Class AtmosphereFilterChain

  • All Implemented Interfaces:
    javax.servlet.FilterChain
    public final class AtmosphereFilterChain
extends java.lang.Object
implements javax.servlet.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.
