inlineprivatenoexcept

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
