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.
JAR File Information:

They include * not only the standard MIDI messages that a synthesizer can respond to, but also * "meta-events" that can be used by sequencer programs. There are meta-events * for such information as lyrics, copyrights, tempo indications, time and key * signatures, markers, etc. For more information, see the Standard MIDI Files 1.0 * specification, which is part of the Complete MIDI 1.0 Detailed Specification * published by the MIDI Manufacturer's Association * (<a href = http://www.midi.org>http://www.midi.org</a>). * <p> * The base <code>MidiMessage</code> class provides access to three types of * information about a MIDI message: * <ul> * <li>The messages's status byte</li> * <li>The total length of the message in bytes (the status byte plus any data bytes)</li> * <li>A byte array containing the complete message</li> * </ul> * * <code>MidiMessage</code> includes methods to get, but not set, these values. * Setting them is a subclass responsibility. * <p> * <a name="integersVsBytes"></a> * The MIDI standard expresses MIDI data in bytes. However, because * Java<sup>TM</sup> uses signed bytes, the Java Sound API uses integers * instead of bytes when expressing MIDI data. For example, the * {@link #getStatus()} method of * <code>MidiMessage</code> returns MIDI status bytes as integers. If you are * processing MIDI data that originated outside Java Sound and now * is encoded as signed bytes, the bytes can * can be converted to integers using this conversion: * <center>{@code int i = (int)(byte & 0xFF)}</center> * <p> * If you simply need to pass a known MIDI byte value as a method parameter, * it can be expressed directly as an integer, using (for example) decimal or * hexadecimal notation. For instance, to pass the "active sensing" status byte * as the first argument to ShortMessage's * {@link ShortMessage#setMessage(int) setMessage(int)} * method, you can express it as 254 or 0xFE. * * @see Track * @see Sequence * @see Receiver * * @author David Rivas * @author Kara Kytle */ public abstract class MidiMessage implements Cloneable { // Instance variables /** * The MIDI message data.
