Method Detail

generate

public Object generate(SourceOfRandomness random,
                       GenerationStatus status)

Description copied from class: Generator

Produces a value for a theory parameter.

A generator may raise an unchecked exception if some condition exists which would lead to a confusing generation -- for example, if a generator honored a range configuration, and the endpoints were transposed.

Specified by:

generate in class Generator<Object>

Parameters:

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

status - an object that the generator can use to influence the value it produces. For example, a generator for lists can use the size method to generate lists with a given number of elements.

Returns:

the generated value

configure

public void configure(Map<Class<? extends Annotation>,Annotation> configurationsByType)

Description copied from class: Generator

Tells this generator to configure itself using annotations from a theory parameter.

The annotations fed to this method will be those annotations on the theory parameter that are themselves marked with GeneratorConfiguration.

By default, the generator will configure itself by:

• For each of the given annotations:
• Find a public method on the generator named configure, that accepts a single parameter of the annotation type
• Invoke the configure method reflectively, passing the annotation as the argument

Overrides:

configure in class Generator<Object>

Parameters:

configurationsByType - a map of configuration annotations, keyed by annotation type
