How do I get type methods?

[yavannadil@yahoo.com]

Hello!

If I do

import uno
localContext=un o.getComponentC ontext()

then localContext is of type <type 'pyuno'>
I guess it's a new type provided by PyUNO extension.
localContext.__ class__ is None
Is there any way to list all methods of that new type, via Python C
API or through interpreter (other then dir(localContex t) )?
What I want is to call localContext's methods like in the tutorial
example:

x=MyClass()
MyClass.f(x)

Thank you,
Dmitri

What's wrong about `dir()`?

I'd prefer::

x = MyClass()
x.f()

I want to cashe pointers to Python functions in a non-Python app.
'dir()' requires an argument, and I want to get function pointers
before I have any variable of given type or class.
That's why 'MyClass.f(x)'
I'm not against 'dir(MyClass)'; the question is, what should I 'dir()'
to get methods of 'pyuno' type instance?

Usually instances don't have its own methods, they get them from the
class. So you actually need dir(MyClass).
Note that dir() might not show all available methods.

Let me retype my question: what I 'dir()' in case of 'pyuno' type
instance?
Or in case of 'dict' type instance? Or in case of any other new python
type?

>>class Foo:

.... def g(self,x):
.... print x-1
....

>>dir(Foo)

['__doc__', '__module__', 'f', 'g']

Is this not what you want? These are the only methods in the Foo
class.

The OPs problem is, there is no access to the class or type because
there is no name. You can get just instances from a factory function.

Perhaps ?

It gives
['__class__', '__cmp__', '__delattr__', '__doc__', '__getattribute __',
'__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__' ,
'__repr__', '__setattr__', '__str__']

while

import sys
dir(type(sys.mo dules))

gives
['__class__', '__cmp__', '__contains__', '__delattr__', '__delitem__',
'__doc__', '__eq__', '__ge__', '__getattribute __', '__getitem__',
'__gt__', '__hash__', '__init__', '__iter__', '__le__', '__len__',
'__lt__', '__ne__', '__new__', '__reduce__', '__reduce_ex__' ,
'__repr__', '__setattr__', '__setitem__', '__str__', 'clear', 'copy',
'fromkeys', 'get', 'has_key', 'items', 'iteritems', 'iterkeys',
'itervalues', 'keys', 'pop', 'popitem', 'setdefault', 'update',
'values']

so I guess PyUNO extension doesn't provide proper introspection :-(

Exactly :-(

You can get just instances from a factory function.

Worse, if I call

localContext.Se rviceManage

I'll get something with different set of methods, but of the same type
- 'pyuno' :-(

'pyuno' objects are proxy objects that represent UNO objects, services,
and interfaces. Since all attribute lookups are handled by the UNO
bridge, the proxy object doesn't actually know what attributes it has,
which is why it won't respond anything useful to the usual dir()
inspection.

To list the methods and properties that the UNO object behind a pyuno
proxy object has, you need to use UNO inspection capabilities. Something
like the following seems to work:

# unodir.py
def unodir(unoobj):
import uno
from com.sun.star.be ans.MethodConce pt import ALL as ALLMETHS
from com.sun.star.be ans.PropertyCon cept import ALL as ALLPROPS
ctx = uno.getComponen tContext()
introspection = ctx.ServiceMana ger.createInsta nceWithContext(
"com.sun.star.b eans.Introspect ion", ctx)
access = introspection.i nspect(unoobj)
meths = access.getMetho ds(ALLMETHS)
props = access.getPrope rties(ALLPROPS)
return [ x.getName() for x in meths ] + [ x.Name for x in props ]

>>import uno
>>from unodir import unodir
>>localContex t = uno.getComponen tContext()
>>unodir(localC ontext)

[u'queryInterfac e', u'acquire', u'release', u'getValueByNam e',
u'getServiceMan ager', u'getElementTyp e', u'hasElements', u'getByName',
u'getElementNam es', u'hasByName', u'replaceByName ', u'insertByName' ,
u'removeByName' , u'getTypes', u'getImplementa tionId', u'queryAdapter' ,
u'dispose', u'addEventListe ner', u'removeEventLi stener',

I suspected something like that, but couldn't quite believe as CORBA
proxies generated by C++/C/Java/Lisp/Python IDL compiler are normal
classes which know what methods they have...

Thanks a lot! After reading your example I googled and found
unohelper.inspe ct, which provides all information. But I still need
instances, as 'dir(XSingleCom ponentFactory)' gives just ['__doc__',
'__module__', '__pyunointerfa ce__'], and
'unohelper.insp ect(XSingleComp onentFactory, sys.stdout)' gives
segmentation fault.
