Class FilterChainInvocation

java.lang.Object

com.google.inject.servlet.FilterChainInvocation

All Implemented Interfaces:

javax.servlet.FilterChain

class FilterChainInvocation
extends java.lang.Object
implements javax.servlet.FilterChain

A Filter chain impl which basically passes itself to the "current" filter and iterates the chain on doFilter(). Modeled on something similar in Apache Tomcat. Following this, it attempts to dispatch to guice-servlet's registered servlets using the ManagedServletPipeline. And the end, it proceeds to the web.xml (default) servlet filter chain, if needed.
