<p>Models of the CallPolicies concept are used to specialize the
|
||||
behavior of Python callable objects generated by Boost.Python to
|
||||
wrapped C++ objects like function and member function
|
||||
pointers, providing three behaviors:
|
||||
<ol>
|
||||
<li> <code>precall</code> - Python argument tuple management before
|
||||
the wrapped object is invoked
|
||||
<li> <code>result_converter</code> - C++ return value handling
|
||||
<li> <code>postcall</code> - Python argument tuple and result
|
||||
management after the wrapped object is invoked

|

|
||||
In order to allow the use of multiple models of CallPolicies in the
|
||||
same callable object, Boost.Python's CallPolicies class templates
|
||||
provide a chaining interface which allows them to be recursively
|
||||
composed. This interface takes the form of an optional template
|
||||
parameter, <code>Base</code> which defaults to <a
|
||||
href="default_call_policies.html#default_call_policies-spec">
|
||||
<code>default_call_policies</code></a>. By convention, the
|
||||
<code>precall</code> function of the
|
||||
<code>Base</code> is invoked <i>after</i> the <code>precall</code>
|
||||
function supplied by the outer template, and the <code>postcall</code>
|
||||
function of the <code>Base</code> is invoked <i>before</i> the
|
||||
<code>postcall</code> function of the outer template. If a
|
||||
<code>result_converter</code> is supplied by the outer template, it
|
||||
<i>replaces</i> any <code>result_converter</code> supplied by the
|
||||
<code>Base</code>. For an example, see <a

By convention, the <code>precall</code> function of the <code>Base</code>
