const PROJ& addProjection	(	const PROJ &	proj,
		const std::string &	name
	)		`[inline, protected, inherited]`

Register a contained 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.

virtual int compare ( const Projection & p ) const [protected, pure virtual, inherited]

This function is used to define a unique ordering between different Projection objects of the same class. If this is considered to be equivalent to the Projector object, p, in the argument the function should return 0. If this object should be ordered before p a negative value should be returned, otherwise a positive value should be returned. This function must never be called explicitly, but should only be called from the operator<(const Projection &). When implementing the function in concrete sub-classes, it is then guaranteed that the Projection object p in the argument is of the same class as the sub-class and can be safely dynamically casted to that class.

When implementing this function in a sub-class, the immediate base class version of the function should be called first. If the base class function returns a non-zero value, that value should be returned immediately. Only if zero is returned should this function check the member variables of the sub-class to determine whether this should be ordered before or after p, or if it is equivalent with p.
