Detailed Description

A pipeline element that represents a branch in the pipeline.

Constructor & Destructor Documentation

~PipelineBranch()

PipelineBranch::~PipelineBranch

(

)

Destructor for the pipeline branch.

If the pipeline is not already shutdown then shut it down Delete the thread if it exists.

Member Function Documentation

ingest()

void PipelineBranch::ingest ( READINGSET *  readingSet )

virtual

Ingest a set of readings and pass on in the pipeline.

Create a deep copy and queue the copy into the branched pipeline.

Parameters

readingSet

The set of readings to ingest

Implements PipelineElement.

init()

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

virtual

Initialise the pipeline branch.

Initialise the elements of the child pipeline Spawn a thread to excute the child pipeline.

Parameters

config	The filter configuration
outHandle	The pipeline element on the "main branch"
output

Implements PipelineElement.

setup()

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

virtual

Setup the configuration categories for the branch element of a pipeline.

The branch itself has no category, but it must call the setup method on all items in the child branch of the piepline.

Parameters

mgmt	The management client
ingest	The configuration handler for our service
filterCategories	A map of the category names to pipeline elements

Implements PipelineElement.

setupConfiguration()

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

virtual

Setup the configuration for a branch in a pipeline.

Parameters

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

Reimplemented from PipelineElement.

shutdown()

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

virtual

Setup the configuration categories for the branch element of a pipeline.

The branch itself has no category, but it must call the setup method on all items in the child branch of the piepline.

Parameters

mgmt	The management client
ingest	The configuration handler for our service
filterCategories	A map of the category names to pipeline elements

Implements PipelineElement.
