ClearFormatOperation

Class | public class ClearFormatOperation
Inheritance | ClearFormatOperation FlowTextOperation FlowOperation Object

Language Version : | ActionScript 3.0

Runtime Versions : | Flash Player 10, AIR 1.5

The ClearFormatOperation class encapsulates a way to undefine formats.

An UndefineFormatOperation undefines properties set in the leaf format to the text in the specified range (no change is made if the specified range is a single point). It undefines properties set in the paragraph format to any paragraphs at least partially within the range (or a single paragraph if the range is a single point). And it undefines properties set in the container format to any containers at least partially within the range (or a single container if the range is a single point).
