All Implemented Interfaces:
CountableValueRange<Boolean>, ValueRange<Boolean>
public final class BooleanValueRange extends AbstractCountableValueRange<Boolean>

  • Constructor Details

    • BooleanValueRange

      public BooleanValueRange()

  • Method Details

    • getSize

      public long getSize()
      Description copied from interface: CountableValueRange
      Used by uniform random selection in a composite CountableValueRange, or one which includes nulls.
      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 CountableValueRange, or one which includes nulls.
      Parameters:
      index - always < CountableValueRange.getSize()
      Returns:
      sometimes null (if PlanningVariable.allowsUnassigned() is true)

    • createOriginalIterator

      public @NonNull Iterator<Boolean> createOriginalIterator()
      Description copied from interface: CountableValueRange
      Select the elements in original (natural) order.

    • createRandomIterator

      public @NonNull Iterator<Boolean> createRandomIterator(@NonNull 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 - the Random to use when any random number is needed, so runs are reproducible.

    • toString

      public String toString()
      Overrides:
      toString in class Object
