Examples of org.eclipse.text.edits.TextEditGroup

org.eclipse.text.edits.TextEditGroup
A text edit group combines a list of {@link TextEdit}s and a name into a single object. The name must be a human readable string use to present the text edit group in the user interface.
Clients may extend this class to add extra information to a text edit group.
