\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\optional{, dict}}
|
|
This function creates an instance of \var{class} with dictionary
|
|
\var{dict} without calling the \method{__init__()} constructor. If
|
|
\var{dict} is omitted or \code{None}, a new, empty dictionary is
|
|
created for the new instance. Note that there are no guarantees that
|
|
the object will be in a consistent state.
|
|
\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}. \var{function} must be
|
|
callable, and \var{instance} must be 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, it must be a string or \code{None}. If it is a
|
|
string, the function will have the given name, otherwise the function
|
|
name will be taken from \code{\var{code}.co_name}. If
|
|
\var{argdefs} is given, it must be a tuple and will be used to
|
|
determine the default values of parameters.
|
|
\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()} C
|
|
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} must 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}.
|
|
\end{funcdesc}
