Assembly: Microsoft.VisualStudio.Text.Logic (in Microsoft.VisualStudio.Text.Logic.dll)
Thetype exposes the following members.
|AttachHistory||Attaches an existing ITextUndoHistory to a text buffer. The buffer must not already be mapped in this registry.|
|GetHistory||Gets a history associated with the text buffer, but does not create a new one.|
|RegisterHistory||Gets, and if necessary creates, a history associated with the context.|
|RemoveHistory||Removes all mappings to a given ITextUndoHistory in this registry, if any exist.|
|TryGetHistory||Gets a history associated with the text buffer, but does not create a new one.|
This is a MEF component part, and should be imported as follows:
[Import] ITextUndoHistoryRegistry registry = null;
