Detailed Description

The NorthFilterPipeline class is derived from FilterPipeline class and is used to represent a pipeline of filter applicable to sending process.

Methods are provided to load filters, setup filtering pipeline and for pipeline/filters cleanup.

Constructor & Destructor Documentation

NorthFilterPipeline()

NorthFilterPipeline::NorthFilterPipeline	(	ManagementClient *	mgtClient,
		StorageClient &	storage,
		std::string	serviceName
	)

NorthFilterPipeline class constructor.

This class abstracts the filter pipeline interface for sending process

Parameters

mgtClient	Management client handle
storage	Storage client handle
serviceName	Name of the service to which this pipeline applies

Member Function Documentation

setupFiltersPipeline()

bool NorthFilterPipeline::setupFiltersPipeline	(	void *	passToOnwardFilter,
		void *	useFilteredData,
		void *	_sendingProcess
	)

Set the filter pipeline for sending process.

This method calls the the method "plugin_init" for all loadad filters. Up to date filter configurations and Ingest filtering methods are passed to "plugin_init"

Parameters

passToOnwardFilter	Ptr to function that passes data to next filter
useFilteredData	Ptr to function that gets final filtered data
_sendingProcess	The SendingProcess class handle

Returns

True on success, False otherwise. Any caught exception
