Overview

List bin operations. Create list operations used by the Client#operate command. List operations support negative indexing. If the index is negative, the resolved index starts backwards from end of list.

Index/Range examples:

  • Index 0: First item in list.

  • Index 4: Fifth item in list.

  • Index -1: Last item in list.

  • Index -3: Third to last item in list.

  • Index 1 Count 2: Second and third items in list.

  • Index -3 Count 3: Last three items in list.

  • Index -5 Count 4: Range between fifth to last item to second to last item inclusive.

If an index is out of bounds, a parameter error will be returned. If a range is partially out of bounds, the valid part of the range will be returned.
