Field Detail

measure

private Measure measure

The Measure of this metrical structure.

mostRecentTime

private long mostRecentTime

The time of the most recent note onset we've seen so far.

Constructor Detail

FromFileMetricalModelState

public FromFileMetricalModelState(TimeTracker tt)

Create a new FromFileBeatHierarchyState based on the given TimeTracker.

Parameters:

tt - The TimeTracker which we will grab the proper meter from.

FromFileMetricalModelState

private FromFileMetricalModelState(Measure measure,
                          long mostRecentTime)

Create a new FromFileHierarchyModelState and initialize the fileds as given. This is private as it is only used to clone this object from within the handleIncoming(List) method.

Parameters:

measure - measure

mostRecentTime - mostRecentTime

Method Detail

getMetricalMeasure

public Measure getMetricalMeasure()

Description copied from class: MetricalModelState

Gets the Measure which is contained by this state currently.

Specified by:

getMetricalMeasure in class MetricalModelState

Returns:

The measure contained by this state.

handleIncoming

public java.util.TreeSet<FromFileMetricalModelState> 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 MetricalModelState

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<FromFileMetricalModelState> 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 MetricalModelState

Returns:

A TreeSet of the MidiModelStates we've transitioned into.

deepCopy

public MetricalModelState deepCopy()

Description copied from class: MetricalModelState

Create a deep copy of this HierarchyModelState.

Specified by:

deepCopy in class MetricalModelState

Returns:

A deep copy of this HierarchyModelState.

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.

compareTo

public int compareTo(FromFileMetricalModelState o)

Specified by:

compareTo in interface java.lang.Comparable<FromFileMetricalModelState>
