Handler Architecture

Handlers are positioned between the Registry and the rest of the backend:

  • Repository
  • Version Repository
  • Data Access Layer

From the perspective of the processing flow, the Registry invokes all the handlers (until a handler indicates that the processing is complete) before delegating resource related requests to the Repository and VersionRepository components. Therefore, handlers can provide completely customized behavior to the normal processing of resources. This is illustrated in the following figure.
