      org.glassfish.grizzly.filterchain.TransportFilter

All Implemented Interfaces:

Filter

public class TransportFilter
extends BaseFilter

Transport Filter implementation, which should work with any Transport. This Filter tries to delegate I/O event processing to the Transport's specific transport Filter. If Transport doesn't have own implementation - uses common I/O event processing logic. TransportFilter could be set to work in 2 modes: stream or message. In stream mode, TransportFilter produces/consumes the socket channel directly. In message mode, TransportFilter represents Connection data as Buffer, using FilterChainContext.getMessage()}, FilterChainContext.setMessage(Object). For specific Transport, one mode could be more preferable than another. For example TCPNIOTransport works just in stream mode. UDPNIOTransport prefers message mode, but could also work in stream mode.
