GenericRegexMatcherpublic abstract class GenericRegexMatcher extends org.apache.mailet.GenericMatcher | This is a generic matcher that uses regular expressions. If any of
the regular expressions match, the matcher is considered to have
matched. This is an abstract class that must be subclassed to feed
patterns. Patterns are provided by calling the compile method. A
subclass will generally call compile() once during init(), but it
could subclass match(), and call it as necessary during message
processing (e.g., if a file of expressions changed). |
