    • getFields

      List<JsonPointer> getFields()
      Description copied from interface: Request
      Returns the list of fields which should be included with each JSON resource returned by this request. The returned list may be modified if permitted by this query request. An empty list indicates that all fields should be included.

      NOTE: field filtering alters the structure of a JSON resource and MUST only be performed once while processing a request. It is therefore the responsibility of front-end implementations (e.g. HTTP listeners, Servlets, etc) to perform field filtering. Request handler and resource provider implementations SHOULD NOT filter fields, but MAY choose to optimise their processing in order to return a resource containing only the fields targeted by the field filters.

      Specified by:
      getFields in interface Request
      Returns:
      The list of fields which should be included with each JSON resource returned by this request (never null).

    • getResourcePath

      String getResourcePath()
      Description copied from interface: Request

      NOTE: for resource provider implementations the resource path is relative to the current resource being accessed. See the description of UriRouterContext for more information.

      Specified by:
      getResourcePath in interface Request
      Returns:
      The non-null path of the JSON resource to which this request should be targeted, which may be the empty string.
    • getResourcePathObject

      ResourcePath getResourcePathObject()
      Description copied from interface: Request
      Returns the non-null path of the JSON resource to which this request should be targeted. The resource path is relative and never begins or ends with a forward slash, but may be empty.

    • getRevision

      String getRevision()
      Returns the expected version information associated with the JSON resource to be patched. Version information can be used in order to implement multi-version concurrency control (MVCC).

      The returned version information may be null indicating that the client does not care if the resource has been modified concurrently. If the version information is non-null, and it does not match the current version of the targeted JSON resource, then the patch request will be rejected by the provider.
