All Implemented Interfaces:

Component, LogEnabled, Matcher, PreparableMatcher

Direct Known Subclasses:

AbstractRegexpMatcher

public abstract class AbstractPreparableMatcher
extends AbstractLogEnabled
implements PreparableMatcher

A matcher that can prepare patterns during sitemap setup for faster match at request time. This is also a regular matcher, meaning the sitemap can decide either to prepare the pattern or to match with a request-time evaluated pattern (for {..} substitution).
