Detailed Description

Internet addresses used specifically as masking addresses (such as " 255.255.255.0") are held in the InetMaskAddress derived object. Internet Address Mask such as subnet masks.

The seperate class is used so that C++ type casting can automatically determine when an InetAddress object is really a mask address object rather than simply using the base class. This also allows manipulative operators for address masking to operate only when presented with a Masked address as well as providing cleaner and safer source.

Member Function Documentation

InetAddress& InetMaskAddress::operator= (  unsigned long   addr )  [inline]

Allows assignment from the return of functions like inet_addr() or htonl(). Reimplemented from InetAddress.

Friends And Related Function Documentation

InetHostAddress operator & (  const InetHostAddress &   addr, const InetMaskAddress &   mask )  [friend]

Masks are usually used to coerce host addresses into a specific router or class domain. This can be done by taking the Inet Host Address object and "and"ing it with an address mask. This operation can be directly expressed in C++ through the & operator. Returns: a internet host address that has been masked. Parameters: addr   host address to be masked by subnet. mask   inetnet mask address object to mask by.
