      • selectVariant

        public Variant selectVariant​(List<Variant> variants)
                              throws IllegalArgumentException
        Description copied from interface: Request
        Select the representation variant that best matches the request. Returns null in case there is no matching variant in the list.

        More explicit variants are chosen ahead of less explicit ones. A vary header is computed from the supplied list and automatically added to the response.

        Specified by:
        selectVariant in interface Request
        Parameters:
        variants - a list of Variant that describe all of the available representation variants.
        Returns:
        the variant that best matches the request or null if there's no match.
        Throws:
        IllegalArgumentException - if variants is empty or null.

      • evaluatePreconditions

        public Response.ResponseBuilder evaluatePreconditions​(EntityTag eTag)
        Description copied from interface: Request
        Evaluate request preconditions based on the passed in value.
        Specified by:
        evaluatePreconditions in interface Request
        Parameters:
        eTag - an ETag for the current state of the resource
        Returns:
        null if the preconditions are met or a ResponseBuilder set with the appropriate status if the preconditions are not met. A returned ResponseBuilder will include an ETag header set with the value of eTag, provided none of the precondition evaluation has failed, in which case the ETag header would not be included and the status code of the returned ResponseBuilder would be set to Response.Status.PRECONDITION_FAILED.
      • evaluatePreconditions

        public Response.ResponseBuilder evaluatePreconditions​(Date lastModified)
        Description copied from interface: Request
        Evaluate request preconditions based on the passed in value.
        Specified by:
        evaluatePreconditions in interface Request
        Parameters:
        lastModified - a date that specifies the modification date of the resource
        Returns:
        null if the preconditions are met or a ResponseBuilder set with the appropriate status if the preconditions are not met.
      • evaluatePreconditions

        public Response.ResponseBuilder evaluatePreconditions​(Date lastModified,
                                                              EntityTag eTag)
        Description copied from interface: Request
        Evaluate request preconditions based on the passed in value.
        Specified by:
        evaluatePreconditions in interface Request
        Parameters:
        lastModified - a date that specifies the modification date of the resource
        eTag - an ETag for the current state of the resource
        Returns:
        null if the preconditions are met or a ResponseBuilder set with the appropriate status if the preconditions are not met. A returned ResponseBuilder will include an ETag header set with the value of eTag, provided none of the precondition evaluation has failed, in which case the ETag header would not be included and the status code of the returned ResponseBuilder would be set to Response.Status.PRECONDITION_FAILED.
      • evaluatePreconditions

        public Response.ResponseBuilder evaluatePreconditions()
        Description copied from interface: Request
        Evaluate request preconditions for a resource that does not currently exist. The primary use of this method is to support the If-Match: * and If-None-Match: * preconditions.

        Note that precondition If-None-Match: something will never be considered to have been met, and it is the application's responsibility to enforce any additional method-specific semantics. E.g. a PUT on a resource that does not exist might succeed whereas a GET on a resource that does not exist would likely result in a 404 response. It would be the responsibility of the application to generate the 404 response.

        Specified by:
        evaluatePreconditions in interface Request
        Returns:
        null if the preconditions are met or a ResponseBuilder set with the appropriate status if the preconditions are not met.
