All Implemented Interfaces:

java.lang.Runnable

Direct Known Subclasses:

SmbTransport

public abstract class Transport
extends java.lang.Object
implements java.lang.Runnable

This class simplifies communication for protocols that support multiplexing requests. It encapsulates a stream and some protocol knowledge (provided by a concrete subclass) so that connecting, disconnecting, sending, and receiving can be syncronized properly. Apparatus is provided to send and receive requests concurrently.
