Package brave.spring.webmvc

Class DelegatingTracingFilter

java.lang.Object

brave.spring.webmvc.DelegatingTracingFilter

All Implemented Interfaces:

javax.servlet.Filter

public final class DelegatingTracingFilter
extends Object
implements javax.servlet.Filter

Similar to TracingFilter, except that it initializes from Spring.

DelegatingFilterProxy is similar, but it uses volatile references as it allows lazy initialization from doGet. This filter cannot do that anyway because ServletRequest.getServletContext() was added after servlet 2.5!
