All Implemented Interfaces:

FilterChain

public final class AtmosphereFilterChain
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.
