Class SysexMessage

public static final int SPECIAL_SYSTEM_EXCLUSIVE

Field Value:

247

public static final int SYSTEM_EXCLUSIVE

Field Value:

240

public SysexMessage()

Create a default valid system exclusive message. The official specs don't specify what message is to be created. Our implementation creates an empty system exclusive message.

protected SysexMessage(byte[] data)

Create a SysexMessage 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 byte.

Returns:

the message data, not including the status byte

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

Set the sysex message. The first data byte (status) must be 0xF0 or 0xF7.

Overrides:

setMessage in interface MidiMessage

Parameters:

data - the message data

length - the length of the message data

Throws:

InvalidMidiDataException - if the status byte is not 0xF0 or 0xF7

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

Set the sysex message. status must be either 0xF0 or 0xF7.

Parameters:

status - the sysex statys byte (0xF0 or 0xF7)

data - the message data

length - the length of the message data

Throws:

InvalidMidiDataException - if status is not 0xF0 or 0xF7
