MidiFileReader | abstract public class MidiFileReader (Code) | | A MidiFileReader supplies MIDI file-reading services. Classes implementing this
interface can parse the format information from one or more types of
MIDI file, and can produce a Sequence object from files of these types.

getMidiFileFormat | abstract public MidiFileFormat getMidiFileFormat(InputStream stream) throws InvalidMidiDataException, IOException(Code) | | Obtains the MIDI file format of the input stream provided. The stream must
point to valid MIDI file data. In general, MIDI file readers may
need to read some data from the stream before determining whether they
support it. These parsers must
be able to mark the stream, read enough data to determine whether they
support the stream, and, if not, reset the stream's read pointer to its original
position. If the input stream does not support this, this method may fail
with an IOException .
Parameters: stream - the input stream from which file format information should beextracted a MidiFileFormat object describing the MIDI file format throws: InvalidMidiDataException - if the stream does not point to valid MIDIfile data recognized by the system throws: IOException - if an I/O exception occurs See Also: InputStream.markSupported See Also: InputStream.mark |
getMidiFileFormat | abstract public MidiFileFormat getMidiFileFormat(URL url) throws InvalidMidiDataException, IOException(Code) | | Obtains the MIDI file format of the URL provided. The URL must
point to valid MIDI file data.
Parameters: url - the URL from which file format information should beextracted a MidiFileFormat object describing the MIDI file format throws: InvalidMidiDataException - if the URL does not point to valid MIDIfile data recognized by the system throws: IOException - if an I/O exception occurs |
getMidiFileFormat | abstract public MidiFileFormat getMidiFileFormat(File file) throws InvalidMidiDataException, IOException(Code) | | Obtains the MIDI file format of the File provided.
The File must point to valid MIDI file data.
Parameters: file - the File from which file format information should beextracted a MidiFileFormat object describing the MIDI file format throws: InvalidMidiDataException - if the File does not point to valid MIDIfile data recognized by the system throws: IOException - if an I/O exception occurs |
getSequence | abstract public Sequence getSequence(InputStream stream) throws InvalidMidiDataException, IOException(Code) | | Obtains a MIDI sequence from the input stream provided. The stream must
point to valid MIDI file data. In general, MIDI file readers may
need to read some data from the stream before determining whether they
support it. These parsers must
be able to mark the stream, read enough data to determine whether they
support the stream, and, if not, reset the stream's read pointer to its original
position. If the input stream does not support this, this method may fail
with an IOException.
Parameters: stream - the input stream from which the Sequence should beconstructed a Sequence object based on the MIDI file data containedin the input stream. throws: InvalidMidiDataException - if the stream does not point to valid MIDIfile data recognized by the system throws: IOException - if an I/O exception occurs See Also: InputStream.markSupported See Also: InputStream.mark |
getSequence | abstract public Sequence getSequence(URL url) throws InvalidMidiDataException, IOException(Code) | | Obtains a MIDI sequence from the URL provided. The URL must
point to valid MIDI file data.
Parameters: url - the URL for which the Sequence should beconstructed a Sequence object based on the MIDI file data pointedto by the URL throws: InvalidMidiDataException - if the URL does not point to valid MIDIfile data recognized by the system throws: IOException - if an I/O exception occurs |
getSequence | abstract public Sequence getSequence(File file) throws InvalidMidiDataException, IOException(Code) | | Obtains a MIDI sequence from the File provided. The File must
point to valid MIDI file data.
Parameters: file - the File from which the Sequence should beconstructed a Sequence object based on the MIDI file data pointedto by the File throws: InvalidMidiDataException - if the File does not point to valid MIDIfile data recognized by the system throws: IOException - if an I/O exception occurs |
