extract_template_args()

GaudiConfig2.semantics.extract_template_args

(

Return an iterator over the list of template arguments in a C++ type
string.

>>> list(extract_template_args(t))
['string', 'vector<int, allocator<int> >', 'allocator<v<i>, a<i>>']

getSemanticsFor()

GaudiConfig2.semantics.getSemanticsFor	(		cpp_type,

Return semantics for given type. If no type-specific semantics can be found
return DefaultSemantics. In strict mode, raise a TypeError instead.
