 boolean nullable)

Method Details

generateNonNullValue

protected abstract T generateNonNullValue(Random random)

getMin

protected T getMin()

getMax

protected T getMax()

min

public NumberAsStringGeneratorSpec<T> min(T min)

Description copied from interface: NumberGeneratorSpec

Lower bound for the random number generator.

Specified by:

min in interface NumberAsStringGeneratorSpec<T extends Number>

Specified by:

min in interface NumberGeneratorSpec<T extends Number>

Parameters:

min - lower bound (inclusive)

Returns:

spec builder

max

public NumberAsStringGeneratorSpec<T> max(T max)

Description copied from interface: NumberGeneratorSpec

Upper bound for the random number generator.

Specified by:

max in interface NumberAsStringGeneratorSpec<T extends Number>

Specified by:

max in interface NumberGeneratorSpec<T extends Number>

Parameters:

max - upper bound (inclusive)

Returns:

spec builder

nullable

public NumberAsStringGeneratorSpec<T> nullable()

Description copied from interface: NullableGeneratorSpec

Indicates that null value can be generated.

Specified by:

nullable in interface NullableGeneratorSpec<T extends Number>

Specified by:

nullable in interface NumberAsStringGeneratorSpec<T extends Number>

Specified by:

nullable in interface NumberGeneratorSpec<T extends Number>

Overrides:

nullable in class AbstractGenerator<T extends Number>

Returns:

spec builder

nullable

public NumberAsStringGeneratorSpec<T> nullable(boolean isNullable)

Overrides:

nullable in class AbstractGenerator<T extends Number>

range

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

Description copied from interface: NumberGeneratorSpec

Range for the random number generator

Specified by:

range in interface NumberAsStringGeneratorSpec<T extends Number>

Specified by:

range in interface NumberGeneratorSpec<T extends Number>

Parameters:

min - lower bound (inclusive)

max - upper bound (inclusive)

Returns:

spec builder

generate

public final T generate(Random random)

Description copied from interface: Generator

Returns a generated value.

If this method produces random data, the data needs to be generated using the provided Random instance. This ensures generated values are reproducible for a given seed value.

Specified by:

generate in interface Generator<T extends Number>

Parameters:

random - provider for generating random values

Returns:

generated value or null if value is nullable, could not be generated, or generation is delegated to the engine
