Class ScopedFilter

java.lang.Object

org.ops4j.pax.web.service.spi.servlet.ScopedFilter

All Implemented Interfaces:

javax.servlet.Filter

public class ScopedFilter
extends Object
implements javax.servlet.Filter

Filter wrapper that can skip delegate's invocation if OsgiContextModel doesn't match.

This is important because of:

140.5 Registering Servlet Filters [...] Servlet filters are only applied to servlet requests if they are bound to the same Servlet Context Helper and the same Http Whiteboard implementation.

In Jetty we can configure the filters associated with invocation, but not in Undertow or Tomcat, which use fixed, static, final helper classes that can't be customized. Jetty wins here.
