Instance Method Details

#checksum ⇒ String

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Calculates the checksum for this array. Any change to this array will result in a different checksum.

Returns:

  • (String) —

    The checksum for this array

def checksum
  Marshal.dump(self).checksum
end

#freeze_recursively ⇒ void

This method returns an undefined value.

Freezes the contents of the array, as well as all array elements. The array elements will be frozen using #freeze_recursively if they respond to that message, or #freeze if they do not.

  • Hash#freeze_recursively

Since:

  • 3.2.0

      value.freeze
    end
  end
end

#stringify_keys ⇒ Array

Returns a new array where all items’ keys are recursively converted to strings by calling #stringify_keys or HashExtensions#stringify_keys.

Returns:

  end
end

#symbolize_keys ⇒ Array

Returns a new array where all items’ keys are recursively converted to symbols by calling #symbolize_keys or HashExtensions#symbolize_keys.

Returns:
