Internet addresses used specifically as masking addresses (such as "
255.255.255.0") are held in the IPV4Mask derived object.
The seperate class is used so that C++ type casting can automatically determine when an IPV4Address object is really a mask address object rather than simply using the base class. This also allows manipulative operators for address masking to operate only when presented with a Masked address as well as providing cleaner and safer source.

| IPV4Mask::IPV4Mask |
( |
const char * |
mask | ) |
|
Create the mask from a null terminated ASCII string such as "255.255.255.128".
- Parameters
-
| mask | null terminated ASCII mask string. |
| 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==
Allows assignment from the return of functions like inet_addr() or htonl()
Definition at line 550 of file address.h.
| 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
-
| 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
Masks are usually used to coerce host addresses into a specific router or class domain.
This can be done by taking the Inet Host Address object and "and"ing it with an address mask. This operation can be directly expressed in C++ through the & operator.
- Returns
- a internet host address that has been masked.
- Parameters
-
| addr | host address to be masked by subnet. |
| mask | inetnet mask address object to mask by. |
