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:

The types of MIDI message * that satisfy this criterion are channel voice, channel mode, system common, * and system real-time--in other words, everything except system exclusive * and meta-events. The <code>ShortMessage</code> class provides methods * for getting and setting the contents of the MIDI message. * <p> * A number of <code>ShortMessage</code> methods have integer parameters by which * you specify a MIDI status or data byte. If you know the numeric value, you * can express it directly. For system common and system real-time messages, * you can often use the corresponding fields of <code>ShortMessage</code>, such as * {@link #SYSTEM_RESET SYSTEM_RESET}. For channel messages, * the upper four bits of the status byte are specified by a command value and * the lower four bits are specified by a MIDI channel number. To * convert incoming MIDI data bytes that are in the form of Java's signed bytes, * you can use the <A HREF="MidiMessage.html#integersVsBytes">conversion code</A> * given in the <code>{@link MidiMessage}</code> class description. * * @see SysexMessage * @see MetaMessage * * @author David Rivas * @author Kara Kytle * @author Florian Bomers */ public class ShortMessage extends MidiMessage { // Status byte defines // System common messages /** * Status byte for MIDI Time Code Quarter Frame message (0xF1, or 241). * @see MidiMessage#getStatus */ public static final int MIDI_TIME_CODE = 0xF1; // 241 /** * Status byte for Song Position Pointer message (0xF2, or 242). * @see MidiMessage#getStatus */ public static final int SONG_POSITION_POINTER = 0xF2; // 242 /** * Status byte for MIDI Song Select message (0xF3, or 243). * @see MidiMessage#getStatus */ public static final int SONG_SELECT = 0xF3; // 243 /** * Status byte for Tune Request message (0xF6, or 246). * @see MidiMessage#getStatus */ public static final int TUNE_REQUEST = 0xF6; // 246 /** * Status byte for End of System Exclusive message (0xF7, or 247). * @see MidiMessage#getStatus */ public static final int END_OF_EXCLUSIVE = 0xF7; // 247 // System real-time messages /** * Status byte for Timing Clock message (0xF8, or 248). * @see MidiMessage#getStatus */ public static final int TIMING_CLOCK = 0xF8; // 248 /** * Status byte for Start message (0xFA, or 250). * @see MidiMessage#getStatus */ public static final int START = 0xFA; // 250 /** * Status byte for Continue message (0xFB, or 251). * @see MidiMessage#getStatus */ public static final int CONTINUE = 0xFB; // 251 /** * Status byte for Stop message (0xFC, or 252). * @see MidiMessage#getStatus */ public static final int STOP = 0xFC; //252 /** * Status byte for Active Sensing message (0xFE, or 254). * @see MidiMessage#getStatus */ public static final int ACTIVE_SENSING = 0xFE; // 254 /** * Status byte for System Reset message (0xFF, or 255). * @see MidiMessage#getStatus */ public static final int SYSTEM_RESET = 0xFF; // 255 // Channel voice message upper nibble defines /** * Command value for Note Off message (0x80, or 128) */ public static final int NOTE_OFF = 0x80; // 128 /** * Command value for Note On message (0x90, or 144) */ public static final int NOTE_ON = 0x90; // 144 /** * Command value for Polyphonic Key Pressure (Aftertouch) message (0xA0, or 160) */ public static final int POLY_PRESSURE = 0xA0; // 160 /** * Command value for Control Change message (0xB0, or 176) */ public static final int CONTROL_CHANGE = 0xB0; // 176 /** * Command value for Program Change message (0xC0, or 192) */ public static final int PROGRAM_CHANGE = 0xC0; // 192 /** * Command value for Channel Pressure (Aftertouch) message (0xD0, or 208) */ public static final int CHANNEL_PRESSURE = 0xD0; // 208 /** * Command value for Pitch Bend message (0xE0, or 224) */ public static final int PITCH_BEND = 0xE0; // 224 // Instance variables /** * Constructs a new <code>ShortMessage</code>.
