Workspace Integration Example
Introduction
This example describes the usage of the transaction framework through the workspace
integration. It demonstrates how a UI could be hooked up using the eclipse operation
history framework to allow UI and non-UI threads to read and make changes to a
transactional editing domain.

Description
This example plug-in is named org.eclipse.emf.workspace.examples.library.editor.
This plug-in contributes a new EXTLibrary editor for opening and modifying existing library
files:
-
An editor is opened for each resource. The editor only shows one resource. When other
resources are loaded (eg. proxy resolution causes anothe resource to be loaded) into the
editing domain, another editor is opened for that resource.
-
The undo/redo of each editor is governed by an IOperationHistory and only the operations
that affect the resource are presented in that menu.
-
Example Background Task: This actions performs a read task in the background to
demonstrate how the UI can be blocked for making changes while this read task is in progress.

Usage
Refer to this example if you need:
- Multiple editors sharing the same editing domain
- Integration of a transactional editing domain into the eclipse IOperationHistory
- Management of multiple read/write threads on a single EMF-style editing domain
