Method Detail

init

protected List<org.wso2.siddhi.query.api.definition.Attribute> init(org.wso2.siddhi.query.api.definition.AbstractDefinition inputDefinition,
                                                                    org.wso2.siddhi.core.executor.ExpressionExecutor[] attributeExpressionExecutors,
                                                                    org.wso2.siddhi.core.util.config.ConfigReader configReader,
                                                                    org.wso2.siddhi.core.config.SiddhiAppContext siddhiAppContext)

The initialization method for StreamProcessor, which will be called before other methods and validate the all configuration and getting the initial values.

Specified by:

init in class org.wso2.siddhi.core.query.processor.stream.StreamProcessor

Parameters:

attributeExpressionExecutors - are the executors of each attributes in the Function

siddhiAppContext - Siddhi app runtime context

process

protected void process(org.wso2.siddhi.core.event.ComplexEventChunk<org.wso2.siddhi.core.event.stream.StreamEvent> streamEventChunk,
                       org.wso2.siddhi.core.query.processor.Processor nextProcessor,
                       org.wso2.siddhi.core.event.stream.StreamEventCloner streamEventCloner,
                       org.wso2.siddhi.core.event.stream.populater.ComplexEventPopulater complexEventPopulater)

Process events received by BayesianRegressionUpdateStreamingProcessorExtension.

Specified by:

process in class org.wso2.siddhi.core.query.processor.stream.StreamProcessor

Parameters:

streamEventChunk - the event chunk that need to be processed

nextProcessor - the next processor to which the success events need to be passed

streamEventCloner - helps to clone the incoming event for local storage or modification

complexEventPopulater - helps to populate the events with the resultant attributes

start

public void start()

This will be called only once and this can be used to acquire required resources for the processing element. This will be called after initializing the system and before starting to process the events.

stop

public void stop()

This will be called only once and this can be used to release the acquired resources for processing. This will be called before shutting down the system.

currentState

public Map<String,Object> currentState()

Used to collect the serializable state of the processing element, that need to be. persisted for reconstructing the element to the same state on a different point of time

Returns:

stateful objects of the processing element as an map

restoreState

public void restoreState(Map<String,Object> state)

Used to restore serialized state of the processing element, for reconstructing. the element to the same state as if was on a previous point of time.

Parameters:

state - the stateful objects of the processing element as a map. This is the same map that is created upon calling currentState() method.
