Instance Method Details

#[](*args) ⇒ Slice, Index

Indexes a BOAST::Slice

Parameters:

  • args (Array{#to_s, Range, [first, last, step], :all, nil}) —

    one entry for each SliceItem of the BOAST::Slice.

    • Range: if an index is a Range, the result will be a BOAST::Slice. The Range can be exclusive. The first and last item of the Range will be considered first and last index in the corresponding SliceItem.

    • [first, last, step]: if an index is an Array, the result will be a BOAST::Slice. The first and last item of the array will be considered first and last index in the corresponding SliceItem. If a step is given the range will be iterated by step.

    • :all, nil: The whole corresponding SliceItem will be used for the slice.

    • #to_s: If an index is none of the above it will be considered a scalar index. If all indexes are scalar an Index will be returned.

Returns:
