Detailed Description

A socket connection strategy determines how to connect a socket in the face of DNS resolution, when an IP may resolve to more than one IP address.

Provided concrete classes handle single, multiple+synchronous, and multiple+multithreaded approaches.

Member Function Documentation

virtual void VSocketConnectionStrategy::connect	(	const VString &	hostName,
		int	portNumber,
		VSocket &	socketToConnect
	)		const [pure virtual]

The VSocketConnectionStrategy interface to be implemented by concrete subclasses.

Connects to the host name by resolving it and then applying the strategy to the resolved IP addresses. If the strategy fails (for whatever reason, be it a connect failure or a timeout) it shall throw a VException.

Parameters:

hostName	the name to resolve and connect to
portNumber	the port number to connect to
socketToConnect	if successful, this Vault socket object is to be mutated upon return to have the connected socket's host IP address and low-level VSocketID; for simple non-threaded strategies it is acceptable to simply call this object's connectToIPAddress() and leave the results in place if successful

Implemented in VSocketConnectionStrategyThreaded, VSocketConnectionStrategyLinear, and VSocketConnectionStrategySingle.
