RWSockAddrBase is an interface class that represents a socket address. All member functions are virtual. The class RWSockAddr is a proxy class that provides an interface to an RWSockAddrBase object whose exact type can be known only at run time.

virtual
operator const RWCString () const;

Conversion operator. Converts its address to an RWCString. This operator is similar to the id() function, but it can be used for implicit conversion to an RWCString. The RWCString should contain 7-bit US-ASCII data.

virtual 
~RWSockAddrBase();

Virtual destructor.

virtual const RWSockAddrBase*
myAddress() const;

Used by derived classes to implement narrowing conversions from an RWSockAddr or an RWSockAddrBase to a derived address type. It returns this, unless this address is a proxy, in which case it returns the pointer to the base class of the object being proxied.

virtual RWSockType 
addressType() const =0;

Returns the type of address.

virtual sockaddr* 
asSockaddr() const =0;

Returns a pointer to an internal representation of the address cast to a sockaddr structure, as defined by the sockets and TLI APIs (TLI is the Unix System V network communication interface). The pointer points to an internal data structure, so it becomes invalid if this object is changed in any way or goes out of scope. If the address has no representation as a sockaddr, a null pointer is returned. These operations may block if prepare() has not been called.

int 
getDomain() const;
int 
getFamily() const;

Returns the integer identifier of the address domain for the socket type, such as AF_INET for an Internet domain. getFamily() and getDomain() are synonyms.

RWCString 
getFamilyName() const;

Gets the socket family name. The RWCString should contain 7-bit US-ASCII data.

int 
getProtocol() const; 

Gets the socket protocol.

int 
getType() const; 

Gets the socket address type.

RWCString 
id(unsigned level=0) const =0;

Returns a string describing self. The verbosity of the output is controlled by level where level=0 is the most basic output, and level=9 is the most verbose. The RWCString should contain 7-bit US-ASCII data.

virtual void 
prepare() const;

Sets up all internal data so that subsequent calls to interfaces on this address do not block.

virtual size_t 
sockaddrSize() const =0;

Returns the size of an internal representation of the socket address defined by the sockets.

ostream& 
operator<<(ostream& strm, const RWSockAddrBase& x);

Outputs a representation of x on strm. The representation is generated using the member function x.id() with level=0.
