| <h3><a name="dict-spec"></a>Class <code>dict</code></h3> |
| |
| <p>Exposes the <a href= |
| "http://www.python.org/dev/doc/devel/lib/typesmapping.html">mapping |
| protocol</a> of Python's built-in <code>dict</code> type. The semantics |
| of the constructors and member functions defined below can be fully |
| understood by reading the <a href= |
| "ObjectWrapper.html#TypeWrapper-concept">TypeWrapper</a> concept |
| definition. Since <code>dict</code> is publicly derived from <code><a |
| href="object.html#object-spec">object</a></code>, the public object |
| interface applies to <code>dict</code> instances as well.</p> |
