@PublicApi
public class ReusablePluginWorkUnit
extends PluginWorkUnit

Work unit performing plugin calculation. The input is a {plugin object, input molecule} array, the plugin is supposed to be coming from a ReusableInputProducer and returned by getResult(). The calculation result should be fetched from the plugin later in the application and returned to the input producer by calling ReusableInputProducer.reuse(java.lang.Object). You can use a CompositeInputProducer composed of a ReusableInputProducer and a MolInputProducer to provide the input for this work unit.
