"Find classes that derive from css::uno::XAggregation, but which implement
queryInterface in violation of the protocol laid out in the documentation at
udkapi/com/sun/star/uno/XAggregation.idl (which implies that such a class either
doesn't actually make use of the deprecated XAggregation mechanism, which should
thus be removed from that class hierarchy, or that its implementation of
queryInterface needs to be fixed)." (compilerplugins/clang/unoaggregation.cxx)
The basesHaveOnlyPureQueryInterface check in
compilerplugins/clang/unoaggregation.cxx is "a crude approximation (but which
appears to work OK)" to filter out any queryInterface base implementations of
class hierarchies supporting XAggregation (i.e.,
cppu::OWeakAggObject::queryInterface). It only fails for the odd
ChartDocumentWrapper::queryInterface, which manually implements the XAggregation
functionality rather than (indirectly) deriving from OWeakAggObject. But
changing that manual implementation looks tricky, so leave that alone for now
and add a loplugin warning suppression there, and leave proper clean up for
later.
