Public Methods
	InetAddress (const::std::string &h_name, U2Byte prt)
	Create an InetAddress from a hostname/dotted-quad and port #.
	InetAddress (U2Byte port)
	Create an InetAddress pointing an INADDR_ANY and a port #.
	InetAddress (const InetAddress &b)
	Create a copy of another InetAddress.
	InetAddress (const::sockaddr_in &iadr)
	Create an InetAddress from the associated sockaddr_in structure.
virtual	~InetAddress ()
	No pointers or anything, so not much to destroy.
virtual int	AreYouA (const ClassIdent &cid) const
virtual::sockaddr *	SockAddr ()
	Get the sockaddr struct this object is wrapping.
InetAddress *	Copy () const
	Clone this address, no matter it's actual type.
virtual int	AddressSize () const
	How long is this address in memory?
virtual::std::string	AsString ()
	Fetch a string representation of the SocketAddress.
::std::string	GetHostname () const
	Get the host name associated with this address, possibly the result of a reverse DNS lookup.
::std::string	GetHostname (bool forcelookup)
	Get the host name associated with this address, possibly the result of a reverse DNS lookup.
U2Byte	GetPort () const
	Get the port number.
const InetAddress &	operator= (const InetAddress &b)
	Only necessary because of the DNS lookups.
const InetAddress &	operator= (const::sockaddr_in &iadr)
	Copy an InetAddress from a sockaddr_in structure.
Static Public Attributes
const NET_ClassIdent	identifier
	Globally unique identifier for this class.
Protected Methods
virtual const lcore::ClassIdent *	i_GetIdent () const
	Returns the class identifier for the class the object actually is.
virtual SocketAddress *	MakeCopy () const
	Clone this address, no matter it's actual type.
void	InvalidateAddress ()
	Mark this address as invalid.
Static Protected Methods
bool	ParseNumeric (const char *numeric_addr, U4Byte &num)
	Parse out a dotted-quad.
bool	NameToIaddr (const char *name_addr, U4Byte &num)
	Lookup an IPV4 address from a hostname - returns false on failure.
::std::string	IaddrToName (const::sockaddr_in &inaddr)
	Lookup a hostname from an IPV4 address.

Detailed Description

An IPV4 TCP or UDP address.

This class represents an IPV4 TCP or UDP address. It doesn't represent a straight IPV4 address because it has a port number.

This class has the nasty habit of doing blocking DNS lookups at random times. This may cause a several second pause while they're going on.

Constructor & Destructor Documentation

strmod::ehnet::InetAddress::InetAddress (  const::std::string &    h_name, U2Byte    prt )

Create an InetAddress from a hostname/dotted-quad and port #. Parameters: h_name  A host name (i.e. omnifarious.omnifarious.org) , or dotted-quad (i.e. 208.42.65.33). prt  A TCP or UDP port number. Definition at line 132 of file InetAddress.cxx.

strmod::ehnet::InetAddress::InetAddress (  U2Byte    port )

Create an InetAddress pointing an INADDR_ANY and a port #. Parameters: port  A TCP or UDP port number Definition at line 166 of file InetAddress.cxx.

strmod::ehnet::InetAddress::InetAddress (  const::sockaddr_in &    iadr )

Create an InetAddress from the associated sockaddr_in structure. Useful for addresses you get back from accept(2) or getpeername(2)

---

Member Function Documentation

InetAddress* strmod::ehnet::InetAddress::Copy (    )  const [inline]

Clone this address, no matter it's actual type. This is a non-virtual for compilers that don't support contravariance in the return types of virtual functions. Reimplemented from strmod::ehnet::SocketAddress. Definition at line 120 of file InetAddress.h.

virtual const lcore::ClassIdent* strmod::ehnet::InetAddress::i_GetIdent (    )  const [inline, protected, virtual]

Returns the class identifier for the class the object actually is. Should always be overridden in any class that has a static identifier member. Reimplemented from strmod::ehnet::SocketAddress. Definition at line 140 of file InetAddress.h.

const InetAddress& strmod::ehnet::InetAddress::operator= (  const::sockaddr_in &    iadr )

Copy an InetAddress from a sockaddr_in structure. Useful for addresses you get back from accept(2) or getpeername(2).

Member Data Documentation

const NET_ClassIdent strmod::ehnet::InetAddress::identifier [static]

Globally unique identifier for this class. Every class that might need to be identified should have a public static const identifier object in it. Reimplemented from strmod::ehnet::SocketAddress.
