Converts the query component to a Hash value.

@option [Symbol] notation

  May be one of <code>:flat</code>, <code>:dot</code>, or
  <code>:subscript</code>. The <code>:dot</code> notation is not
  supported for assignment. Default value is <code>:subscript</code>.

@return [Hash, Array] The query string parsed as a Hash or Array object.

@example

  WebMock::Util::QueryMapper.query_to_values("?one=1&two=2&three=3")
  #=> {"one" => "1", "two" => "2", "three" => "3"}
  WebMock::Util::QueryMapper("?one[two][three]=four").query_values
  #=> {"one" => {"two" => {"three" => "four"}}}
  WebMock::Util::QueryMapper.query_to_values("?one.two.three=four",
    :notation => :dot
  )
  #=> {"one" => {"two" => {"three" => "four"}}}
  WebMock::Util::QueryMapper.query_to_values("?one[two][three]=four",
    :notation => :flat
  )
  #=> {"one[two][three]" => "four"}
  WebMock::Util::QueryMapper.query_to_values("?one.two.three=four",
    :notation => :flat
  )
  #=> {"one.two.three" => "four"}
  WebMock::Util::QueryMapper(
    "?one[two][three][]=four&one[two][three][]=five"
  )
  #=> {"one" => {"two" => {"three" => ["four", "five"]}}}
  WebMock::Util::QueryMapper.query_to_values(
    "?one=two&one=three").query_values(:notation => :flat_array)
  #=> [['one', 'two'], ['one', 'three']]

new_query_values have form [[‘key1’, ‘value1’], [‘key2’, ‘value2’]]

Sets the query component for this URI from a Hash object. This method produces a query string using the :subscript notation. An empty Hash will result in a nil query.

@param [Hash, to_hash, Array] new_query_values The new query values.
