Class Regex

java.lang.Object
  ccs.utils.Regex

public class Regex
extends java.lang.Object

A Regular Expression matcher with a simpilified syntax and limited functionality. The only special characters are ? (match exactly one character) and * (match 0 or more characters). * is "greedy" - it will match as many characters as it can, but will back off as required for the match to succeed. In general this behaviour gives the results you'd expect.

Historically this class implemented the matching itself; however, Java 1.4 provides a full-featured PERL-compatible Regex system with much better performance, so this class has been re-written as a wrapper around that.

Constructor Summary

Regex(java.lang.String pattern, boolean isSense)
Create a Regex which matches the given pattern.

Method Summary

java.lang.String	getPattern() Returns the pattern.
boolean	getSense() Returns whether matching is case-sensitive.
boolean	matches(java.lang.String a) Returns whether the given string matches the current pattern, with default case-sensitivity.
static java.lang.String	translate(java.lang.String src) Translate the simplified regex syntax used by this class into PERL5 regex syntax.
