Class MetaMessage

public static final int META

The META status code. Only valid for MIDI files, not the wire protocol.

Field Value:

255

public MetaMessage()

Create a default valid meta message. The official specs don't specify what message is to be created. For now, we create a zero length meta message with a type code of 0.

protected MetaMessage(byte[] data)

Create a MetaMessage object.

Parameters:

data - a complete system exclusive message

public 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 MidiMessage

Returns:

a copy of the Object

public byte[] getData()

Get the data for this message, not including the status, type, or length information.

Returns:

the message data, not including status, type or lenght info

public int getType()

Get the meta message type.

Returns:

the meta message type

public void setMessage(int type,
                       byte[] data,
                       int length)
            throws InvalidMidiDataException

Set the meta message.

Parameters:

type - the meta type byte (<32128)

data - the message data

length - the length of the message data

Throws:

InvalidMidiDataException - if this message is invalid
