Class StreamClientImpl

java.lang.Object
  org.teleal.cling.transport.impl.StreamClientImpl

All Implemented Interfaces:

StreamClient

public class StreamClientImpl
extends Object
implements StreamClient

Default implementation based on the JDK's HttpURLConnection.

This class works around a serious design issue in the SUN JDK, so it will not work on any JDK that doesn't offer the sun.net.www.protocol.http.HttpURLConnection implementation.
