◆ RemoteTcpClient() [2/2]

RemoteTcpClient::RemoteTcpClient	(	const std::string &	hostname,
		int	port,
		double	timeout_,
		double	timeout_connect,
		bool	writable,
		int	flags
	)

inline

Constructor.

Attempts to open a TCP/IP connection to xapian-tcpsrv running on port port of host hostname.

Parameters

timeout_connect	Timeout for trying to connect (in seconds).
timeout	Timeout during communication after successfully connecting (in seconds).
writable	Is this a WritableDatabase?
flags	Xapian::DB_RETRY_LOCK or 0.

Member Function Documentation

◆ get_tcpcontext()

string RemoteTcpClient::get_tcpcontext	(	const std::string &	hostname,
		int	port
	)

staticprivate

Get a context string for use when constructing Xapian::NetworkError.

Note: this method is used from constructors so has been made static to avoid problems with trying to use uninitialised member variables. In particular, it can't be made a virtual method of the base class.

Definition at line 49 of file remotetcpclient.cc.

References Xapian::Internal::str().

◆ open_socket()

int RemoteTcpClient::open_socket	(	const std::string &	hostname,
		int	port,
		double	timeout_connect
	)

staticprivate

Attempt to open a TCP/IP socket connection to xapian-tcpsrv.

Connect to xapian-tcpsrv running on port port of host hostname. Give up trying to connect after timeout_connect seconds.

Note: this method is called early on during class construction before any member variables or even the base class have been initialised. To help avoid accidentally trying to use member variables or call other methods which do, this method has been deliberately made "static".
