All Implemented Interfaces:

ManagedProvider<SemanticTag,String>, Provider<SemanticTag>, SemanticTagProvider

@NonNullByDefault
public class ManagedSemanticTagProvider
extends AbstractManagedProvider<SemanticTag,String,SemanticTagDTO>
implements SemanticTagProvider

ManagedSemanticTagProvider is an OSGi service, that allows to add or remove semantic tags at runtime by calling AbstractManagedProvider.add(E) or AbstractManagedProvider.remove(K). An added semantic tag is automatically exposed to the SemanticTagRegistry. Persistence of added semantic tags is handled by a StorageService.
