Examples of org.carrot2.core.Controller.process()

org.carrot2.core.Controller.process()
Convenience method for performing processing with the provided query and number of results. The typical use cases for this method is fetching the specified number of results from an {@link IDocumentSource} and, optionally, clustering them with an{@link IClusteringAlgorithm}.
For a method allowing to pass more attributes, see: {@link #process(Map,Class)}.
@param query the query to use during processing @param results the number of results to fetch. If null is provided,the default number of results will be requested. @param processingComponentClasses classes of components to perform processing inthe order they should be arranged in the pipeline. Each provided class must implement {@link IProcessingComponent}. @return results of the processing
