[pygccxml-development] xxx_traits? container_traits questions generically

[Gustavo C. <gjc...@gm...>]

I am trying to use container_traits.find_container_traits():

http://www.language-binding.net/pygccxml/apidocs/pygccxml.declarations.container_traits-module.html

The return value of the function appears to be None or
pygccxml.declarations.container_traits.xxx_traits.  What's the deal with
this undocumented xxx_traits object?

In a related question, what is the easiest way to distinguish between
sequence (list, vector, set, ...) and associative (*map*) types?  And
finally, if I ever get a map_traits, documentation tells me of a
element_type attribute, but how do I get the key type (maps have keys and
values...).

Thanks in advance.
