$Log: Acquisition.c,v $
Revision 1.23 1998/11/17 19:47:59 jim
A typo probably caused __delitem__
calls on wrapped mapping objects to fail.
Revision 1.22 1998/05/20 17:17:17 jim
Fixed a bug in aq_acquire machinery. If aq_self was a wrapper,
then aq_acquire needed to be called on it, but that wasn't hapenning.
Revision 1.21 1998/05/07 22:10:49 jim
Added aq_inContextOf method.
Changed the way wrapping is done when getting an explicitly-wrapped
object from an implicitly-wrapped object to avoid an extra level of
wrapping.
Fixed a bug that prevented propigation of some filtering errors.
Revision 1.20 1998/04/08 14:50:51 jim
No longer acquire __roles__ explicitly.
Revision 1.19 1998/03/24 16:23:19 jim
Added parens to make gcc SHUT UP!
Revision 1.18 1998/03/24 16:21:17 jim
Fixed bad return in wrapper special.
Revision 1.17 1998/03/24 16:17:01 jim
Rearranged.
Revision 1.16 1998/03/23 20:23:35 jim
Added lots of new machinery to handle wrapping of acquired objects.
Revision 1.15 1998/01/21 19:00:48 jim
Fixed __len__ bugs and added free lists for methods and wrappers
Revision 1.14 1998/01/05 13:38:31 jim
Added special module variable, 'Acquired'. If the value of this
variable is assigned to an attribute, then the value of the attribute
will be acquired, even if it might not otherwize be acquired.
Revision 1.13 1997/11/19 13:51:14 jim
Extended compile option to implicitly acquire __roles__ to
implicitly acquire roles even for explicit acquirers.
Revision 1.12 1997/11/19 13:39:32 jim
Changed filter machinery so that wrapped objects are used as
inst and parent in filter.
Revision 1.11 1997/11/07 19:00:34 jim
Added compile option to implicitly acquire __roles__.
Revision 1.10 1997/10/28 22:09:17 jim
Added another argument to the aq_acquire filter signature.
Changed name of acquire method to aq_acquire. Explicit.acquire is
an alias.
Revision 1.9 1997/10/28 19:36:46 jim
Changed semantics is acquire method:
- Available for Implicit and Explicit,
- Does not filter names with leading underscore,
- Accepts optional 'filter' and 'extra' arguments. If 'filter'
is provided, then it must be a callable object and it is
called with five arguments:
orig -- The original (unwrapped) object
inst -- The object in which an attribute is found
name -- The attribute name
v -- The attribute value
extra -- The 'extra' value passed to 'acquire' or None.
The filter function should return 1 if the attribute should
be returned by acquire and 0 otherwise. It may also raise an
error, in which case the error is propigated.
Revision 1.8 1997/07/02 20:15:27 jim
Added stupid parens to make 'gcc -Wall -pedantic' and Barry happy.
Revision 1.6 1997/06/19 19:31:39 jim
Added ident string.
Revision 1.5 1997/06/19 19:24:21 jim
Many fixes and consolodation with Xaq.
Revision 1.3 1997/02/19 22:30:33 jim
Added $#@! missing static declaration.
Revision 1.2 1997/02/17 16:20:11 jim
Fixed bug in mix-in class declaration.
Added __version__.

Implementing base extension classes
A base extension class is implemented in much the same way that an
extension type is implemented, except:
- The include file, 'ExtensionClass.h', must be included.
- The type structure is declared to be of type
'PyExtensionClass', rather than of type 'PyTypeObject'.
- The type structure has an additional member that must be defined
after the documentation string. This extra member is a method chain
('PyMethodChain') containing a linked list of method definition
('PyMethodDef') lists. Method chains can be used to implement
method inheritance in C. Most extensions don't use method chains,
but simply define method lists, which are null-terminated arrays
of method definitions. A macro, 'METHOD_CHAIN' is defined in
'ExtensionClass.h' that converts a method list to a method chain.
(See the example below.)
- Module functions that create new instances must be replaced by an
'__init__' method that initializes, but does not create storage for
instances.
- The extension class must be initialized and exported to the module
with::
PyExtensionClass_Export(d,"name",type);
where 'name' is the module name and 'type' is the extension class
type object.
Attribute lookup
Attribute lookup is performed by calling the base extension class
'getattr' operation for the base extension class that includes C
data, or for the first base extension class, if none of the base
extension classes include C data. 'ExtensionClass.h' defines a
macro 'Py_FindAttrString' that can be used to find an object's
attributes that are stored in the object's instance dictionary or
in the object's class or base classes::
v = Py_FindAttrString(self,name);
In addition, a macro is provided that replaces 'Py_FindMethod'
calls with logic to perform the same sort of lookup that is
provided by 'Py_FindAttrString'.
Linking
The extension class mechanism was designed to be useful with
dynamically linked extension modules. Modules that implement
extension classes do not have to be linked against an extension
class library. The macro 'PyExtensionClass_Export' imports the
'ExtensionClass' module and uses objects imported from this module
to initialize an extension class with necessary behavior.

