Constructor Detail

JointModelState

public JointModelState(VoiceSplittingModelState voice,
               BeatTrackingModelState beat,
               MetricalModelState hierarchy)

Create a new JointModelState with the given constituent states.

Parameters:

voice - voiceState

beat - beatState

hierarchy - hierarchyState

Parameters:

h - hierarchyState

Method Detail

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.

handleIncoming

public java.util.TreeSet<JointModelState> 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:

handleIncoming in class MidiModelState

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<JointModelState> 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 MidiModelState

Returns:

A TreeSet of the MidiModelStates we've transitioned into.

getVoiceState

public VoiceSplittingModelState getVoiceState()

Get the VoiceSplittingModelState currently in this JointModelState.

Returns:

voiceState

getBeatState

public BeatTrackingModelState getBeatState()

Get the BeatTrackingModelState currently in this JointModelState.

Returns:

beatState

getHierarchyState

public MetricalModelState getHierarchyState()

Get the HierarchyModelState currently in this JointModelState.

Returns:

hierarchyState

compareTo

public int compareTo(JointModelState o)

Specified by:

compareTo in interface java.lang.Comparable<JointModelState>

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
