java.lang.Objectorg.eclipse.text.edits.TextEdit
org.eclipse.text.edits.UndoEdit
This class encapsulates the reverse changes of an executed text edit tree. To apply an undo memento to a document use method apply(IDocument).
Clients can add additional children to an undo edit nor can they add an undo edit as a child to another edit. Doing so results in both cases in a MalformedTreeException.

Method Detail |
protected TextEdit doCopy()
Implementers of this method should use the copy constructor Edit#Edit(Edit source) to initialize the edit part of the copy. Implementors aren't responsible to actually copy the children or to set the right parent.
This method should not be called from outside the framework. Please use copy to create a copy of a edit tree.
protected void accept0(TextEditVisitor visitor)
General template for implementation on each concrete TextEdit class:
boolean visitChildren = visitor.visit(this); if (visitChildren) { acceptChildren(visitor); }Note that the caller (accept) takes care of invoking visitor.preVisit(this) and visitor.postVisit(this).
