Class MetaFilter

java.lang.Object

org.eclipse.jgit.http.server.glue.MetaFilter

All Implemented Interfaces:

javax.servlet.Filter

Direct Known Subclasses:

GitFilter

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) or serveRegex(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.