$Log: ExtensionClass.h,v $
Revision 1.11 1998/03/23 23:05:09 jim
Updated doc.
Revision 1.10 1998/03/13 22:19:04 jim
Added an interface for testing subclass relationships.
Added macro to test whether ExtensionClass has been imported and
import it if it hasn't been. This is handy in cases where extension
modules are implemented in multiple C files.
Revision 1.9 1997/12/11 15:37:54 jim
Added EXTENSIONCLASS_BASICNEW_FLAG.
Revision 1.8 1997/07/02 20:18:20 jim
Added stupid parens and other changes to make 'gcc -Wall -pedantic'
and Barry happy. Renamed PyCObject_Import to avoid conflict with
version in 1.5.
Revision 1.7 1997/07/02 17:32:34 jim
*** empty log message ***
Revision 1.6 1997/04/11 21:47:51 jim
Got rid of class attributes.
Added method hooks.
Revision 1.5 1997/03/08 12:44:13 jim
Moved INSTANCE_DICT macro to public interface.
Revision 1.4 1997/02/17 16:26:59 jim
Many changes in access to CAPI.
Revision 1.3 1996/12/06 17:13:17 jim
Added support for attro functions and made use of cobject to export C
interfaces.
Revision 1.2 1996/11/08 22:07:26 jim
Added parens in if to make -Wall happy.
Revision 1.1 1996/10/22 22:25:43 jim

$Log: Acquisition.c,v $
Revision 1.23 1998/11/17 19:47:59 jim
A typo probably caused __delitem__
calls on wrapped mapping objects to fail.
Revision 1.22 1998/05/20 17:17:17 jim
Fixed a bug in aq_acquire machinery. If aq_self was a wrapper,
then aq_acquire needed to be called on it, but that wasn't hapenning.
Revision 1.21 1998/05/07 22:10:49 jim
Added aq_inContextOf method.
Changed the way wrapping is done when getting an explicitly-wrapped
object from an implicitly-wrapped object to avoid an extra level of
wrapping.
Fixed a bug that prevented propigation of some filtering errors.
Revision 1.20 1998/04/08 14:50:51 jim
No longer acquire __roles__ explicitly.
Revision 1.19 1998/03/24 16:23:19 jim
Added parens to make gcc SHUT UP!
Revision 1.18 1998/03/24 16:21:17 jim
Fixed bad return in wrapper special.
Revision 1.17 1998/03/24 16:17:01 jim
Rearranged.
Revision 1.16 1998/03/23 20:23:35 jim
Added lots of new machinery to handle wrapping of acquired objects.
Revision 1.15 1998/01/21 19:00:48 jim
Fixed __len__ bugs and added free lists for methods and wrappers
Revision 1.14 1998/01/05 13:38:31 jim
Added special module variable, 'Acquired'. If the value of this
variable is assigned to an attribute, then the value of the attribute
will be acquired, even if it might not otherwize be acquired.
Revision 1.13 1997/11/19 13:51:14 jim
Extended compile option to implicitly acquire __roles__ to
implicitly acquire roles even for explicit acquirers.
Revision 1.12 1997/11/19 13:39:32 jim
Changed filter machinery so that wrapped objects are used as
inst and parent in filter.
Revision 1.11 1997/11/07 19:00:34 jim
Added compile option to implicitly acquire __roles__.
Revision 1.10 1997/10/28 22:09:17 jim
Added another argument to the aq_acquire filter signature.
Changed name of acquire method to aq_acquire. Explicit.acquire is
an alias.
Revision 1.9 1997/10/28 19:36:46 jim
Changed semantics is acquire method:
- Available for Implicit and Explicit,
- Does not filter names with leading underscore,
- Accepts optional 'filter' and 'extra' arguments. If 'filter'
is provided, then it must be a callable object and it is
called with five arguments:
orig -- The original (unwrapped) object
inst -- The object in which an attribute is found
name -- The attribute name
v -- The attribute value
extra -- The 'extra' value passed to 'acquire' or None.
The filter function should return 1 if the attribute should
be returned by acquire and 0 otherwise. It may also raise an
error, in which case the error is propigated.
Revision 1.8 1997/07/02 20:15:27 jim
Added stupid parens to make 'gcc -Wall -pedantic' and Barry happy.
Revision 1.6 1997/06/19 19:31:39 jim
Added ident string.
Revision 1.5 1997/06/19 19:24:21 jim
Many fixes and consolodation with Xaq.
Revision 1.3 1997/02/19 22:30:33 jim
Added $#@! missing static declaration.
Revision 1.2 1997/02/17 16:20:11 jim
Fixed bug in mix-in class declaration.
Added __version__.

