Detailed Description

The network name and address objects are all derived from a common IPV6Address base class.

Specific classes, such as IPV4Host, IPV6Mask, etc, are defined from IPV6Address 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 "IPV6Host" can be kept type-safe from a "connection" accidently being made to something that was declared a "IPV6Broadcast".

Constructor & Destructor Documentation

ost::IPV6Address::IPV6Address ( IPV6Validator validator = ((void *) 0))

Create an Internet Address object with an empty (0.0.0.0) address.

Parameters:
validatoroptional validator function object, intended for derived classes.
ost::IPV6Address::IPV6Address ( struct in6_addr  addr,
IPV6Validator validator = ((void *) 0) 
)

Convert the system internet address data type (struct in_addr) into a Common C++ IPV6Address object.

Parameters:
addrstruct of system used binary internet address.
validatoroptional validator function object, intended for derived classes.
ost::IPV6Address::IPV6Address ( char *  address,
IPV6Validator validator = ((void *) 0) 
)

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++ IPV6Address object.

Parameters:
addressnull terminated C string.
validatoroptional validator function object, intended for derived classes.

Member Function Documentation

struct in6_addr ost::IPV6Address::getAddress ( void  ) [read]

Provide a low level system usable struct in_addr object from the contents of IPV6Address.

This is needed for services such as bind() and connect().

Returns:
system binary coded internet address.
struct in6_addr ost::IPV6Address::getAddress ( size_t  i) [read]

Provide a low level system usable struct in_addr object from the contents of IPV6Address.

This is needed for services such as bind() and connect().

Parameters:
ifor IPV6Addresses 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::IPV6Address::getAddressCount ( ) [inline]

Returns the number of internet addresses that an IPV6Address object contains.

This usually only happens with IPV6Host objects where multiple IP addresses are returned for a DNS lookup

Definition at line 857 of file address.h.

Provide a string representation of the value (Internet Address) held in the IPV6Address object.

Returns:
string representation of IPV6Address.

May be used to verify if a given IPV6Address returned by another function contains a "valid" address, or "0.0.0.0" which is often used to mark "invalid" IPV6Address values.

Returns:
true if address != 0.0.0.0.
bool ost::IPV6Address::operator!= ( IPV6Address a)

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==

bool ost::IPV6Address::operator== ( IPV6Address a)

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 IPV6Address object, this will return true if all of the IP addresses in the smaller are in the larger in any order.

void ost::IPV6Address::setAddress ( char *  host) [protected]

Used to specify a host name or numeric internet address.

Parameters:
hostThe string representation of the IP address or a hostname, , if NULL, it will default to INADDR_ANY
bool ost::IPV6Address::setIPAddress ( char *  host) [protected]

Sets the IP address from a string representation of the numeric address, ie "127.0.0.1".

Parameters:
hostThe string representation of the IP address
Returns:
true if successful
