Script

The script creates an event signal with text events for the state chart.

//-recjs (keep this line)
// generator   : Record generator (de.toem.impulse.samples.ISingleDomainRecordGenerator)
// file        : File object of the executed recJs file (java.io.File)
// p0..p9      : Parameters from the reader configuration (java.lang.String)
// progress    : Progress control (de.toem.impulse.cells.ports.IPortProgress)
// console     : Console output (de.toem.impulse.scripting.IScriptConsole) 

// Init the record
generator.initRecord("Example Record",TimeBase.ms);

 
// We forget the input and create a record with scopes and some signals
var signals  = generator.addScope(null, "Signals");
var intsig = generator.addSignal(signals, "Sin", "", ProcessType.Discrete, SignalType.Integer, SignalDescriptor.DEFAULT);
var event = generator.addSignal(signals, "Events", "", ProcessType.Discrete, SignalType.Event, new SignalDescriptor(ISample.CONTENT_EVENT,ISample.FORMAT_TEXT));


// We start at 0 ns
var t = 0; // 0 ns
generator.open(t);

// int signal
var writer /*:IIntegerSamplesWriter:*/ = generator.getWriter(intsig);
writer.writeInt(t, false, 0);
t=14000;
writer.writeInt(t, false, 0);
for (; t < 94000; t ++) {

    // write time as integer
    writer.writeInt(t, false,  (100 * Math.sin(t/1000.0)));
}
writer.writeInt(t, false, 0);
writer.writeInt(100000, false, 0);


// struct signal
writer /*:IEventSamplesWriter:*/ = generator.getWriter(event);


writer.write(20, false, "dummy");
writer.write(2000, false, "onOff");
writer.write(18000, false, "pedestrianRequest");
writer.write(60000, false, "pedestrianRequest");
writer.write(61000, false, "pedestrianRequest");
writer.write(80000, false, "pedestrianRequest");
writer.write(90000, false, "onOff");


generator.close(100000);
