## get_value_by_key()

const char * osmium::TagList::get_value_by_key | ( | const char * | key,
|  | const char * | default_value = nullptr ) const

inlinenoexcept

Get tag value for the given tag key. If the key is not set, returns the default_value.

Precondition
  key != nullptr

## has_key()

bool osmium::TagList::has_key | ( | const char * | key | ) | const

inlinenoexcept

Returns true if the tag with the given key is in the tag list.

Precondition
  key != nullptr

## has_tag()

bool osmium::TagList::has_tag | ( | const char * | key,
|  | const char * | value ) const

inlinenoexcept

Returns true if the tag with the given key and value is in the tag list.

Precondition
  key != nullptr && value != nullptr

## operator[]()

const char * osmium::TagList::operator[] | ( | const char * | key | ) | const

inlinenoexcept

Get tag value for the given tag key. If the key is not set, returns nullptr.

Precondition
  key != nullptr
