"""Manages a dictionary of CLSID strings to Python classes.
|
||
|
|
|
||
|
|
Primary use of this module is to allow modules generated by
|
||
|
|
makepy.py to share classes. @makepy@ automatically generates code
|
||
|
|
which interacts with this module. You should never need to reference
|
||
|
|
this module directly.
|
||
|
|
|
||
|
|
This module only provides support for modules which have been previously
|
||
|
|
been imported. The gencache module provides some support for loading modules
|
||
|
|
on demand - once done, this module supports it...
|
||
|
|
|
||
|
|
As an example, the MSACCESS.TLB type library makes reference to the
|
||
|
|
CLSID of the Database object, as defined in DAO3032.DLL. This
|
||
|
|
allows code using the MSAccess wrapper to natively use Databases.
|
||
|
|
|
||
|
|
This obviously applies to all cooperating objects, not just DAO and
|
||
|
|
Access.
