public abstract class GenericRegexMatcher
extends 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).

compile

public void compile(java.lang.Object[][] patterns)
             throws org.apache.oro.text.regex.MalformedPatternException

Throws:

org.apache.oro.text.regex.MalformedPatternException

init

public abstract void init()
                   throws javax.mail.MessagingException

Description copied from class: GenericMatcher

A convenience method which can be overridden so that there's no need to call super.init(config).

Instead of overriding init(MatcherConfig), simply override this method and it will be called by GenericMatcher.init(MatcherConfig config). The MatcherConfig object can still be retrieved via getMatcherConfig().

Overrides:

init in class GenericMatcher

Throws:

javax.mail.MessagingException

match

public java.util.Collection match(Mail mail)
                           throws javax.mail.MessagingException

Description copied from class: GenericMatcher

Called by the matcher container to allow the matcher to process a message.

This method is declared abstract so subclasses must override it.

Specified by:

match in interface Matcher

Specified by:

match in class GenericMatcher

Parameters:

mail - - the Mail object that contains the MimeMessage and routing information

Returns:

java.util.Collection - the recipients that the mailet container should have the mailet affect.

Throws:

MessagingException - - if an message or address parsing exception occurs or an exception that interferes with the matcher's normal operation
