- - ### Constructor Detail

    - #### TemporalValueRange

          public TemporalValueRange(Temporal_ from,
                                    Temporal_ to,
                                    long incrementUnitAmount,
                                    TemporalUnit incrementUnitType)

      Parameters:
        `from` - never null, inclusive minimum
        `to` - never null, exclusive maximum, `>= from`
        `incrementUnitAmount` - `> 0`
        `incrementUnitType` - never null, must be `supported` by `from` and `to`

  - ### 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`

    - #### get

          public Temporal_ 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)

    - #### contains

          public boolean contains(Temporal_ value)

      Parameters:
        `value` - sometimes null
      Returns:
        true if the ValueRange contains that value

    - #### createOriginalIterator

          public Iterator<Temporal_> createOriginalIterator()

      Description copied from interface: `CountableValueRange`
      Select the elements in original (natural) order.
      Returns:
        never null

    - #### createRandomIterator

          public Iterator<Temporal_> 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 `EnvironmentMode.REPRODUCIBLE` works correctly. `RandomUtils` can be useful too.
      Returns:
        never null

    - #### toString

          public String toString()

      Overrides:
        `toString` in class `Object`
