Instance Method Details

#heach_range(rng, &ruby_block) ⇒ Object

Iterator on each of the elements in range +rng+. NOTE:

  • Stop iteration when the end of the range is reached or when there are no elements left
  • This is not a method from Ruby but one specific for hardware where creating a array is very expensive.
