Represents a network address to which UDP packets may be sent or to which a TCP socket may be bound.
NetAddress(NetAddress const&) = default¶
Constructs an unspecified address.
Constructs an address from a given
Socket_Address. Normally, this constructor should not be used by user code; instead, create a default
NetAddressand use one of the set_*() functions to set up an address.
std::size_t get_hash(void) const¶
uint32_t get_ip(void) const¶
Returns the IP address to which this address refers, as a 32-bit integer, in host byte order.
Deprecated: Does not work with IPv6 addresses.
uint8_t get_ip_component(int n) const¶
Returns the nth 8-bit component of the IP address. An IP address has four components; component 0 is the first (leftmost), and component 3 is the last (rightmost) in the dotted number convention.
std::string get_ip_string(void) const¶
Returns the IP address to which this address refers, formatted as a string.
int get_port(void) const¶
Returns the port number to which this address refers.
bool is_any(void) const¶
Returns true if the IP address has only zeroes.
void output(std::ostream &out) const¶
bool set_any(int port)¶
Sets the address up to refer to a particular port, but not to any particular IP. Returns true if successful, false otherwise (currently, this only returns true).
bool set_broadcast(int port)¶
Sets the address to the broadcast address.
bool set_host(std::string const &hostname, int port)¶
Sets the address up to refer to a particular port on a particular host. Returns true if the hostname is known, false otherwise.
bool set_localhost(int port)¶
Sets the address up to refer to a particular port, on this host.
void set_port(int port)¶
Resets the port number without otherwise changing the address.
