JRE 8 rt.jar - javax.* Package Source Code

JRE 8 rt.jar is the JAR file for JRE 8 RT (Runtime) libraries. JRE (Java Runtime) 8 is the runtime environment included in JDK 8. JRE 8 rt.jar libraries are divided into 6 packages:

com.* - Internal Oracle and Sun Microsystems libraries
java.* - Standard Java API libraries.
javax.* - Extended Java API libraries.
jdk.* -  JDK supporting libraries.
org.* - Third party libraries.
sun.* - Old libraries developed by Sun Microsystems.

/**
 * Ports are simple lines for input or output of audio to or from audio devices.
 * Common examples of ports that act as source lines (mixer inputs) include the microphone,
 * line input, and CD-ROM drive.  Ports that act as target lines (mixer outputs) include the
 * speaker, headphone, and line output.  You can access port using a <code>{@link Port.Info}</code>
 * object.

     * The <code>Port.Info</code> class extends <code>{@link Line.Info}</code>
     * with additional information specific to ports, including the port's name
     * and whether it is a source or a target for its mixer.
     * 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>{@link Mixer#getSourceLineInfo getSourceLineInfo}</code> and
     * <code>{@link Mixer#getTargetLineInfo getTargetLineInfo}</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.
