By definition, a port acts as either a source or a target to its mixer, but not both. (Audio input ports are sources; audio output ports are targets.) <p> To learn what ports are available, you can retrieve port info objects through the <code><A HREF="../../../javax/sound/sampled/Mixer.html#getSourceLineInfo()"><CODE>getSourceLineInfo</CODE></A></code> and <code><A HREF="../../../javax/sound/sampled/Mixer.html#getTargetLineInfo()"><CODE>getTargetLineInfo</CODE></A></code> methods of the <code>Mixer</code> interface. Instances of the <code>Port.Info</code> class may also be constructed and used to obtain lines matching the parameters specified in the <code>Port.Info</code> object.<P><DL><DT><B>Since:
