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

◆ IPV6Address() [1/3]

ost::IPV6Address::IPV6Address ( const IPV6Validator validator = NULL)

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

Parameters
validatoroptional validator function object, intended for derived classes.

◆ IPV6Address() [2/3]

ost::IPV6Address::IPV6Address ( struct in6_addr  addr,
const IPV6Validator validator = NULL 
)

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.

◆ IPV6Address() [3/3]

ost::IPV6Address::IPV6Address ( const char *  address,
const IPV6Validator 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++ IPV6Address object.

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

Member Function Documentation

◆ getAddress() [1/2]

struct in6_addr ost::IPV6Address::getAddress ( void  ) const

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.

◆ getAddress() [2/2]

struct in6_addr ost::IPV6Address::getAddress ( size_t  i) const

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.

◆ getAddressCount()

size_t ost::IPV6Address::getAddressCount ( ) const
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 899 of file address.h.

◆ getHostname()

const char* ost::IPV6Address::getHostname ( void  ) const

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

Returns
string representation of IPV6Address.

◆ isInetAddress()

bool ost::IPV6Address::isInetAddress ( void  ) const

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.

◆ operator!=()

bool ost::IPV6Address::operator!= ( const IPV6Address 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==

◆ operator==()

bool ost::IPV6Address::operator== ( const IPV6Address 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 IPV6Address object, this will return true if all of the IP addresses in the smaller are in the larger in any order.

◆ setAddress()

void ost::IPV6Address::setAddress ( const 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

◆ setIPAddress()

bool ost::IPV6Address::setIPAddress ( const 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
