org.apache.stanbol.enhancer.servicesapi.EnhancementEngine.canEnhance()
Indicate if this engine can enhance supplied ContentItem, and if it suggests enhancing it synchronously or asynchronously. The {@link EnhancementJobManager} can force sync/async mode if desired, it isjust a suggestion from the engine.
This method is expected to execute fast and MUST NOT change the parsed {@link ContentItem}. It is called with a read lock on the ContentItem.
NOTE: Returning {@link #CANNOT_ENHANCE} will cause the {@link EnhancementJobManager} to skip the execution of this Engine. Ifan {@link EngineException} is thrown the executed {@link Chain} willfail (unless this engine is marked as OPTIONAL). @param ci The ContentItem to enhance @throws EngineException if the introspecting process of the content itemfails
