public class SimpleStep
extends Step

Indicates that a CAS should be routed to a single AnalysisEngine. After it has been processed, the Flow.next() method will be called again to determine the next destination for the CAS.

Constructor Summary

SimpleStep(String aCasProcessorKey)
Creates a new SimpleStep

Method Summary

String	getAnalysisEngineKey() Gets the key of the Analysis Engine to which the CAS should be routed.
void	setAnalysisEngineKey(String aKey) Sets the key of the Analysis Engine to which the CAS should be routed.

Constructor Detail

SimpleStep

public SimpleStep(String aCasProcessorKey)

Creates a new SimpleStep

Parameters:

aAnalysisEngineKey - The key of the Analysis Engine to which the CAS should be routed. This must be one of the keys in the FlowController's FlowControllerContext.getAnalysisEngineMetaDataMap().

Method Detail

getAnalysisEngineKey

public String getAnalysisEngineKey()

Gets the key of the Analysis Engine to which the CAS should be routed.

Returns:

an AnalysisEngine key

setAnalysisEngineKey

public void setAnalysisEngineKey(String aKey)

Sets the key of the Analysis Engine to which the CAS should be routed. By using this method, a user's Flow implementation can (but is not required to) reuse the same SimpleStep object multiple times.
