com.ergotech.vib.servers.ArrayDataSource

public class ArrayDataSource
extends SimpleDataSource

This generates ArrayValueObjects for testing VIB components. It is also an example of implementing VIB data sources which are ArrayValueObjects. Each ArrayValueObject will have n elements (set by the setElements method) and contains a timestamp and a random data value for each element (the data range is set by setMinValue and setMaxValue).
