Interface IPipeline

All Known Implementing Classes:

Pipeline

public interface IPipeline

Common set of methods to drive an event-driven process. A pipeline is made of a chain of IPipelineStep objects through which documents are processed.

Method Summary

void	addStep(IPipelineStep step) Adds a step to this pipeline.
void	cancel() Cancels processing on this pipeline.
void	clearSteps() Remove all the IPipelineSteps from the pipeline.
void	destroy() Frees all resources from all steps in this pipeline.
void	endBatch() Finishes a batch of inputs.
java.lang.String	getId() Get the Pipelines identifier.
PipelineReturnValue	getState() Gets the current pipeline state.
java.util.List<IPipelineStep>	getSteps() Gets the list of all steps in this pipeline.
void	process(Event input) Starts IPipeline processing with a Event as input.
void	process(RawDocument input) Starts IPipeline processing with a RawDocument as input.
void	setId(java.lang.String id) Set the pipelines identifier.
void	startBatch() Starts a batch of inputs.

Method Detail

process

void process(RawDocument input)

Starts IPipeline processing with a RawDocument as input. This is a convenience method that calls process(Event).

Parameters:

input - the RawDocument to process.

process

void process(Event input)

Starts IPipeline processing with a Event as input.

Parameters:

input - event that primes the IPipeline

getState

PipelineReturnValue getState()

Gets the current pipeline state.

Returns:

the current state of the pipeline.

cancel

void cancel()

Cancels processing on this pipeline.

addStep

void addStep(IPipelineStep step)

Adds a step to this pipeline. Steps are executed in the order they are added.

Parameters:

step - the step to add.

getSteps

java.util.List<IPipelineStep> getSteps()

Gets the list of all steps in this pipeline.

Returns:

a list of all steps in this pipeline, the list may be empty.

startBatch

void startBatch()

Starts a batch of inputs.

endBatch

void endBatch()

Finishes a batch of inputs.

destroy

void destroy()

Frees all resources from all steps in this pipeline.

clearSteps

void clearSteps()

Remove all the IPipelineSteps from the pipeline. Also calls the destroy() method on each step.

setId

void setId(java.lang.String id)

Set the pipelines identifier.

getId

java.lang.String getId()

Get the Pipelines identifier.

Returns:

String identifier
