CallableGenerator

public CallableGenerator()

Method Details

generate

public Callable<V> generate(SourceOfRandomness random,
 GenerationStatus status)

Description copied from interface: Gen

Generates a value, possibly influenced by a source of randomness and metadata about the generation.

Parameters:

random - source of randomness to be used when generating the value

status - an object that can be used to influence the generated value. For example, generating lists can use the size method to generate lists with a given number of elements.

Returns:

the generated value

numberOfNeededComponents

public int numberOfNeededComponents()

Description copied from class: Generator

This is intended for use only by junit-quickcheck itself, and not by creators of custom generators.

Overrides:

numberOfNeededComponents in class Generator<Callable>

Returns:

how many component generators this generator needs
