unsigned short IPSocketAddress::anyPort (  void   )  [static]
 

Definition at line 145 of file IPSocketAddress.cc.

Referenced by thisHostAnyPort().

00146 {
00147     return 0;
00148 }

String * IPSocketAddress::bytesToName (  ByteArray *  address  )  [static]
 

Converts numeric IP address representation to string.

It does not resolv the address. Just writes out IP address in common string representation (like 127.0.0.1).

Definition at line 91 of file IPSocketAddress.cc.

References Core::Collection::printSeparatedBy().

00092 {
00093     return address->printSeparatedBy(".");
00094 }

String * IPSocketAddress::className (  void   )  const [virtual]
 

Answer receiver class name.

Because there isn't any standard way to obtain class name this method comes to place.

Every class should rewrite this method but many didn't (yet).

Reimplemented from Core::Object.

void IPSocketAddress::printOn (  Stream *  stream  )  const [virtual]
