(See the discussion in the <code>MidiMessage</code> class description.) The Standard MIDI Files specification defines various types of meta-events, such as sequence number, lyric, cue point, and set tempo. There are also 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> When data is being transported using MIDI wire protocol, a <code><A HREF="../../../javax/sound/midi/ShortMessage.html"><CODE>ShortMessage</CODE></A></code> with the status value <code>0xFF</code> represents a system reset message. In MIDI files, this same status value denotes a <code>MetaMessage</code>. The types of meta-message are distinguished from each other by the first byte that follows the status byte <code>0xFF</code>. The subsequent bytes are data bytes. As with system exclusive messages, there are an arbitrary number of data bytes, depending on the type of <code>MetaMessage</code>.<P><DL><DT><B>See Also: </B><DD><A HREF="../../../javax/sound/midi/MetaEventListener.html"><CODE>MetaEventListener</CODE></A></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Field Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static int</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/sound/midi/MetaMessage.html#META">META</A></B></CODE><BR> Status byte for <code>MetaMessage</code> (0xFF, or 255), which is used in MIDI files.</TD></TR></TABLE> <A NAME="fields_inherited_from_class_javax.sound.midi.MidiMessage"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Fields inherited from class javax.sound.midi.<A HREF="../../../javax/sound/midi/MidiMessage.html">MidiMessage</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../../javax/sound/midi/MidiMessage.html#data">data</A>, <A HREF="../../../javax/sound/midi/MidiMessage.html#length">length</A></CODE></TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Constructor Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> </CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/sound/midi/MetaMessage.html#MetaMessage()">MetaMessage</A></B>()</CODE><BR> Constructs a new <code>MetaMessage</code>.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>protected </CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/sound/midi/MetaMessage.html#MetaMessage(byte[])">MetaMessage</A></B>(byte[] data)</CODE><BR> Constructs a new <code>MetaMessage</code>.</TD></TR></TABLE> <!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../java/lang/Object.html">Object</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/sound/midi/MetaMessage.html#clone()">clone</A></B>()</CODE><BR> Creates a new object of the same class and with the same contents as this object.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> byte[]</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/sound/midi/MetaMessage.html#getData()">getData</A></B>()</CODE><BR> Obtains a copy of the data for the meta message.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> int</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/sound/midi/MetaMessage.html#getType()">getType</A></B>()</CODE><BR> Obtains the type of the <code>MetaMessage<code>.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/sound/midi/MetaMessage.html#setMessage(int, byte[], int)">setMessage</A></B>(int type, byte[] data, int length)</CODE><BR> Sets the message parameters for a <code>MetaMessage</code>.</TD></TR>⌨️ 快捷键说明
