226 | The <code class="computeroutput"><span class="identifier">normalise</span></code> class template | |
227 | converts one instantiation of the <code class="computeroutput"><span class="identifier">policy</span></code> | |
228 | class into a normalised form. This is used internally to reduce code bloat: | |
229 | so that instantiating a special function on <code class="computeroutput"><span class="identifier">policy</span><span class="special"><</span><span class="identifier">A</span><span class="special">,</span><span class="identifier">B</span><span class="special">></span></code> or | |
230 | <code class="computeroutput"><span class="identifier">policy</span><span class="special"><</span><span class="identifier">B</span><span class="special">,</span><span class="identifier">A</span><span class="special">></span></code> actually both generate the same code | |
231 | internally. | |
232 | </p> | |
233 | <p> | |
234 | Further more, <code class="computeroutput"><span class="identifier">normalise</span></code> can | |
235 | be used to combine a policy with one or more policies: for example many of | |
236 | the special functions will use this to set policies which they don't make | |
237 | use of to their default values, before forwarding to the actual implementation. | |
238 | In this way code bloat is reduced, since the actual implementation depends | |
239 | only on the policy types that they actually use. | |
