Constructor & Destructor Documentation

SingleThreadedEfViFeedEngine	(	const LoggerSettings &	loggerSettings,
		const std::string &	ifName,
		UInt16	memregSize = 512,
		UInt32	receiveRingSize = 1024 )

Constructor.

Parameters

loggerSettings	Defines feed engine logging settings.
ifName	Network interface card name.
receiveRingSize	Number of buffers in a virtual interface receive ring. Single buffer is used for a single network packet. The receive ring must be capacious enough to place incoming packets during market data bursts.
memregSize	Size of allocated memory in the number of 2Mb pages, each page can fit 1024 packets This memory is used to store packets during packet ordering and recovery for all the client handlers.

~SingleThreadedEfViFeedEngine ( )

override

NetFeedEngineProcessResult process ( )

inline

Carries out pending actions like data retrieval and event dispatching.

This function must be invoked after each handler-associated action (i.e., start, stop).

Note: This function must not be invoked concurrently.; This function must not be invoked as frequent as possible.
