            <strong>Class</strong> encapsulating type
            information for method arguments and return
            value. It is used as a component of
            <a rel="gsdoc" href="NSInvocation.html#class$NSInvocation">NSInvocation</a>

              to implement message forwarding, such as within the
              distributed objects framework. Instances can
              be obtained from the
              <a rel="gsdoc" href="NSObject.html#class$NSObject">NSObject</a>

                method
                <a rel="gsdoc" href="NSObject.html#method$NSObject-methodSignatureForSelector$">[NSObject -methodSignatureForSelector:]</a>

                Basically, types are represented as
                Objective-C <code>@encode(...)</code>
                compatible strings. The arguments are
                numbered starting from 0, including the
                implicit arguments <code><em>self</em></code>
                (type <code><strong>id</strong></code>, at
                position 0) and <code><em>_cmd</em></code>
                (type <code><strong>SEL</strong></code>, at
                position 1).
