NetAddress
(void)¶
-
NetAddress
(Socket_Address const &addr)¶
-
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 defaultNetAddress
and use one of the set_*() functions to set up an address.
-
void
clear
(void)¶ Resets the
NetAddress
to its initial state.
-
Socket_Address const &
get_addr
(void) const¶ Returns the
Socket_Address
for this 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.
