InetAddress Class Reference The network name and address objects are all derived from a common InetAddress base class. Internet Address binary data type. More... #include <socket.h> Inheritance diagram for InetAddress: List of all members. Public Methods   InetAddress ()   Create an Internet Address object with an empty (0.0.0.0) address.   InetAddress (struct in_addr addr)   Convert the system internet address data type (struct in_addr) into a Common C++ InetAddress object. More...   InetAddress (const char *address)   Convert a null terminated ASCII host address string (example: "127.0.0.1") directly into a Common C++ InetAddress object. More...   InetAddress (const InetAddress &rhs)   Copy constructor. virtual  ~InetAddress ()   Destructor. const char*  getHostname (void) const   Provide a string representation of the value (Internet Address) held in the InetAddress object. More... bool  isInetAddress (void) const   May be used to verify if a given InetAddress returned by another function contains a "valid" address, or "0.0.0.0" which is often used to mark "invalid" InetAddress values. More... struct in_addr  getAddress (void) const   Provide a low level system usable struct in_addr object from the contents of InetAddress. More... struct in_addr  getAddress (size_t i) const   Provide a low level system usable struct in_addr object from the contents of InetAddress. More... size_t  getAddressCount () const   Returns the number of internet addresses that an InetAddress object contains. More... InetAddress&  operator= (const char *str) InetAddress&  operator= (struct in_addr addr) InetAddress&  operator= (const InetAddress &rhs) InetAddress&  operator= (unsigned long addr)   Allows assignment from the return of functions like inet_addr() or htonl(). bool  operator! () const bool  operator== (const InetAddress &a) const   Compare two internet addresses to see if they are equal (if they specify the physical address of the same internet host). More... bool  operator!= (const InetAddress &a) const   Compare two internet addresses to see if they are not equal (if they each refer to unique and different physical ip addresses). More... Protected Methods bool  setIPAddress (const char *host)   Sets the IP address from a string representation of the numeric address, ie "127.0.0.1".

Protected Attributes struct in_addr*  ipaddr size_t  addr_count Static Protected Attributes MutexCounter  counter Mutex  mutex Detailed Description The network name and address objects are all derived from a common InetAddress base class. Internet Address binary data type. Specific classes, such as InetHostAddress, InetMaskAddress, etc, are defined from InetAddress 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 "InetHostAddress" can be kept type-safe from a "connection" accidently being made to something that was declared a "InetBroadcastAddress". Author(s): David Sugar <dyfet@oste.com> Constructor & Destructor Documentation InetAddress::InetAddress ( )   Create an Internet Address object with an empty (0.0.0.0) address. InetAddress::InetAddress ( struct in_addr addr )   Convert the system internet address data type (struct in_addr) into a Common C++ InetAddress object. Parameters: addr   struct of system used binary internet address. InetAddress::InetAddress ( const char * address )   Convert a null terminated ASCII host address string (example: "127.0.0.1") directly into a Common C++ InetAddress object. Parameters: address   null terminated C string. InetAddress::InetAddress ( const InetAddress & rhs )   Copy constructor. InetAddress::~InetAddress ( ) [virtual]   Destructor. Member Function Documentation struct in_addr InetAddress::getAddress ( size_t i ) const   Provide a low level system usable struct in_addr object from the contents of InetAddress. This is needed for services such as bind() and connect(). Parameters: i   for InetAddresses 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. struct in_addr InetAddress::getAddress ( void ) const   Provide a low level system usable struct in_addr object from the contents of InetAddress. This is needed for services such as bind() and connect(). Returns: system binary coded internet address. size_t InetAddress::getAddressCount ( ) const [inline]   Returns the number of internet addresses that an InetAddress object contains. This usually only happens with InetHostAddress objects where multiple IP addresses are returned for a DNS lookup const char * InetAddress::getHostname ( void ) const   Provide a string representation of the value (Internet Address) held in the InetAddress object. Returns: string representation of InetAddress. bool InetAddress::isInetAddress ( void ) const   May be used to verify if a given InetAddress returned by another function contains a "valid" address, or "0.0.0.0" which is often used to mark "invalid" InetAddress values. Returns: true if address != 0.0.0.0. bool InetAddress::operator! ( void ) const [inline] bool InetAddress::operator!= ( const InetAddress & 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== InetAddress & InetAddress::operator= ( unsigned long addr )   Allows assignment from the return of functions like inet_addr() or htonl(). Reimplemented in InetMaskAddress, and InetHostAddress. InetAddress& InetAddress::operator= ( const InetAddress & rhs ) InetAddress& InetAddress::operator= ( struct in_addr addr ) InetAddress& InetAddress::operator= ( const char * str ) bool InetAddress::operator== ( const InetAddress & 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 InetAddress object, this will return true if all of the IP addresses in the smaller are in the larger in any order. void InetAddress::setAddress ( const char * host ) [protected]   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 InetAddress::setIPAddress ( const char * host ) [protected]   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 Member Data Documentation size_t InetAddress::addr_count [protected] MutexCounter InetAddress::counter [static, protected] struct in_addr * InetAddress::ipaddr [protected] Mutex InetAddress::mutex [static, protected] The documentation for this class was generated from the following file: socket.h
