Macro to generate the required bundle activator functions for C++. This can be used to more type safe bundle activator entries.

The macro will create the following bundle activator C functions:

• bundleActivator_create, which will create the required C++ object (bundle context and dependency manager) and create the C++ bundle activator class (RAII)
• bundleActivator_start function, which for C++ will do nothing.
• bundleActivator_stop function, which will trigger the destruction of the C++ BundleActivator and ensure that there is no dangling usage of the bundle context and/or dependency manager.
• bundleActivator_destroy function, which for C++ will do nothing.

The destruction of the C++ BundleActivator is triggered in the bundleActivator_stop instead of bundleActivator_destroy to ensure that the C++ dependency manager does is cleanup before the C dependency manager. This is needed, because the C dependency manager is not aware of "above lying" C++ objects.

Parameters

type	The activator type (e.g. 'ShellActivator'). A type which should have a constructor with a single argument of std::shared_ptr<celix::BundleContext> or std::shared_ptr<DependencyManager>.
