    - #### BooleanContiguousIterator

          public BooleanContiguousIterator(boolean v,
                                   Dataset a,
                                   Dataset c,
                                   Dataset o,
                                   boolean createIfNull)

      Construct a boolean iterator that stops at the position in choice dataset where its value matches the given boolean
      Parameters:
        `v` - boolean value
        `a` - primary dataset
        `c` - choice dataset
        `o` - output dataset, can be null
        `createIfNull` - if true create the output dataset if that is null

  - ### Method Detail

    - #### hasNext

          public boolean hasNext()

      Specified by:
        `hasNext` in class `IndexIterator`
      Returns:
        true if there is another iteration

    - #### getPos

          public int[] getPos()

      Specified by:
        `getPos` in class `IndexIterator`
      Returns:
        position indices (nb this is reference not a copy so avoid changing and can be null)

    - #### reset

          public void reset()

      Description copied from class: `IndexIterator`
      Reset iterator
      Specified by:
        `reset` in class `IndexIterator`
