Method Details

generate

public T 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
