Field Details

ipoltable

@Opt
protected final @Opt Map<Event,String> ipoltable

The event parameters "interpolation mode", if present.

predecTime

protected double predecTime

The onset time point of the earlier event currently under visit.

currentTime

protected double currentTime

The onset time point of the later event currently under visit.

ipol

protected boolean ipol

Whether the earlier event has a "interpolate" flag set in its tscore source.

Constructor Details

Process

public Process(Iterable<Event> it,
 @Opt
 @Opt Map<Event,String> ipoltable)

Only constructur, sets up all parameters for the execution by Iterators.Pairwise.process().

Parameters:

it - iterable, normally related to one single voice, e.g. from voiceEvents(v, range_respectingDomainOrder(rat2tp)) or sim.

ipoltable - gives for each event the interpolation mode to the subsequent value, in a symbolic text form.

Method Details

time

protected double time(Event e)

Get the onset time of the event according to the calendearic time data in the score.

first

public void first(Event e)

Description copied from class: eu.bandm.tools.util.java.Iterators.Pairwise

Can be overridden by the user to visit the very first element before the first pair is visited by Iterators.Pairwise.pairwise(Object,Object).

Overrides:

first in class Iterators.Pairwise<Event>

pairwise

public void pairwise(Event predec,
 Event current)

Must be overridden by the user to visit the define what to do with each pair of adjacent elements. These are visited in the sequential order of the underlying Iterator. On Execution, that has berformed a Iterator.next(), so that it "points" (e.g. with its Iterator.hasNext() to the successor of the later of both visited elements. Here: prepare the registers ipol and currentTime.
