Class MatchMap

java.lang.Object

org.apache.manifoldcf.crawler.connectors.meridio.MatchMap

public class MatchMap
extends java.lang.Object

An instance of this class describes a "match map", which describes a translation of an input string using regexp technology. A match map consists of multiple clauses, which are fired in sequence. Each clause is a regexp search and replace, where the replace string can include references to the groups present in the search regexp. MatchMaps can be converted to strings in two different ways. The first way is to build a single string of the form "match1=replace1&match2=replace2...". Strings of this kind must escape & and = characters in the match and replace strings, where found. The second way is to generate an array of match strings and a corresponding array of replace strings. This method requires no escaping of the string contents.

deleteMatchPair

public void deleteMatchPair(int index)

Delete a specified match/replace string pair

insertMatchPair

public void insertMatchPair(int index,
                            java.lang.String match,
