ost::IPV4Address::IPV4Address(constIPV4Validator*validator=NULL)
       Create an Internet Address object with an empty (0.0.0.0) address.

       Parametersvalidator optional validator function object, intended for derived classes.

   ost::IPV4Address::IPV4Address(structin_addraddr,constIPV4Validator*validator=NULL)
       Convert the system internet address data type (struct in_addr) into a Common C++ IPV4Address object.

       Parametersaddr struct of system used binary internet address.
           validator optional validator function object, intended for derived classes.

   ost::IPV4Address::IPV4Address(constchar*address,constIPV4Validator*validator=NULL)
       Convert a null terminated ASCII host address string (example: '127.0.0.1') or host address name (example:
       'www.voxilla.org') directly into a Common C++ IPV4Address object.

       Parametersaddress null terminated C string.
           validator optional validator function object, intended for derived classes.

   ost::IPV4Address::IPV4Address(constIPV4Address&rhs)
       Copy constructor.

   virtualost::IPV4Address::~IPV4Address()[virtual]
       Destructor.

       The network name and address objects are all derived from a common IPV4Address base class.

       Specific classes, such as IPV4Host, IPV4Mask, etc, are defined from IPV4Address entirely so that the
       manner a network address is being used can easily be documented and understood from the code and to avoid
       common errors and accidental misuse of the wrong address object. For example, a 'connection' to something
       that is declared as a 'IPV4Host' can be kept type-safe from a 'connection' accidently being made to
       something that was declared a 'IPV4Broadcast'.

structin_addrost::IPV4Address::getAddress(size_ti)const
       Provide a low level system usable struct in_addr object from the contents of IPV4Address. This is needed
       for services such as bind() and connect().

       Parametersi for IPV4Addresses with multiple addresses, returns the address at this index. User should call
           getAddressCount() to determine the number of address the object contains.

       Returns
           system binary coded internet address. If parameter i is out of range, the first address is returned.

   structin_addrost::IPV4Address::getAddress(void)const
       Provide a low level system usable struct in_addr object from the contents of IPV4Address. This is needed
       for services such as bind() and connect().

       Returns
           system binary coded internet address.

   size_tost::IPV4Address::getAddressCount()const[inline]
       Returns the number of internet addresses that an IPV4Address object contains. This usually only happens
       with IPV4Host objects where multiple IP addresses are returned for a DNS lookup

   constchar*ost::IPV4Address::getHostname(void)const
       Provide a string representation of the value (Internet Address) held in the IPV4Address object.

       Returns
           string representation of IPV4Address.

   boolost::IPV4Address::isInetAddress(void)const
       May be used to verify if a given IPV4Address returned by another function contains a 'valid' address, or
       '0.0.0.0' which is often used to mark 'invalid' IPV4Address values.

       Returns
           true if address != 0.0.0.0.

   boolost::IPV4Address::operator!()const[inline]boolost::IPV4Address::operator!=(constIPV4Address&a)const
       Compare two internet addresses to see if they are not equal (if they each refer to unique and different
       physical ip addresses). This is implimented in terms of operator==

   IPV4Address&ost::IPV4Address::operator=(constchar*str)
       Referenced by ost::IPV4Mask::operator=(), and ost::IPV4Host::operator=().

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

   boolost::IPV4Address::operator==(constIPV4Address&a)const
       Compare two internet addresses to see if they are equal (if they specify the physical address of the same
       internet host). If there is more than one IP address in either IPV4Address object, this will return true
       if all of the IP addresses in the smaller are in the larger in any order.

   voidost::IPV4Address::setAddress(constchar*host)[protected]
       Used to specify a host name or numeric internet address.

       Parametershost The string representation of the IP address or a hostname, , if NULL, it will default to
           INADDR_ANY

   boolost::IPV4Address::setIPAddress(constchar*host)[protected]
       Sets the IP address from a string representation of the numeric address, ie '127.0.0.1'.

       Parametershost The string representation of the IP address

       Returns
           true if successful
