AbstractRandomNumberGeneratorSpec

protected AbstractRandomNumberGeneratorSpec(GeneratorContext context,
                                            T min,
                                            T max,
                                            boolean nullable)

Method Detail

generateNonNullValue

protected abstract T generateNonNullValue(Random random)

getMin

protected T getMin()

getMax

protected T getMax()

min

public NumberGeneratorSpec<T> min(T min)

Description copied from interface: NumberGeneratorSpec

Lower bound for the random number generator.

Specified by:

min in interface NumberGeneratorSpec<T extends Number>

Parameters:

min - lower bound (inclusive)

Returns:

spec builder

max

public NumberGeneratorSpec<T> max(T max)

Description copied from interface: NumberGeneratorSpec

Upper bound for the random number generator.

Specified by:

max in interface NumberGeneratorSpec<T extends Number>

Parameters:

max - upper bound (exclusive)

Returns:

spec builder

range

public NumberGeneratorSpec<T> range(T min,
                                    T max)

Description copied from interface: NumberGeneratorSpec

Range for the random number generator

Specified by:

range in interface NumberGeneratorSpec<T extends Number>

Parameters:

min - lower bound (inclusive)

max - upper bound (exclusive)

Returns:

spec builder

nullable

public NumberGeneratorSpec<T> nullable()

Description copied from interface: NumberGeneratorSpec

Specifies the generated value can be null.

Specified by:

nullable in interface NumberGeneratorSpec<T extends Number>

Returns:

spec builder

generate

public final T generate(Random random)

Description copied from interface: Generator

Returns a generated value.

If the generated value is random, it needs to be generated using the given Random instance. This ensures the data is generated with the same seed value and allows random data to be reproduced by specifying the seed value.

Specified by:

generate in interface Generator<T extends Number>

Parameters:

random - provider for random values

Returns:

generated value

getHints

public GeneratedHints getHints()

Description copied from interface: Generator

Returns hints, including collection sizes and whether values are nullable.

Specified by:

getHints in interface Generator<T extends Number>

Returns:

generated hints
