Internet Address Mask such as subnet masks. More...

Inherits: InetAddress
Internet addresses used specifically as masking addresses (such as " 255.255.255.0") are held in the InetMaskAddress derived object. 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.
[public]
Create the mask from a null terminated ASCII string such as "255.255.255.128".
mask | null terminated ASCII mask string. |
[public]
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.
addr | host address to be masked by subnet. |
mask | inetnet mask address object to mask by. |
