BooleanValueRange

public BooleanValueRange()

Method Detail

getSize

public long getSize()

Description copied from interface: CountableValueRange

Used by uniform random selection in a composite or nullable CountableValueRange.

Returns:

the exact number of elements generated by this CountableValueRange, always >= 0

contains

public boolean contains(Boolean value)

Parameters:

value - sometimes null

Returns:

true if the ValueRange contains that value

get

public Boolean get(long index)

Description copied from interface: CountableValueRange

Used by uniform random selection in a composite or nullable CountableValueRange.

Parameters:

index - always < CountableValueRange.getSize()

Returns:

sometimes null (if PlanningVariable.nullable() is true)

createOriginalIterator

public Iterator<Boolean> createOriginalIterator()

Description copied from interface: CountableValueRange

Select the elements in original (natural) order.

Returns:

never null

createRandomIterator

public Iterator<Boolean> createRandomIterator(Random workingRandom)

Description copied from interface: ValueRange

Select in random order, but without shuffling the elements. Each element might be selected multiple times. Scales well because it does not require caching.

Parameters:

workingRandom - never null, the Random to use when any random number is needed, so runs are reproducible.

Returns:

never null

toString

public String toString()

Overrides:

toString in class Object
