Re: [cdt-dev] Getting methods/fields from CPPClassTemplate

[Andrew Niefer <aniefer@xxxxxxxxxx>]

The first thing to note is that your
are mixing 2 different models here.  The
cdt.core.model classes are unrelated
to the cdt.core.dom.ast classes.
 It is incorrect to be mixing the two models.

CPPClassTemplate actually extends CPPTemplateDefinition,
not CPPClassType, the get* methods that return null do so simply because
I never had time to implement them.
Assuming I'm not forgetting something,
you can probably use the same kind of the implementation as CPPClassType.

There is still work to be done here.
 Note that these methods are also unimplemented for the instantiations
and specializations of class templates (CPPClassInstance, CPPClassSpecialization).
 However, you can't just use the CPPClassType implementations here
since the members need to be instantiated or specialized as appropriate.
 CPPClassInstance should likely implement ICPPInternalClassType, proper
implementations of getConstructors and getConversionOperators would improve
the resolution of template bindings in arbitrary code.
