Class DefaultUndoManager

java.lang.Object
org.eclipse.jface.text.DefaultUndoManager
All Implemented Interfaces:
IUndoManager, IUndoManagerExtension
@Deprecated(forRemoval=true, since="2025-03") public class DefaultUndoManager extends Object implements IUndoManager, IUndoManagerExtension
Deprecated, for removal: This API element is subject to removal in a future version.
As of 3.2, replaced by TextViewerUndoManager
Standard implementation of IUndoManager.

It registers with the connected text viewer as text input listener and document listener and logs all changes. It also monitors mouse and keyboard activities in order to partition the stream of text changes into undo-able edit commands.

Since 3.1 this undo manager is a facade to the global operation history.

The usage of IAdaptable in the JFace layer has been approved by Platform UI, see https://bugs.eclipse.org/bugs/show_bug.cgi?id=87669#c9
