Constructor & Destructor Documentation

NetAddress::NetAddress (   )

Constructs an unspecified address. Definition at line 39 of file netAddress.cxx.

NetAddress::NetAddress (  const PRNetAddr &  addr  )

Constructs an address from a given PRNetAddr. Normally, this constructor should not be used by user code; instead, create a default NetAddress and use one of the set_*() functions to set up an address. Definition at line 58 of file netAddress.cxx. References _addr.

Member Function Documentation

void NetAddress::clear (   )

Resets the NetAddress to its initial state. Definition at line 209 of file netAddress.cxx. References _addr, and pprerror(). Referenced by NetDatagram::NetDatagram().

PRNetAddr * NetAddress::get_addr (   )  const

Returns the PRNetAddr for this address. Definition at line 312 of file netAddress.cxx.

PN_uint32 NetAddress::get_ip (   )  const

Returns the IP address to which this address refers, as a 32-bit integer, in host byte order. Definition at line 277 of file netAddress.cxx.

PN_uint8 NetAddress::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. Definition at line 296 of file netAddress.cxx.

string NetAddress::get_ip_string (   )  const

Returns the IP address to which this address refers, formatted as a string. Definition at line 252 of file netAddress.cxx. References _addr. Referenced by ConnectionListener::receive_datagram().

int NetAddress::get_port (   )  const

Returns the port number to which this address refers. Definition at line 222 of file netAddress.cxx.

void NetAddress::output (  ostream &  out  )  const

Definition at line 324 of file netAddress.cxx.

bool NetAddress::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). Definition at line 77 of file netAddress.cxx.

bool NetAddress::set_host (  const string &  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. Definition at line 113 of file netAddress.cxx. Referenced by ConnectionManager::open_TCP_client_connection().

bool NetAddress::set_localhost (  int  port  )

Sets the address up to refer to a particular port, on this host. Definition at line 94 of file netAddress.cxx. References size_t.

void NetAddress::set_port (  int  port  )

Resets the port number without otherwise changing the address. Definition at line 237 of file netAddress.cxx. References _addr, nassertr, and PN_uint8.
