function declareProjection ##

inline const PROJ & declareProjection(
    const PROJ & proj,
    const std::string & name
)

Register a contained projection.

Todo: Add SFINAE to require that PROJ inherit from Projection

The type of the argument is used to instantiate a new projection internally: this new object is applied to events rather than the argument object. Hence you are advised to only use locally-scoped Projection objects in your Projection and Analysis constructors, and to avoid polymorphism (e.g. handling ConcreteProjection via a pointer or reference to type Projection) since this will screw up the internal type management.

template <typename PROJ >
inline const PROJ & declare(
    const PROJ & proj,
    const std::string & name
)
