Class RewritingStringTransformer

java.lang.Object

org.archive.wayback.replay.html.rewrite.RewritingStringTransformer

All Implemented Interfaces:

StringTransformer

public class RewritingStringTransformer
extends Object
implements StringTransformer

StringTransformer that manages a collection of named RewriteRules, and applies one or more of them whose name matching ParseContext.getOraclePolicy() value.

Typically set up for FastArchivalUrlReplayParseEventHandler.setJsBlockTrans(StringTransformer) for rewriting embedded JavaScript based on external rewrite rule database.

Caveat: While this may be useful for rewriting other kinds of text, current implementation works only for embedded JavaScript block (it has explicit context check.)
