org.dspace.app.iiif.service.ManifestService

@RequestScope
@Component
public class ManifestService
extends AbstractResourceService

This service creates the manifest. There should be a single instance of this service per request. The @RequestScope provides a single instance created and available during complete lifecycle of the HTTP request. This is needed because some configurations are cached in the instance. Moreover, many injected dependencies are also request scoped or prototype (that will turn in a request scope when injected in a request scope bean). The generators for top-level domain objects need to be request scoped as they act as a builder storing the object state during each incremental building step until the final object is returned (IIIF Resource).
