namespace love

 * Superclass for all object that should be able to  cross the Lua/C border
 * (this pertains to most objects).
 * This class is an alternative to using smart pointers; it contains retain/release
 * methods, and will delete itself with the reference count hits zero. The wrapper
 * code assumes that all userdata inherits from this class.
class Object

	 * Constructor. Sets reference count to one.

	 * Destructor.
	virtual ~Object() = 0;

	 * Gets the reference count of this Object.
	 * @returns The reference count.
	int getReferenceCount() const;

	 * Retains the Object, i.e. increases the
	 * reference count by one.
	void retain();

	 * Releases one reference to the Object, i.e. decrements the
	 * reference count by one, and potentially deletes the Object
	 * if there are no more references.
	void release();


	// The reference count.
	int count;
