In the document enumeration example, the parameter we want to vary contains
a numeric value, so our first implementation of the PayloadSource interface is
a class to generate numeric payloads. This class allows us to specify the range
of numbers we want to test:
class PSNumbers implements PayloadSource
{
int from, to, step, current;
PSNumbers(int from, int to, int step)
{
this.from = from;
this.to = to;
this.step = step;
reset();
}
public boolean nextPayload()
{
current += step;
return current
