Detailed Description
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
-
address struct 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
-
address null 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
-
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 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
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
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
-
host The 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
-
host The string representation of the IP address
- Returns
- true if successful
Field Documentation
size_t IPV4Address::addr_count
protectedinherited
char* IPV4Address::hostname
mutableprotectedinherited
struct in_addr* IPV4Address::ipaddr
protectedinherited
Check the address in addr is a valid multicast address.
In case not, throws an exception.
- Parameters
-
address a system network address
- Returns
- true if validation succeeded
