Re: [Orbit-python-list] TypeCode and Anys?

[Gustavo C. <gj...@in...>]

  I was having the same doubts as you some time ago. In fact I still do!
But I have discovered that CORBA::any's work anyway if you don't care
about corba type codes. Say you have this:
	result =3D some_corba_object.some_method_that_returns_any(foo,bar)
Then, you can get the value as:
	value =3D result.value
Then, value is a standard python object, and you can use python's type
system to differentiate types. For example, if the CORBA::any is of type
TC_CORBA_string, you the following expression is true:
	type(value) is StringType

  Don't ask me how to create CORBA::any from python, though, as I
haven't tried that yet.
