PeriodGenerator

public PeriodGenerator()

Method Details

configure

public void configure(InRange range)

Tells this generator to produce values within a specified minimum and/or maximum, inclusive, with uniform distribution.

If an endpoint of the range is not specified, the generator will use Periods with values of either Period(Year#MIN_VALUE, -12, -31) or Period(Year#MAX_VALUE, 12, 31) as appropriate.

InRange.format() is ignored. Periods are always parsed using formats based on the ISO-8601 period formats PnYnMnD and PnW.

Parameters:

range - annotation that gives the range's constraints

See Also:

• Period.parse(CharSequence)

generate

public Period 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

toBigInteger

private BigInteger toBigInteger(Period period)

fromBigInteger

private Period fromBigInteger(BigInteger period)
