Class FilterChainImpl

java.lang.Object
  extended by com.sun.grizzly.http.servlet.FilterChainImpl
All Implemented Interfaces:
FilterChain

public final class FilterChainImpl
extends Object
implements FilterChain

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.
