-----------------------------------
Summary: C++ Object with mutiple services not working
Key: CELIX-386
URL: https://issues.apache.org/jira/browse/CELIX-386
Project: Celix
Issue Type: Bug
Reporter: Pepijn Noltes
Assignee: Pepijn Noltes
When providing multiple C++ services from a single object, the object first
needs to be cast before forwarding it as service to the C dep man.
This is because in most (all) implementations casting can result in pointers
with an offset.
For example If D is a class extending B1 and B2, depending on the inheritance
order, b1 or b1 will have a different pointer value.
D *d = new D();
B1 *b1 = static_cast<B1*>(d);
B2 *b2 = static_cast<B2*>(d);
