Detailed Description

A specialization of IPV4Address that provides address validation for multicast addresses.

Whenever its value changes the new value is checked to be in the range from 224.0.0.1 through 239.255.255.255. If it is not, an exception is thrown.

A multicast network address.

Constructor & Destructor Documentation

IPV4Multicast::IPV4Multicast ( )

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

IPV4Multicast::IPV4Multicast ( const struct in_addr  address)

Convert the system internet address data type (struct in_addr) into a Common C++ IPV4Multicast object.

Parameters
addressstruct of system used binary internet address.
IPV4Multicast::IPV4Multicast ( const char *  address)

Convert a null terminated ASCII multicast address string (example: "224.0.0.1") or multicast name string (example: "sap.mcast.net") directly into a Common C++ IPV4Multicast object.

Works like IPV4Address(const char*).

Parameters
addressnull terminated C string.

Member Function Documentation

struct in_addr IPV4Address::getAddress ( void  ) const
inherited

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 IPV4Address::getAddress ( size_t  i) const
inherited

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
ifor 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 IPV4Address::getAddressCount ( ) const
inlineinherited

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

Definition at line 472 of file address.h.

const char* IPV4Address::getHostname ( void  ) const
inherited

Provide a string representation of the value (Internet Address) held in the IPV4Address object.

Returns
string representation of IPV4Address.
bool IPV4Address::isInetAddress ( void  ) const
inherited

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 IPV4Address::operator! ( ) const
inlineinherited

Definition at line 487 of file address.h.

bool IPV4Address::operator!= ( const IPV4Address a) const
inherited

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 IPV4Address::operator== ( const IPV4Address a) const
inherited

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 IPV4Address::setAddress ( const char *  host)
protectedinherited

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 IPV4Address::setIPAddress ( const char *  host)
protectedinherited

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

Returns
true if validation succeeded
