Class ReplacedTextMapper

java.lang.Object

com.vladsch.flexmark.util.sequence.ReplacedTextMapper

public class ReplacedTextMapper
extends java.lang.Object

Class which tracks text replacements to provide original offset from modified offset.

This is needed when the original based sequence needs to be un-escaped but offsets to original escaped text are needed.

These replacements can be nested so that you can track replacements of replaced text. To add nested replacements use startNestedReplacement()

when isModified() returns true then the text mapper is already used and nested replacements need to be applied
