Copy constructor.
virtual ~IPV4Address ()
Destructor.
const char * getHostname (void) const

held in the IPV4Address object.
bool 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.
struct in_addr getAddress (void) const
Provide a low level system usable struct in_addr object from the
contents of IPV4Address.
struct in_addr getAddress (size_t i) const
Provide a low level system usable struct in_addr object from the
contents of IPV4Address.
size_t getAddressCount () const
Returns the number of internet addresses that an IPV4Address object
contains.
IPV4Address & operator= (const char *str)
IPV4Address & operator= (struct in_addr addr)
IPV4Address & operator= (const IPV4Address &rhs)
IPV4Address & operator= (unsigned long addr)
Allows assignment from the return of functions like inet_addr() or
htonl().
IPV4Address & operator= (unsigned int addr)
bool operator! () const
bool 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).
bool 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).
Protected Member Functions
bool setIPAddress (const char *host)
Sets the IP address from a string representation of the numeric
address, ie 127.0.0.1.
void setAddress (const char *host)
Used to specify a host name or numeric internet address.

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’.

Constructor & Destructor Documentation
ost::IPV4Address::IPV4Address (const IPV4Validator * validator = NULL)
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.
validator optional validator function object, intended for derived
classes.
ost::IPV4Address::IPV4Address (const char * address, const IPV4Validator *
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. Parameters:
address null terminated C string.
validator optional validator function object, intended for derived
classes.

Destructor.
Member Function Documentation
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.
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.
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
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.
bool ost::IPV4Address::operator! () const [inline]
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==
IPV4Address& ost::IPV4Address::operator= (unsigned int addr) [inline]
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= (const IPV4Address & rhs)
IPV4Address& ost::IPV4Address::operator= (struct in_addr addr)
IPV4Address& ost::IPV4Address::operator= (const char * str)
Referenced by ost::IPV4Host::operator=(), and
ost::IPV4Mask::operator=().
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.
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
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
