\modulesynopsis{Interface to the creation of runtime implementation objects.}
|
||
|
|
|
||
|
|
|
||
|
|
The \module{new} module allows an interface to the interpreter object
|
||
|
|
creation functions. This is for use primarily in marshal-type functions,
|
||
|
|
when a new object needs to be created ``magically'' and not by using the
|
||
|
|
regular creation functions. This module provides a low-level interface
|
||
|
|
to the interpreter, so care must be exercised when using this module.
|
||
|
|
|
||
|
|
The \module{new} module defines the following functions:
|
||
|
|
|
||
|
|
\begin{funcdesc}{instance}{class, dict}
|
||
|
|
This function creates an instance of \class{class} with dictionary
|
||
|
|
\var{dict} without calling the \method{__init__()} constructor. Note that
|
||
|
|
this means that there are no guarantees that the object will be in a
|
||
|
|
consistent state.
|
||
|
|
|
||
|
|
Arguments are \emph{not} type-checked, and an incorrectly typed argument
|
||
|
|
will result in undefined behaviour.
|
||
|
|
\end{funcdesc}
|
||
|
|
|
||
|
|
\begin{funcdesc}{instancemethod}{function, instance, class}
|
||
|
|
This function will return a method object, bound to \var{instance}, or
|
||
|
|
unbound if \var{instance} is \code{None}. It is checked that
|
||
|
|
\var{function} is callable, and that \var{instance} is an instance
|
||
|
|
object or \code{None}.
|
||
|
|
\end{funcdesc}
|
||
|
|
|
||
|
|
\begin{funcdesc}{function}{code, globals\optional{, name\optional{argdefs}}}
|
||
|
|
Returns a (Python) function with the given code and globals. If
|
||
|
|
\var{name} is given, the function will have the given name. If
|
||
|
|
\var{argdefs} is given, they will be the function defaults.
|
||
|
|
\end{funcdesc}
|
||
|
|
|
||
|
|
\begin{funcdesc}{code}{argcount, nlocals, stacksize, flags, codestring,
|
||
|
|
constants, names, varnames, filename, name, firstlineno,
|
||
|
|
lnotab}
|
||
|
|
This function is an interface to the \cfunction{PyCode_New()} internal
|
||
|
|
function.
|
||
|
|
XXX This is still undocumented!!!!!!!!!!!
|
||
|
|
\end{funcdesc}
|
||
|
|
|
||
|
|
\begin{funcdesc}{module}{name}
|
||
|
|
This function returns a new module object with name \var{name}.
|
||
|
|
\var{name} should be a string.
|
||
|
|
\end{funcdesc}
|
||
|
|
|
||
|
|
\begin{funcdesc}{classobj}{name, baseclasses, dict}
|
||
|
|
This function returns a new class object, with name \var{name}, derived
|
||
|
|
from \var{baseclasses} (which should be a tuple of classes) and with
|
||
|
|
namespace \var{dict}. All parameters are type checked.
|
||
|
|
\end{funcdesc}
