        immutable map of link parameters.
      • toString

        public abstract String toString()
        Returns a string representation as a link header (RFC 5988). All link params are serialized as link-param="value" where value is a quoted-string. For example, ; title="employee"; rel="manager friend"
        Overrides:
        toString in class Object
        Returns:
        string link header representation for this link.
      • valueOf

        public static Link valueOf(String value)
        Simple parser to convert link header string representations into a link.
         link ::= '<' uri '>' (';' link-param)*
         link-param ::= name '=' quoted-string
         
        See RFC 5988 for more information.
        Parameters:
        value - String representation.
        Returns:
        newly parsed link.
        Throws:
        IllegalArgumentException - if a syntax error is found.
        See Also:
        Link.Builder.link(java.lang.String)
      • fromUri

        public static Link.Builder fromUri(URI uri)
        Create a new builder instance initialized from an existing URI.
        Parameters:
        uri - a URI that will be used to initialize the builder.
        Returns:
        a new builder.
        Throws:
        IllegalArgumentException - if uri is null.
      • fromUri

        public static Link.Builder fromUri(String uri)
        Create a new builder instance initialized from an existing URI represented as a string.
        Parameters:
        uri - a URI that will be used to initialize the builder.
        Returns:
        a new builder.
        Throws:
        IllegalArgumentException - if uri is null.
      • fromUriBuilder

        public static Link.Builder fromUriBuilder(UriBuilder uriBuilder)
        Create a new builder instance initialized from a URI builder.
        Parameters:
        uriBuilder - instance of URI builder.
        Returns:
        a new builder.
      • public static Link.Builder fromLink(Link link)
        Create a new builder instance initialized from another link.
        Parameters:
        link - other link used for initialization.
        Returns:
        a new builder.
      • fromPath

        public static Link.Builder fromPath(String path)
        Convenience method to build a link from a path. Equivalent to fromUriBuilder(UriBuilder.fromPath(path)).
        Parameters:
        path - a URI path that will be used to initialize the Link, may contain URI template parameters.
        Returns:
        a new Link.Builder.
        Throws:
        IllegalArgumentException - if path is null.
      • fromResource

        public static Link.Builder fromResource(Class<?> resource)
        Convenience method to build a link from a resource. Equivalent to Link.fromUriBuilder(UriBuilder.fromResource(resource)). Note that the link URI passed to the Link.Builder instance returned by this method is relative. Should the link be built as absolute, a base URI has to be specified in the builder prior to building the new link instance. For example, on a server side a UriInfo.getBaseUri() may be typically used to define the base URI of a link created using this method.
        Parameters:
        resource - a root resource whose Path value will be used to initialize the builder.
        Returns:
        a new link builder instance.
        Throws:
        IllegalArgumentException - if resource is not annotated with Path or resource is null.
        See Also:
        UriInfo.getBaseUri()
      • fromMethod

        public static Link.Builder fromMethod(Class<?> resource,
                                              String method)
        Convenience method to build a link from a resource. Equivalent to Link.fromUriBuilder(UriBuilder.fromMethod(resource, method)). Note that the link URI passed to the Link.Builder instance returned by this method is relative. Should the link be built as absolute, a base URI has to be specified in the builder prior to building the new link instance. For example, on a server side a UriInfo.getBaseUri() may be typically used to define the base URI of a link created using this method.
        Parameters:
        resource - the resource containing the method.
        method - the name of the method whose Path value will be used to obtain the path to append.
        Returns:
        the updated Link.Builder.
        Throws:
        IllegalArgumentException - if resource or method is null, or there is more than or less than one variant of the method annotated with Path.
        See Also:
        UriInfo.getBaseUri()
