Class StringRegExEqualsTest

java.lang.Object
wt.rule.algorithm.StringRegExEqualsTest
All Implemented Interfaces:
RuleAlgorithm
public final class StringRegExEqualsTest extends Object implements RuleAlgorithm
Given an attribute and a value, with "*" in the value, determine the equality using Regular Expression related concepts. The point here is to make available the java.util.regex implementation of regular expression matching. The return would be true if it finds a match and the match is the whole string argument. Force arg[0] using toString() first before comparison. If the length of the arguments passed is not two, throw exception.Force arg[0] using toString() first before comparison. If arg[1] passed is not String, throw exception. return Pattern.matches(arg[1], arg[0].toString()); OR: Pattern p=Pattern.compile(arg[1]); Matcher m=p.matcher(arg[0].toString()); Return m.matches(); true if, and only if, the entire input sequence matches this matcher's pattern
