Class MatchMap

java.lang.Object

org.apache.manifoldcf.crawler.connectors.sharepoint.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.

Constructor Detail

MatchMap

public MatchMap()

Constructor. Build an empty matchmap.

MatchMap

public MatchMap(java.lang.String stringForm)

public java.lang.String getReplaceString(int index)

Get a specific replace string

deleteMatchPair

public void deleteMatchPair(int index)

Delete a specified match/replace string pair

insertMatchPair

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

                             java.lang.String input)

Escape a string so it is verbatim

toString

public java.lang.String toString()

Convert the matchmap to string form.

Overrides:

toString in class java.lang.Object

stuff

                            java.lang.String value)

Stuff characters

translate
