf.workspace plug-in with some modifications to fix bugs.
