The pre_scan_hook can be used to exclude classes or methods:

from pygccxml.declarations.class_declaration import class_t

def pre_scan_hook(module_parser,
                  pygccxml_definition,
                  global_annotations,
                  parameter_annotations):
    if isinstance(pygccxml_definition, class_t):
         if pygccxml_definition.name not in ["Class1", "Class2"]:
               global_annotations['ignore'] = None

Correct.  That is not possible.
