org.jamesii.core.experiments.tasks.IInitializedComputationTask
A computation task which has been setup by a corresponding factory. An initialized computation task wraps a "computation tasks" and adds information about its runtime behavior. Thus, whichever computation task is being instantiated by a class implementing this interface, the class should make sure that run time information is collected and provided via the {@link #getRunInfo()}. @author Jan Himmelspach
