Detailed Description
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'.

- Create an Internet Address object with an empty (0.0.0.0) address.
- Parameters:
validator optional validator function object, intended for derived classes.
- ost::IPV4Address::IPV4Address (struct in_addr addr, const IPV4Validator *
- validator = NULL)
Convert the system internet address data type (struct in_addr) into a
Common C++ IPV4Address object. - Parameters:
addr struct of system used binary internet address.

'127.0.0.1') or host address name (example: 'www.voxilla.org') directly into a Common C++ IPV4Address object. - Parameters:
address null terminated C string.

Member Function Documentation
- bool ost::IPV4Address::setIPAddress (const char * host) [protected]
- Sets the IP address from a string representation of the numeric
address, ie '127.0.0.1'. - Parameters:
host The string representation of the IP address
- Returns:
true if successful
- void ost::IPV4Address::setAddress (const char * host) [protected]
- Used to specify a host name or numeric internet address.
- Parameters:
host The string representation of the IP address or a hostname, , if NULL, it will default to INADDR_ANY
- const char* ost::IPV4Address::getHostname (void) const
- Provide a string representation of the value (Internet Address) held in the IPV4Address object.
- Returns:
string representation of IPV4Address.
- Examples:
tcpthread.cpp.
- bool ost::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.
- struct in_addr ost::IPV4Address::getAddress (void) const [read]
- 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.
- struct in_addr ost::IPV4Address::getAddress (size_t i) const [read]
- 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().
- Parameters:
i 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. - size_t ost::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
- IPV4Address& ost::IPV4Address::operator= (const char * str)
- Referenced by ost::IPV4Host::operator=(), and
ost::IPV4Mask::operator=(). - IPV4Address& ost::IPV4Address::operator= (struct in_addr addr) IPV4Address& ost::IPV4Address::operator= (const IPV4Address & rhs) IPV4Address& ost::IPV4Address::operator= (unsigned long addr)
- Allows assignment from the return of functions like inet_addr() or
htonl(). - Reimplemented in ost::IPV4Mask, and ost::IPV4Host.
- IPV4Address& ost::IPV4Address::operator= (unsigned int addr) [inline] bool ost::IPV4Address::operator! () const [inline] bool ost::IPV4Address::operator== (const IPV4Address & 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. - bool ost::IPV4Address::operator!= (const IPV4Address & 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==
