public class MetaFilter extends Object implements javax.servlet.Filter
Generic container filter to manage routing to different pipelines.Callers can create and configure a new processing pipeline by using one of the
serve(String)
orserveRegex(String)
methods to allocate a binder for a particular URL pattern.Registered filters and servlets are initialized lazily, usually during the first request. Once initialized the bindings in this servlet cannot be modified without destroying the servlet and thereby destroying all registered filters and servlets.
