## empty()

bool restinio::query_string_params_t::empty | ( |  | ) | const

inline noexcept

Is there any parameters?

Since
  v.0.4.8

## get_param()

optional_t< string_view_t > restinio::query_string_params_t::get_param | ( | string_view_t | key | ) | const

inline noexcept

Get the value of a parameter if it exists.

Since
  v.0.4.4

Definition at line 88 of file uri_helpers.hpp.

## has()

bool restinio::query_string_params_t::has | ( | string_view_t | key | ) | const

inline noexcept

Check parameter.

Definition at line 80 of file uri_helpers.hpp.

## operator=() [1/2]

query_string_params_t & restinio::query_string_params_t::operator= | ( | const query_string_params_t & |  | ) |

delete

## operator=() [2/2]

query_string_params_t & restinio::query_string_params_t::operator= | ( | query_string_params_t && |  | ) |

default

## operator[]()

string_view_t restinio::query_string_params_t::operator[] | ( | string_view_t | key | ) | const

inline

Get parameter.

Definition at line 73 of file uri_helpers.hpp.

## size()

auto restinio::query_string_params_t::size | ( |  | ) | const

inline noexcept

Get the size of parameters.

Definition at line 98 of file uri_helpers.hpp.

## tag()

auto restinio::query_string_params_t::tag | ( |  | ) | const

inline noexcept

Get the tag (web beacon) part.

A value of "tag" (also known as web beacon) is available only if URI looks like that:

    http://example.com/resource?value

In that case tag will contain `value`. For URI with different formats tag() will return empty optional.
