Class Transport

java.lang.Object
  jcifs.util.transport.Transport

All Implemented Interfaces:

Runnable

Direct Known Subclasses:

SmbTransport

public abstract class Transport
extends Object
implements 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.
