Class MidiMessage

protected byte[] data

MIDI message data.

protected int length

The total length of the MIDI message.

protected MidiMessage(byte[] data)

MidiMessage contructor.

Parameters:

data - a valid MIDI message

public abstract Object clone()

This method may be called to create a new copy of the Object. The typical behavior is as follows:

• o == o.clone() is false
• o.getClass() == o.clone().getClass() is true
• o.equals(o) is true

However, these are not strict requirements, and may be violated if necessary. Of the three requirements, the last is the most commonly violated, particularly if the subclass does not override Object.equals(Object).

If the Object you call clone() on does not implement Cloneable (which is a placeholder interface), then a CloneNotSupportedException is thrown. Notice that Object does not implement Cloneable; this method exists as a convenience for subclasses that do.

Object's implementation of clone allocates space for the new Object using the correct class, without calling any constructors, and then fills in all of the new field values with the old field values. Thus, it is a shallow copy. However, subclasses are permitted to make a deep copy.

All array types implement Cloneable, and override this method as follows (it should never fail):

 public Object clone()
 {
   try
     {
       super.clone();
     }
   catch (CloneNotSupportedException e)
     {
       throw new InternalError(e.getMessage());
     }
 }
 

Overrides:

clone in interface Object

Returns:

a copy of the Object

public int getLength()

Get the length of the MIDI message.

Returns:

the length of the MIDI messsage

public byte[] getMessage()

Get the MIDI message data.

Returns:

an array containing the MIDI message data

public int getStatus()

Get the status byte of the MIDI message (as an int)

Returns:

the status byte of the MIDI message (as an int), or zero if the message length is zero.

protected void setMessage(byte[] data,
                          int length)

Parameters:

data - The complete MIDI message.

length - The length of the MIDI message.

Throws:

InvalidMidiDataException - Thrown when the MIDI message is invalid.
