Detailed Description

Class to create a client stream connection.

This is a base class for creating active, streaming sockets that initiate connections to a server. It can be used to derive classes that implement TCP on IPv4 or IPv6.

Constructor & Destructor Documentation

◆ connector() [1/2]

sockpp::connector::connector ( const sock_address addr)
inline

Creates the connector and attempts to connect to the specified address.

Parameters
addrThe remote server address.

◆ connector() [2/2]

sockpp::connector::connector ( connector &&  conn)
inline

Move constructor.

Creates a connector by moving the other connector to this one.

Parameters
connAnother connector.

Member Function Documentation

◆ connect()

bool sockpp::connector::connect ( const sock_address addr)

Attempts to connect to the specified server.

If the socket is currently connected, this will close the current connection and open the new one.

Parameters
addrThe remote server address.
Returns
true on success, false on error

◆ is_connected()

bool sockpp::connector::is_connected ( ) const
inline

Determines if the socket connected to a remote host.

Note that this is not a reliable determination if the socket is currently connected, but rather that an initial connection was established.

Returns
true If the socket connected to a remote host, false if not.

◆ operator=()

connector& sockpp::connector::operator= ( connector &&  rhs)
inline

Move assignment.

Parameters
rhsThe other connector to move into this one.
Returns
A reference to this object.
