## Class SliceNDIterator

- java.lang.Object
- - org.eclipse.january.dataset.IndexIterator
  - - org.eclipse.january.dataset.SliceNDIterator

-     public class SliceNDIterator
      extends IndexIterator

  Class to provide slice iteration through a dataset

  It allows a number of axes to be omitted and iterates over the axes left over.

    - #### SliceNDIterator

          public SliceNDIterator(SliceND slice,
                         int... axes)

      Constructor for an iterator that misses out several axes
      Parameters:
        `slice` -
        `axes` - missing axes

  - ### 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)

    - #### getOmittedSlice

          public SliceND getOmittedSlice()

      Get omitted part of source slice which never changes
      Returns:
        slice (can be null)

    - #### getOutputSlice

          public SliceND getOutputSlice()

      Get output or destination slice
      Returns:
        slice

    - #### getCurrentSlice

          public SliceND getCurrentSlice()

      Get current slice
      Returns:
        slice

    - #### getUsedPos

          public int[] getUsedPos()

      Shortened position where axes are omitted
      Returns:
        used position

    - #### getUsedSlice

          public SliceND getUsedSlice()

      Shortened slice where axes are omitted
      Returns:
        used slice

    - #### getOmit

          public boolean[] getOmit()

      Returns:
        omit array - array where true means miss out

    - #### reset

          public void reset()

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

    - #### getShape

          public int[] getShape()

      Overrides:
        `getShape` in class `IndexIterator`
      Returns:
        shape of iterator (can be null, if not known or applicable)
