FromFileVoiceSplittingModelState

public FromFileVoiceSplittingModelState(EventParser ep)
                                 throws javax.sound.midi.InvalidMidiDataException

Creates a new object, generating voices directly from the EventParser.getGoldStandardVoices() method.

Parameters:

ep - The EventParser we will get the gold standard voices from.

Throws:

javax.sound.midi.InvalidMidiDataException

Method Detail

getVoices

public java.util.List<Voice> getVoices()

Description copied from class: VoiceSplittingModelState

Gets the Voices which are contained by this state currently.

Specified by:

getVoices in class VoiceSplittingModelState

Returns:

A List of the Voices contained by this State.

handleIncoming

public java.util.TreeSet<FromFileVoiceSplittingModelState> handleIncoming(java.util.List<MidiNote> notes)

Description copied from class: MidiModelState

Return a TreeSet of all of the possible MidiModelStates which we could tansition into given the List of MidiNotes.

Specified by:

Parameters:

notes - A List of the MidiNotes on which we need to transition.

Returns:

A TreeSet of MidiModelStates which we've transitioned into.

close

public java.util.TreeSet<FromFileVoiceSplittingModelState> close()

Description copied from class: MidiModelState

Return a TreeSet of all of the possible MidiModelStates which we could tansition into when the input closes.

Specified by:

close in class VoiceSplittingModelState

Returns:

A TreeSet of the MidiModelStates we've transitioned into.

getScore

public double getScore()

Description copied from class: MidiModelState

Get the score of this MidiModelState. In general, a higher score reflects that a State is more likely given our prior knowledge. The natural ordering of MidiModelStates is based on this score value.

Specified by:

getScore in class MidiModelState

Returns:

The score of this MidiModelState.
