51Degrees Pipeline for Java

fiftyone.pipeline.engines.flowelements.AspectEngineBase< TData extends AspectData, TProperty extends AspectPropertyMetaData > Class Template Reference abstract

Detailed Description

Base class for AspectEngines to extend.

This implements the data update service and missing property service along with everything already implemented by FlowElementBase.

◆ processEngine()

abstract void fiftyone.pipeline.engines.flowelements.AspectEngineBase< TData extends AspectData, TProperty extends AspectPropertyMetaData >.processEngine ( FlowData   flowData,
TData   aspectData  
) throws Exception
abstract protected

Extending classes must implement this method.

It should perform the required processing and update the specified aspect data instance.

Parameters
flowData - the FlowData instance that provides the evidence
aspectData - the AspectData instance to populate with the results of processing
Exceptions
Exception - if there was an exception during processing

◆ processInternal()

final void fiftyone.pipeline.engines.flowelements.AspectEngineBase< TData extends AspectData, TProperty extends AspectPropertyMetaData >.processInternal ( FlowData   flowData ) throws Exception
protected

Implementation of method from the base class FlowElementBase.

This exists to centralise the results caching logic.

Parameters
flowData - the FlowData instance that provides the evidence and holds the result.
Exceptions
Exception - if there was an exception during processing
