The Header class encapsulates the headers of an HTTP request/response.
Definition: header.h:39
virtual void enumerate(const std::function< void(const std::string &, const std::set< std::string > &)> &enumerator) const
enumerate iterates over the known fields and invokes the given enumerator for each of them.
virtual bool has(const std::string &key) const
has checks if the header contains any entry for the given key.
virtual void add(const std::string &key, const std::string &value)
add adds the given value for the given key to the header.
virtual bool has(const std::string &key, const std::string &value) const
has checks if the header contains an entry for the given key with the given value.
virtual void remove(const std::string &key, const std::string &value)
remove erases the given value for the given key from the header.
virtual ~Header()=default
virtual void set(const std::string &key, const std::string &value)
set assigns the given value to the entry with key 'key' and replaces any previous value.
static std::string canonicalize_key(const std::string &key)
canonicalize_key returns the canonical form of the header key 'key'.
virtual void remove(const std::string &key)
remove erases all values for the given key from the header.