Implementing base extension classes
A base extension class is implemented in much the same way that an
extension type is implemented, except:
- The include file, 'ExtensionClass.h', must be included.
- The type structure is declared to be of type
'PyExtensionClass', rather than of type 'PyTypeObject'.
- The type structure has an additional member that must be defined
after the documentation string. This extra member is a method chain
('PyMethodChain') containing a linked list of method definition
('PyMethodDef') lists. Method chains can be used to implement
method inheritance in C. Most extensions don't use method chains,
but simply define method lists, which are null-terminated arrays
of method definitions. A macro, 'METHOD_CHAIN' is defined in
'ExtensionClass.h' that converts a method list to a method chain.
(See the example below.)
- Module functions that create new instances must be replaced by an
'__init__' method that initializes, but does not create storage for
instances.
- The extension class must be initialized and exported to the module
with::
PyExtensionClass_Export(d,"name",type);
where 'name' is the module name and 'type' is the extension class
type object.
Attribute lookup
Attribute lookup is performed by calling the base extension class
'getattr' operation for the base extension class that includes C
data, or for the first base extension class, if none of the base
extension classes include C data. 'ExtensionClass.h' defines a
macro 'Py_FindAttrString' that can be used to find an object's
attributes that are stored in the object's instance dictionary or
in the object's class or base classes::
v = Py_FindAttrString(self,name);
In addition, a macro is provided that replaces 'Py_FindMethod'
calls with logic to perform the same sort of lookup that is
provided by 'Py_FindAttrString'.
Linking
The extension class mechanism was designed to be useful with
dynamically linked extension modules. Modules that implement
extension classes do not have to be linked against an extension
class library. The macro 'PyExtensionClass_Export' imports the
'ExtensionClass' module and uses objects imported from this module
to initialize an extension class with necessary behavior.

Revision 1.11 1998/03/23 23:05:09 jim
Updated doc.
Revision 1.10 1998/03/13 22:19:04 jim
Added an interface for testing subclass relationships.
Added macro to test whether ExtensionClass has been imported and
import it if it hasn't been. This is handy in cases where extension
modules are implemented in multiple C files.
Revision 1.9 1997/12/11 15:37:54 jim
Added EXTENSIONCLASS_BASICNEW_FLAG.
Revision 1.8 1997/07/02 20:18:20 jim
Added stupid parens and other changes to make 'gcc -Wall -pedantic'
and Barry happy. Renamed PyCObject_Import to avoid conflict with
version in 1.5.
Revision 1.7 1997/07/02 17:32:34 jim
*** empty log message ***
Revision 1.6 1997/04/11 21:47:51 jim
Got rid of class attributes.
Added method hooks.

Many changes in access to CAPI.
Revision 1.3 1996/12/06 17:13:17 jim
Added support for attro functions and made use of cobject to export C
interfaces.
Revision 1.2 1996/11/08 22:07:26 jim
Added parens in if to make -Wall happy.
