Constructor Details

SimpleStep

public SimpleStep(String aCasProcessorKey)

Creates a new SimpleStep

Parameters:

aCasProcessorKey - 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 Details

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.

Parameters:

aKey - an Analysis Engine key. This must be one of the keys in the FlowController's FlowControllerContext.getAnalysisEngineMetaDataMap().
