Detailed Description

Support for IP version 4 host address.

This class provides by-name and by-address name service lookup, and caches the names and addresses in static maps.

Constructor & Destructor Documentation

Inet4Address::Inet4Address ( )

Default constructor.

Creates address: 0.0.0.0, aka: INADDR_ANY.

Inet4Address::Inet4Address ( const struct in_addr * a )

Construct an address from a pointer to the C in_addr structure.

Inet4Address::Inet4Address ( unsigned int addr )

Construct an address.

References _inaddr.

Member Function Documentation

int Inet4Address::bitsMatch	(	const Inet4Address &	x	)	const
throw	(
	)

How many leading bits match in the two addresses?

list< Inet4Address > Inet4Address::getAllByName	(	const std::string &	hostname	)
throw	(	UnknownHostException
	)

static

Static method returning a list of addresses for a name.

This is the name-to-address lookup method.

Parameters

hostname,: either a local hostname, like "linus", or a fully qualified name, "linus.atd.ucar.edu", or an address in dot notation: "128.117.80.208".

Inet4Address Inet4Address::getByName	(	const std::string &	hostname	)
throw	(	UnknownHostException
	)

static

Return an address of a name, the first one found by getAllByName.

string Inet4Address::getHostName	(	const Inet4Address &	addr	)
throw	(
	)

static

Do reverse lookup of a name, given an address.

This is the address-to-name lookup method. If a host name is not found for the address, returns a string in dot notation: "x.x.x.x" using getHostAddress().

References ELOG, err, nidas::util::Exception::errnoToString(), and WLOG.

Referenced by nidas::util::Inet4SocketAddress::toString().

string Inet4Address::getHostName	(	)	const
throw	(
	)

Return a hostname for this address.

Calls static getHostName() method.

struct in_addr nidas::util::Inet4Address::getInAddr ( ) const

inline

Get the structure containing the 4 byte internet version 4 address.

To get the actual 4 byte integer value:

uint32_t addr = getInAddr().s_addr;

References _inaddr.

struct in_addr* nidas::util::Inet4Address::getInAddrPtr ( ) const

inline

Return const pointer to struct in_addr.

bool nidas::util::Inet4Address::isMultiCastAddress ( ) const

inline

Is this address a multicast address? Multicast addresses are in the range 224.0.0.1 to 239.255.255.255, their first four bits are 1110=0xe.
