All Implemented Interfaces:

Shrink<BigInteger>

public class BigIntegerGenerator
extends IntegralGenerator<BigInteger>

Produces values of type BigInteger.

With no additional configuration, the generated values are chosen from a range with a magnitude decided by GenerationStatus.size().

Method Detail

configure

public void configure(InRange range)

Tells this generator to produce values within a specified minimum and/or maximum inclusive, with uniform distribution.

If an endpoint of the range is not specified, its value takes on a magnitude influenced by GenerationStatus.size().

Parameters:

range - annotation that gives the range's constraints
