## Detailed Description

Compares a tags key (and value) against the specified StringMatchers.

## Constructor & Destructor Documentation

## ◆ TagMatcher() [1/3]

osmium::TagMatcher::TagMatcher | ( |  | ) |
| inline

Create a default TagMatcher that matches no tags.

## ◆ TagMatcher() [2/3]

template<typename TKey , typename X = std::enable_if_t< std::is_convertible<TKey, osmium::StringMatcher>::value, void>>

osmium::TagMatcher::TagMatcher | ( | TKey && | key_matcher | ) |
| inline explicit

Create a TagMatcher matching the key against the specified StringMatcher.

Parameters

  key_matcher | StringMatcher for matching the key.

## ◆ TagMatcher() [3/3]

template<typename TKey , typename TValue , typename std::enable_if_t< std::is_convertible< TKey, osmium::StringMatcher >::value, int > = 0, typename std::enable_if_t< std::is_convertible< TValue, osmium::StringMatcher >::value, int > = 0>

osmium::TagMatcher::TagMatcher | ( | TKey && | key_matcher,
|  | TValue && | value_matcher,
|  | bool | invert = false )
| inline

Create a TagMatcher matching the key and value against the specified StringMatchers.

Parameters

  key_matcher | StringMatcher for matching the key.
  value_matcher | StringMatcher for matching the value.
  invert | If set to true, invert the result of the value_matcher.

## Member Function Documentation

## ◆ has_value_matcher()

bool osmium::TagMatcher::has_value_matcher | ( |  | ) | const
| inline noexcept

## ◆ operator()() [1/3]

bool osmium::TagMatcher::operator() | ( | const char * | key,
|  | const char * | value ) const
| inline noexcept

Match against the specified key and value.

Returns
  true if the tag matches.

## ◆ operator()() [2/3]

bool osmium::TagMatcher::operator() | ( | const osmium::Tag & | tag | ) | const
| inline noexcept

Match against the specified tag.

Returns
  true if the tag matches.

## ◆ operator()() [3/3]

bool osmium::TagMatcher::operator() | ( | const osmium::TagList & | tags | ) | const
| inline noexcept

Match against the specified tags.

Returns
  true if any of the tags in the TagList matches.
