javax.sound.midi.MidiFileFormat

A MidiFileFormat object encapsulates a MIDI file's type, as well as its length and timing information.

A MidiFileFormat object can include a set of properties. A property is a pair of key and value: the key is of type String, the associated property value is an arbitrary object. Properties specify additional informational meta data (like a author, or copyright). Properties are optional information, and file reader and file writer implementations are not required to provide or recognize properties.

The following table lists some common properties that should be used in implementations:

MIDI File Format Properties

Property key Value type Description

"author" String name of the author of this file

"title" String title of this file

"copyright" String copyright message

"date" Date date of the recording or release

"comment" String an arbitrary text

->midi-file-formatclj

(->midi-file-format type division-type resolution bytes microseconds)
(->midi-file-format type division-type resolution bytes microseconds properties)

Constructor.

Construct a MidiFileFormat with a set of properties.

type - the MIDI file type (0, 1, or 2) - int division-type - the timing division type (PPQ or one of the SMPTE types) - float resolution - the timing resolution - int bytes - the length of the MIDI file in bytes, or UNKNOWN_LENGTH if not known - int microseconds - the duration of the file in microseconds, or UNKNOWN_LENGTH if not known - long properties - a Map<String,Object> object with properties - java.util.Map

Constructor.

Construct a MidiFileFormat with a set of properties.

type - the MIDI file type (0, 1, or 2) - `int`
division-type - the timing division type (PPQ or one of the SMPTE types) - `float`
resolution - the timing resolution - `int`
bytes - the length of the MIDI file in bytes, or UNKNOWN_LENGTH if not known - `int`
microseconds - the duration of the file in microseconds, or UNKNOWN_LENGTH if not known - `long`
properties - a Map<String,Object> object with properties - `java.util.Map`

get-byte-lengthclj

(get-byte-length this)

Obtains the length of the MIDI file, expressed in 8-bit bytes.

returns: the number of bytes in the file, or UNKNOWN_LENGTH if not known - int

Obtains the length of the MIDI file, expressed in 8-bit bytes.

returns: the number of bytes in the file, or UNKNOWN_LENGTH if not known - `int`
raw docstring

get-division-typeclj

(get-division-type this)

Obtains the timing division type for the MIDI file.

returns: the division type (PPQ or one of the SMPTE types) - float

Obtains the timing division type for the MIDI file.

returns: the division type (PPQ or one of the SMPTE types) - `float`
raw docstring

get-microsecond-lengthclj

(get-microsecond-length this)

Obtains the length of the MIDI file, expressed in microseconds.

returns: the file's duration in microseconds, or UNKNOWN_LENGTH if not known - long

Obtains the length of the MIDI file, expressed in microseconds.

returns: the file's duration in microseconds, or UNKNOWN_LENGTH if not known - `long`
raw docstring

get-propertyclj

(get-property this key)

Obtain the property value specified by the key. The concept of properties is further explained in the class description.

If the specified property is not defined for a particular file format, this method returns null.

key - the key of the desired property - java.lang.String

returns: the value of the property with the specified key, or null if the property does not exist. - java.lang.Object

Obtain the property value specified by the key.
 The concept of properties is further explained in
 the class description.

 If the specified property is not defined for a
 particular file format, this method returns
 null.

key - the key of the desired property - `java.lang.String`

returns: the value of the property with the specified key,
         or null if the property does not exist. - `java.lang.Object`
raw docstring

get-resolutionclj

(get-resolution this)

Obtains the timing resolution for the MIDI file. If the division type is PPQ, the resolution is specified in ticks per beat. For SMTPE timing, the resolution is specified in ticks per frame.

returns: the number of ticks per beat (PPQ) or per frame (SMPTE) - int

Obtains the timing resolution for the MIDI file.
 If the division type is PPQ, the resolution is specified in ticks per beat.
 For SMTPE timing, the resolution is specified in ticks per frame.

returns: the number of ticks per beat (PPQ) or per frame (SMPTE) - `int`
raw docstring

get-typeclj

(get-type this)

Obtains the MIDI file type.

returns: the file's type (0, 1, or 2) - int

Obtains the MIDI file type.

returns: the file's type (0, 1, or 2) - `int`
raw docstring

propertiesclj

(properties this)

Obtain an unmodifiable map of properties. The concept of properties is further explained in the class description.

returns: a Map<String,Object> object containing all properties. If no properties are recognized, an empty map is returned. - java.util.Map<java.lang.String,java.lang.Object>

Obtain an unmodifiable map of properties.
 The concept of properties is further explained in
 the class description.

returns: a Map<String,Object> object containing
         all properties. If no properties are recognized, an empty map is
         returned. - `java.util.Map<java.lang.String,java.lang.Object>`
