org.eclipse.text.edits.MoveTargetEdit
A move target edit denotes the target of a move operation. Move
target edits are only valid inside an edit tree if they have a
corresponding source edit. Furthermore a target edit can't
can't be a direct or indirect child of its associated source edit.
Violating one of two requirements will result in a
MalformedTreeException when executing the edit tree.
Move target edits can't be used as a parent for other edits.
Trying to add an edit to a move target edit results in a
MalformedTreeException as well.

This method should not be called from outside the framework.
Please use
