  • Element Details

    • value

      Class<?> value
      The type of entity that should receive links for this service. Defaults to the request's body entity type, or the response entity type if they are not a Collection or a Response.
      Default:
      java.lang.Void.class

    • entityClassName

      String entityClassName
      Default:
      ""

    • rel

      String rel
      The link relation. This defaults as follows:
      list
      GET for ResourceFacade entities or methods that return a Collection
      self
      GET for non-ResourceFacade and non-Collection entities
      remove
      DELETE
      add
      POST
      update
      PUT
      Default:
      ""

    • pathParameters

      String[] pathParameters

      List of path parameter EL from the leftmost URI path parameter to the rightmost. These can be normal constant string values or EL expressions (${foo.bar}) that will resolve using either the default EL context, or the context specified by a @LinkELProvider annotation. The default context resolves any non-qualified variable to properties of the response entity for whom we're discovering links, and has an extra binding for the "this" variable which is the response entity as well.

      If there are too many parameters for the current path, only the leftmost useful ones will be used.

      Defaults to using discovery of values from the entity itself with @ResourceID, @ResourceIDs, JAXB's @XmlID or JPA's @Id and @ParentResource.

      This is not used for ResourceFacade entities, which provide their own list of path parameters.

      Default:
      {}

    • queryParameters

      ParamBinding[] queryParameters

      List of query parameters which should be attached to the link.

      Default:
      {}

    • matrixParameters

      ParamBinding[] matrixParameters

      List of matrix parameters which should be attached to the link.

      Default:
      {}

    • constraint

      String constraint

      EL expression that should return a boolean indicating whether or not this service link should be used. This is useful for security constraints limiting access to resources. Defaults to using the @RolesAllowed annotation using the current SecurityContext to check the current user's permissions.

      This can be a normal constant boolean value ("true" or "false") or an EL expression (${foo.bar}) that will resolve using either the default EL context, or the context specified by a @LinkELProvider annotation.

      For entities that are not ResourceFacade, the default context resolves any non-qualified variable to properties of the response entity for whom we're discovering links, and has an extra binding for the "this" variable which is the response entity as well.

      For entities that are a ResourceFacade, the default context has single binding for the "this" variable which is the ResourceFacade's entity type (Class instance).

      Default:
      ""
