  use MIDI::Track;

  $End_Excl = MIDI::XML::EndOfExclusive->new();
  $End_Excl->delta(384);
  $End_Excl->data(pack('C*',65,16,66,18,64,0,127,0,65,247));
  @event = $End_Excl->as_event();
  $midi_track = MIDI::Track->new();

DESCRIPTION

MIDI::XML::EndOfExclusive is a class encapsulating MIDI End Of Exclusive messages. An End Of Exclusive message includes either a delta time or absolute time as implemented by MIDI::XML::Message and the MIDI End Of Exclusive event encoded as follows:

111101111 data 11110111

EXPORT

None.

METHODS AND ATTRIBUTES

$End_Excl = MIDI::XML::EndOfExclusive->new();

This creates a new MIDI::XML::EndOfExclusive object.

$End_Excl = MIDI::XML::EndOfExclusive->new($event);

Creates a new EndOfExclusive object initialized with the values of a MIDI::Event sysex_f7 array.

$delta_time = $End_Excl->delta() or $End_Excl->delta($delta_time);

Returns the message time as a delta time or undef if it is an absolute time. Optionally sets the message time to the specified delta time. To avoid contradictory times, the absolute time is set to undef when a delta time is set.

This functionality is provided by the MIDI::XML::Message base class.

$absolute_time = $End_Excl->absolute() or $End_Excl->absolute($absolute_time);

Returns the message time as an absolute time or undef if it is a delta time. Optionally sets the message time to the specified absolute time. To avoid contradictory times, the delta time is set to undef when an absolute time is set.

This functionality is provided by the MIDI::XML::Message base class.

$time = $End_Excl->time();

Returns the message time, absolute or delta, whichever was last set.

This functionality is provided by the MIDI::XML::Message base class.

$data = $End_Excl->data() or $End_Excl->data($data);

Returns and optionally sets the data content.

@event = $End_Excl->as_event();

Returns a MIDI::Event sysex_f7 array initialized with the values of the End Of Exclusive object. MIDI::Event does not expect absolute times and will interpret them as delta times. Calling this method when the time is absolute will not generate a warning or error but it is unlikely that the results will be satisfactory.

@xml = $End_Excl->as_MidiXML();

Returns an array of elements formatted according to the MidiXML DTD. These elements may be assembled by track into entire documents with the following suggested DOCTYPE declaration:

        <!DOCTYPE MIDI PUBLIC
                "-//Recordare//DTD MusicXML 0.7 MIDI//EN"
                "http://www.musicxml.org/dtds/midixml.dtd">
