com.pholser.junit.quickcheck.generator.java.math.BigDecimalGenerator

public class BigDecimalGenerator
extends Generator<BigDecimal>

Produces values for theory parameters of type BigDecimal.

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 (inclusive) and/or maximum (exclusive), 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

Throws:

NumberFormatException - if the range's values cannot be converted to BigDecimal

IllegalArgumentException - if the range's values specify a nonsensical range

configure

public void configure(Precision configuration)

Tells this generator to produce values that have a specified scale.

With no precision constraint and no min/max constraint, the scale of the generated values is unspecified.

Otherwise, the scale of the generated values is set as max(0, precision.scale, range.min.scale, range.max.scale).

Parameters:

configuration - annotation that gives the desired scale of the generated values

generate

public BigDecimal generate(SourceOfRandomness random,
                           GenerationStatus status)
