Constructor Details

#initialize(str_or_parts = nil) ⇒ Path

Returns a new instance of Path.

Parameters:

  • str_or_parts (String, Array, nil) (defaults to: nil) —

    ([]) If set to a String, splits the string by ‘/’ into an array. If set to an Array, sets parts to a duplicate of the array. If set to nil or not specified, defaults to a new array.

Raises:

  • (TypeError) —

    if something other than a String, Array, or nil is specified for str_or_parts.
