All Implemented Interfaces:
Serializable, Pointcut, MethodMatcher

Perl5-style regular expression pointcut. JavaBean properties are:

pattern: Perl5 regular expression for the fully-qualified method names to match
patterns: alternative property taking a String array of patterns. The result will be the union of these patterns.

Note: the regular expressions must be a match. For example, .*get.* will match com.mycom.Foo.getBar(). get.* will not.

Currently uses the Jakarta ORO regular expression library. Does not require JDK 1.4+, in contrast to JdkRegexpMethodPointcut.
