org.apache.catalina.core.ApplicationFilterChain

All Implemented Interfaces:

HttpEventFilterChain

public final class ApplicationFilterChain
extends java.lang.Object
implements HttpEventFilterChain

Implementation of javax.servlet.FilterChain used to manage the execution of a set of filters for a particular request. When the set of defined filters has all been executed, the next call to doFilter() will execute the servlet's service() method itself.
