Class SustainingInterpreter

public class SustainingInterpreter
extends Interpreter

SustainingInterpreter
An interpreter that interprets shape data, sustains that for some duration, then shuts it down.

Here is an example of defining interpret(), which turns ON an event, and interpretOff() which turns it OFF

        public double interpret(double playTime, double timeStretch, double dar[], Instrument ins) {
                // Turn note on (change this line for your needs)
                JMSL.out.println(this.getName() + " ON: " + dar[1] + " at time=" + playTime);

                // Schedule call to interpretOff.
                scheduleInterpretOff(playTime + (dar[3] * timeStretch), timeStretch, dar, ins );

                // Standard time interpretation.
                return playTime + (dar[0] * timeStretch);
        }

    // The noteoff you posted to SustainerFactory will call the method below when it is finished sustaining.
    public double interpretOff(double playTime, double timeStretch, double dar[], Instrument ins) {
        JMSL.out.println("   " + this.getName() + " OFF: " + dar[1] + " at time=" + playTime);
        return playTime;
    }
