    • apply

      IntChunk<? extends T> apply(Chunk<? extends T> input)
      Description copied from interface: ToIntFunctor
      Apply this function to the input chunk, returning an output chunk. The result is owned by this Context.
      Specified by:
      apply in interface ToIntFunctor<T extends Attributes.Any>
      Parameters:
      input - the chunk to transform
      Returns:
      the result IntChunk

    • makeToIntegerCast

      static <T extends Attributes.Any> ToIntFunctor<T> makeToIntegerCast(ChunkType type, int size, int offset)
      Create an IntFunctor that casts the values in an input chunk to an int. An optional offset is applied to each value after the cast.
      Type Parameters:
      T - the chunk's attribute
      Parameters:
      type - the type of chunk, must be an integral primitive type
      size - the size of the largest chunk that can be cast by this functor
      offset - an offset to add to each casted result
      Returns:
      a ToIntFunctor that can be applied to chunks of type in order to produce an IntChunk of values
