Constructor Detail

WaveformImpl

public WaveformImpl(double[] time,
                    double[] value)

Constructs waveform from time and value arrays. They must have the same length.

Parameters:

time - time array

value - value array

Throws:

java.lang.IllegalArgumentException - if time and value arrays have different size

Method Detail

getNumEvents

public int getNumEvents()

Method to return the number of events in this signal. This is the number of events along the horizontal axis, usually "time".

Specified by:

getNumEvents in interface Waveform

Returns:

the number of events in this signal.

getEvent

public void getEvent(int index,
                     double[] result)

Method to return the value of this signal at a given event index.

Specified by:

getEvent in interface Waveform

Parameters:

index - the event index (0-based).

result - double array of length 3 to return (time, lowValue, highValue) If this signal is not a basic signal, return 0 and print an error message.
