/**
 * The <code>ObexTransport</code> interface defines the underlying transport
 * connection which carries the OBEX protocol( such as TCP, RFCOMM device file
 * exposed by Bluetooth or USB in kernel, RFCOMM socket emulated in Android
 * platform, Irda). This interface provides an abstract layer to be used by the
 * <code>ObexConnection</code>. Each kind of medium shall have its own
 * implementation to wrap and follow the same interface.
 * <P>
 * See section 1.2.2 of IrDA Object Exchange Protocol specification.
 * <P>
 * Different kind of medium may have different construction - for example, the
 * RFCOMM device file medium may be constructed from a file descriptor or simply
 * a string while the TCP medium usually from a socket.
