ost::IPV4Address(3) | Library Functions Manual | ost::IPV4Address(3) |
NAME¶
ost::IPV4Address - The network name and address objects are all derived from a common IPV4Address base class.
SYNOPSIS¶
#include <address.h>
Inherited by ost::IPV4Broadcast, ost::IPV4Host, ost::IPV4Mask, and ost::IPV4Multicast.
Public Member Functions¶
IPV4Address (const IPV4Validator *validator=NULL)
Create an Internet Address object with an empty (0.0.0.0) address.
IPV4Address (struct in_addr addr, const IPV4Validator
*validator=NULL)
Convert the system internet address data type (struct in_addr) into a Common
C++ IPV4Address object. IPV4Address (const char *address,
const IPV4Validator *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++
IPV4Address object. IPV4Address (const IPV4Address
&rhs)
Copy constructor. virtual ~IPV4Address ()
Destructor. const char * getHostname (void) const
Provide a string representation of the value (Internet Address) held in the
IPV4Address object. bool isInetAddress (void) const
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. struct in_addr getAddress
(void) const
Provide a low level system usable struct in_addr object from the contents of
IPV4Address. struct in_addr getAddress (size_t i) const
Provide a low level system usable struct in_addr object from the contents of
IPV4Address. size_t getAddressCount () const
Returns the number of internet addresses that an IPV4Address object
contains. IPV4Address & operator= (const char *str)
IPV4Address & operator= (struct in_addr addr)
IPV4Address & operator= (const IPV4Address &rhs)
IPV4Address & operator= (unsigned long addr)
Allows assignment from the return of functions like inet_addr() or htonl()
IPV4Address & operator= (unsigned int addr)
bool operator! () const
bool 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). bool operator!= (const
IPV4Address &a) const
Compare two internet addresses to see if they are not equal (if they each
refer to unique and different physical ip addresses).
Protected Member Functions¶
bool setIPAddress (const char *host)
Sets the IP address from a string representation of the numeric address, ie
'127.0.0.1'. void setAddress (const char *host)
Used to specify a host name or numeric internet address.
Protected Attributes¶
struct in_addr * ipaddr
size_t addr_count
char * hostname
Static Protected Attributes¶
static Mutex mutex
Detailed Description¶
The network name and address objects are all derived from a common IPV4Address base class.
Specific classes, such as IPV4Host, IPV4Mask, etc, are defined from IPV4Address 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 'IPV4Host' can be kept type-safe from a 'connection' accidently being made to something that was declared a 'IPV4Broadcast'.
Author
Internet Address binary data type.
Examples
tcpthread.cpp.
Constructor & Destructor Documentation¶
ost::IPV4Address::IPV4Address (const IPV4Validator * validator = NULL)¶
Create an Internet Address object with an empty (0.0.0.0) address.
Parameters
ost::IPV4Address::IPV4Address (struct in_addr addr, const IPV4Validator * validator = NULL)¶
Convert the system internet address data type (struct in_addr) into a Common C++ IPV4Address object.
Parameters
validator optional validator function object, intended for derived classes.
ost::IPV4Address::IPV4Address (const char * address, const IPV4Validator * 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++ IPV4Address object.
Parameters
validator optional validator function object, intended for derived classes.
ost::IPV4Address::IPV4Address (const IPV4Address & rhs)¶
Copy constructor.
virtual ost::IPV4Address::~IPV4Address () [virtual]¶
Destructor.
Member Function Documentation¶
struct in_addr ost::IPV4Address::getAddress (size_t i) const¶
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
Returns
struct in_addr ost::IPV4Address::getAddress (void) const¶
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
size_t ost::IPV4Address::getAddressCount () const [inline]¶
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
const char* ost::IPV4Address::getHostname (void) const¶
Provide a string representation of the value (Internet Address) held in the IPV4Address object.
Returns
Examples
tcpthread.cpp.
bool ost::IPV4Address::isInetAddress (void) const¶
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
bool ost::IPV4Address::operator! () const [inline]¶
bool ost::IPV4Address::operator!= (const IPV4Address & 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==
IPV4Address& ost::IPV4Address::operator= (const char * str)¶
Referenced by ost::IPV4Mask::operator=(), and ost::IPV4Host::operator=().
IPV4Address& ost::IPV4Address::operator= (const IPV4Address & rhs)¶
IPV4Address& ost::IPV4Address::operator= (struct in_addr addr)¶
IPV4Address& ost::IPV4Address::operator= (unsigned int addr) [inline]¶
IPV4Address& ost::IPV4Address::operator= (unsigned long addr)¶
Allows assignment from the return of functions like inet_addr() or htonl()
bool ost::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 ost::IPV4Address::setAddress (const char * host) [protected]¶
Used to specify a host name or numeric internet address.
Parameters
bool ost::IPV4Address::setIPAddress (const char * host) [protected]¶
Sets the IP address from a string representation of the numeric address, ie '127.0.0.1'.
Parameters
Returns
