Detailed Description

A pipeline element the runs a filter plugin.

Constructor & Destructor Documentation

PipelineFilter()

PipelineFilter::PipelineFilter	(	const std::string &	name,
		const ConfigCategory &	filterDetails
	)

Construct the PipelineFilter class.

This is the specialisation of the PipelineElement that represents a running filter in the pipeline.

Member Function Documentation

init()

bool PipelineFilter::init ( OUTPUT_HANDLE *  outHandle, OUTPUT_STREAM  output  )

virtual

Initialise the pipeline filter ready for ingest of data.

Parameters

outHandle	The pipeline element we are sending the data to
output

Implements PipelineElement.

setup()

bool PipelineFilter::setup ( ManagementClient *  mgmt, void *  ingest, std::map< std::string, PipelineElement *> &  categories  )

virtual

Setup the configuration categories for the filter element in a pipeline.

Parameters

mgmt	The Management client
ingest	The service handler for our service
filterCatiegories	A map of the category name to pipeline element

Implements PipelineElement.

setupConfiguration()

bool PipelineFilter::setupConfiguration ( ManagementClient *  mgtClient, std::vector< std::string > &  children  )

virtual

Setup the configuration for a filter in a pipeline.

Parameters

mgtClient	The managament client
children	A vector to fill with child configuration categories

Reimplemented from PipelineElement.

shutdown()

void PipelineFilter::shutdown ( ServiceHandler *  serviceHandler, ConfigHandler *  configHandler  )

virtual

Shutdown a pipeline element that is a filter.

Remove registration for categories of interest, persist and plugin data that needs persisting and call shutdown on the plugin itself.

Parameters

serviceHandler	The service handler of the service that is hostign the pipeline
configHandler	The config handler for the service from which we unregister

Implements PipelineElement.
