Class: Insert

Defined in:	lib/Types/BasicTypes.coffee
Inherits:	Operation

Overview

A simple insert-type operation.

An insert operation is always positioned between two other insert operations. Internally this is realized as associative lists, whereby each insert operation has a predecessor and a successor. For the sake of efficiency we maintain two lists: - The short-list (abbrev. sl) maintains only the operations that are not deleted - The complete-list (abbrev. cl) maintains all operations
