Constructor & Destructor Documentation

◆ TCPEndpoint() [1/4]

isc::asiolink::TCPEndpoint::TCPEndpoint ( )

inline

Default Constructor.

Creates an internal endpoint. This is expected to be set by some external call.

Definition at line 34 of file tcp_endpoint.h.

◆ TCPEndpoint() [2/4]

isc::asiolink::TCPEndpoint::TCPEndpoint	(	const IOAddress &	address,
		const unsigned short	port )

inline

Constructor from a pair of address and port.

Parameters

address	The IP address of the endpoint.
port	The TCP port number of the endpoint.

Definition at line 43 of file tcp_endpoint.h.

◆ TCPEndpoint() [3/4]

isc::asiolink::TCPEndpoint::TCPEndpoint ( boost::asio::ip::tcp::endpoint & asio_endpoint )

inline

Constructor from an ASIO TCP endpoint.

This constructor is designed to be an efficient wrapper for the corresponding ASIO class, tcp::endpoint.

Parameters

asio_endpoint The ASIO representation of the TCP endpoint.

Definition at line 56 of file tcp_endpoint.h.

◆ TCPEndpoint() [4/4]

isc::asiolink::TCPEndpoint::TCPEndpoint ( const boost::asio::ip::tcp::endpoint & asio_endpoint )

inline

Constructor from an ASIO TCP endpoint.

This constructor is designed to be an efficient wrapper for the corresponding ASIO class, tcp::endpoint.

Parameters

asio_endpoint The ASIO representation of the TCP endpoint.

Definition at line 66 of file tcp_endpoint.h.

◆ ~TCPEndpoint()

virtual isc::asiolink::TCPEndpoint::~TCPEndpoint ( )

inlinevirtual

The destructor.

Definition at line 72 of file tcp_endpoint.h.

Member Function Documentation

◆ getAddress()

virtual IOAddress isc::asiolink::TCPEndpoint::getAddress ( ) const

inlinevirtual

Returns the address of the endpoint.

This method returns an IOAddress object corresponding to this endpoint.

Note that the return value is a real object, not a reference or a pointer.

This is aligned with the interface of the ASIO counterpart: the address() method of ip::xxx::endpoint classes returns an ip::address object.

This also means handling the address of an endpoint using this method can be expensive. If the address information is necessary in a performance sensitive context and there's a more efficient interface for that purpose, it's probably better to avoid using this method.

This method never throws an exception.

Returns: A copy of IOAddress object corresponding to the endpoint.

Implements isc::asiolink::IOEndpoint.

Definition at line 75 of file tcp_endpoint.h.

◆ getASIOEndpoint() [1/2]

boost::asio::ip::tcp::endpoint & isc::asiolink::TCPEndpoint::getASIOEndpoint ( )

inline

Definition at line 100 of file tcp_endpoint.h.

◆ getASIOEndpoint() [2/2]

const boost::asio::ip::tcp::endpoint & isc::asiolink::TCPEndpoint::getASIOEndpoint ( ) const

inline

Definition at line 97 of file tcp_endpoint.h.

Referenced by isc::asiolink::TCPSocket< C >::asyncReceive(), and isc::asiolink::TLSSocket< C >::asyncReceive().

◆ getFamily()

virtual short isc::asiolink::TCPEndpoint::getFamily ( ) const

inlinevirtual

Returns the address family of the endpoint.

Implements isc::asiolink::IOEndpoint.

Definition at line 91 of file tcp_endpoint.h.

◆ getPort()

virtual uint16_t isc::asiolink::TCPEndpoint::getPort ( ) const

inlinevirtual

Returns the port of the endpoint.

Implements isc::asiolink::IOEndpoint.

Definition at line 83 of file tcp_endpoint.h.

◆ getProtocol()

virtual short isc::asiolink::TCPEndpoint::getProtocol ( ) const

inlinevirtual

Returns the protocol number of the endpoint (TCP, UDP...)

Implements isc::asiolink::IOEndpoint.

Definition at line 87 of file tcp_endpoint.h.

◆ getSockAddr()

virtual const struct sockaddr & isc::asiolink::TCPEndpoint::getSockAddr ( ) const

inlinevirtual

Returns the address of the endpoint in the form of sockaddr structure.

The actual instance referenced by the returned value of this method is of per address family structure: For IPv4 (AF_INET), it's sockaddr_in; for IPv6 (AF_INET6), it's sockaddr_in6. The corresponding port and address members of the underlying structure will be set in the network byte order.

This method is "redundant" in that all information to construct the sockaddr is available via the other "get" methods. It is still defined for performance sensitive applications that need to get the address information, such as for address based access control at a high throughput. Internally it is implemented with minimum overhead such as data copy (this is another reason why this method returns a reference).

As a tradeoff, this method is more fragile; it assumes that the underlying ASIO implementation stores the address information in the form of sockaddr and it can be accessed in an efficient way. This is the case as of this writing, but if the underlying implementation changes this method may become much slower or its interface may have to be changed, too.

It is therefore discouraged for normal applications to use this method. Unless the application is very performance sensitive, it should use the other "get" method to retrieve specific information of the endpoint.

The returned reference is only valid while the corresponding IOEndpoint is valid. Once it's destructed the reference will become invalid.

Exceptions

None

Returns: Reference to a sockaddr structure corresponding to the endpoint.
