java.lang.Object

it.uniroma2.art.semanticturkey.services.core.projects.PreloadedDataStore

@Component
public class PreloadedDataStore
extends Object

A singleton component that is in charge of storing preloaded data, while assuring that they will be eventually deleted. The current implementation does not guarantee the deletion of the stored data in case of abrupt termination of the program. For this case, it relies on the automatic clearing of the temporary directory where this store places its data.
