Constructor Details

DoubleGenerator

public DoubleGenerator()

DoubleGenerator

public DoubleGenerator(GeneratorContext context)

Method Details

apiMethod

public String apiMethod()

Description copied from class: AbstractGenerator

Returns the public API method name of the generator spec. The returned name is used for reporting validation errors.

Specified by:

apiMethod in class AbstractGenerator<Double>

Returns:

spec name if defined, or null otherwise

min

public DoubleGenerator min(Double min)

Description copied from class: AbstractRandomComparableNumberGeneratorSpec

Specifies the lower bound.

If the specified min value is greater than or equal to the current max value, the max value will be updated to a value higher than the given min.

Specified by:

min in interface DoubleSpec

Specified by:

min in interface NumberAsGeneratorSpec<Double>

Specified by:

min in interface NumberGeneratorSpec<Double>

Specified by:

min in interface NumberSpec<Double>

Overrides:

min in class AbstractRandomComparableNumberGeneratorSpec<Double>

Parameters:

min - lower bound (inclusive)

Returns:

spec builder

max

public DoubleGenerator max(Double max)

Description copied from class: AbstractRandomComparableNumberGeneratorSpec

Specifies the upper bound.

If the specified max value is less than or equal to the current min value, the min value will be updated to a value lower than the given max.

Specified by:

max in interface DoubleSpec

Specified by:

max in interface NumberAsGeneratorSpec<Double>

Specified by:

max in interface NumberGeneratorSpec<Double>

Specified by:

max in interface NumberSpec<Double>

Overrides:

max in class AbstractRandomComparableNumberGeneratorSpec<Double>

Parameters:

max - upper bound (inclusive)

Returns:

spec builder

range

public DoubleGenerator range(Double min,
 Double max)

Description copied from interface: NumberGeneratorSpec

Specifies the range for the generated number.

This method can be invoked multiple times to specify several ranges, for example, the following will generate a random value within [10-15] or [20-25]:

   ints().range(10, 15).range(20, 25)
 

Note: this method has higher precedence than NumberGeneratorSpec.min(Number) and NumberGeneratorSpec.max(Number). For example, the following will generate a number within [1, 5]:

   ints().range(1, 5).min(95).max(99)
 

Specified by:

range in interface DoubleSpec

Specified by:

range in interface NumberAsGeneratorSpec<Double>

Specified by:

range in interface NumberGeneratorSpec<Double>

Specified by:

range in interface NumberSpec<Double>

Overrides:

range in class AbstractRandomComparableNumberGeneratorSpec<Double>

Parameters:

min - lower bound (inclusive)

max - upper bound (inclusive)

Returns:

spec builder

nullable

public DoubleGenerator nullable()

Description copied from interface: NullableGeneratorSpec

Indicates that null value can be generated.

Specified by:

nullable in interface DoubleSpec

Specified by:

nullable in interface NullableGeneratorSpec<Double>

Specified by:

nullable in interface NumberAsGeneratorSpec<Double>

Specified by:

nullable in interface NumberGeneratorSpec<Double>

Specified by:

nullable in interface NumberSpec<Double>

Specified by:

nullable in interface ValueSpec<Double>

Overrides:

nullable in class AbstractRandomNumberGeneratorSpec<Double>

Returns:

spec builder

nullable

public DoubleGenerator nullable(boolean isNullable)

Overrides:

nullable in class AbstractRandomNumberGeneratorSpec<Double>

tryGenerateNonNull

protected Double tryGenerateNonNull(Random random)

Description copied from class: AbstractGenerator

Makes the best effort to return a non-null value. However, in certain cases this method will produce a null.

Specified by:

tryGenerateNonNull in class AbstractGenerator<Double>

Parameters:

random - for generating the value

Returns:

generated value, either a null or non-null
