Examples of org.apache.uima.analysis_engine.AnalysisEngineDescription

org.apache.uima.analysis_engine.AnalysisEngineDescription
An AnalysisEngineDescription contains all of the information needed to instantiate and use an {@link org.apache.uima.analysis_engine.AnalysisEngine}.
The {@link org.apache.uima.UIMAFramework#produceAnalysisEngine(ResourceSpecifier)} factory methodis used to create an AnalysisEngine instance from a AnalysisEngineDescription. This insulates applications from knowledge of the particular AnalysisEngine implementation being used.
The AnalysisEngine Description contains the following information:
For a Primitive AnalysisEngine:
- Name of main annotator class
For an Aggregate AnalysisEngine:
- A set of Resource Specifiers that specify the component AnalysisEngines that comprise the aggregate.
- Optionally, a Resource Specifier for the FlowController component that determines routing of the CAS to the component AnalysisEngines.
For All AnalysisEngines:
- A set of Resource Specifiers that specify the external resources needed by this AnalysisEngine.
- {@link AnalysisEngineMetaData Metadata} for this AnalysisEngine - this includes thecapabilities of this AnalysisEngine, the TypeSystem used by this AnalysisEngine, and other parameters.
