<h3><a name="tuple-spec"></a>Class <code>tuple</code></h3>

<p>Exposes the interface of Python's built-in <code>tuple</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>tuple</code> is publicly derived from <code><a
|
|
href="object.html#object-spec">object</a></code>, the public object
|
|
interface applies to <code>tuple</code> instances as well.</p>
