Method Details

setValue

public <T> GenerationStatus setValue(GenerationStatus.Key<T> key,
 T value)

Description copied from interface: GenerationStatus

Associates the given value with the given key for the duration of the generation of a value for a property parameter, or until overwritten.

Specified by:

setValue in interface GenerationStatus

Type Parameters:

T - type of the value

Parameters:

key - a key to associate with a value

value - the associated value

Returns:

self, so that calls to this method can be chained

valueOf

public <T> Optional<T> valueOf(GenerationStatus.Key<T> key)

Description copied from interface: GenerationStatus

Retrieves the value associated with the given key.

Specified by:

valueOf in interface GenerationStatus

Type Parameters:

T - type of the value associated with the key

Parameters:

key - key to look up

Returns:

the (optional) associated value

size

public int size()

Specified by:

size in interface GenerationStatus

Returns:

an arbitrary "size" parameter; this value (probabilistically) increases for every successful generation

random

protected final SourceOfRandomness random()
