Public Member Functions
	GmLuaSpatialIndex (GmSpatialIndex *si, bool newIndex, const GmLogCategory &logger)
	Constructor. Receives the spatial index to be wrapped. If newIndex is true, the proxy takes ownership of the supplied index.

virtual	~GmLuaSpatialIndex ()
	Destructor.

virtual const char *	typeName () const
	Returns the object type as will be stored in the object metatable.

virtual void	fillMetatable (lua_State *L, int index)
	Prepares the object metatable for calling methods.

virtual void *	getClassMetatableID ()
	Returns an unique identifier to identify an user object as a GmLuaSpatialIndex object.

GmSpatialIndex *	index () const
	Returns the wrapped spatial index.

Public Member Functions inherited from GmLuaObject
virtual	~GmLuaObject ()
	Destrutor.

virtual void	populateMetatable (lua_State *L, int index)
	Fills the object metatable to allow for the proxy to export its methods.

QVariant	ptrToVariant ()
	Constructs a QVariant storing a POINTER to the current object.

void	ref ()
	Increments the object reference count. Use with care.

Protected Attributes
GmSpatialIndex *	_si
	The spatial index 'wrapped' by this proxy object.

bool	_newIndex
	Is thos a new spatial index whose ownership belongs to the proxy?

Protected Attributes inherited from GmLuaObject
const GmLogCategory &	_logger
	A logger used by the proxy when needed.

QAtomicInteger< int >	_refCount
	Lua objects are reference counted to enable sharing them among different states. This is needed to allow for passing objects as parameters in a parallel call. The garbage collection method releases memory only for the last reference.

Private Member Functions
int	id (lua_State *L)
	Returns the property set id.

int	hasCapability (lua_State *L)
	Returns true or false indicating whether the index supports the requested capability (a string) or not.

int	closestNode (lua_State *L)
	The closestNode (old mm.getClosestNode() process) implementation.

int	closestNodes (lua_State *L)
	The closestNodes (old mm.getClosestNodes() process) implementation.

int	closestNodesInRadius (lua_State *L)
	The closestNodesInRadius (old mm.getClosestNodes() process) implementation.

int	containingCell (lua_State *L)
	The containingCell (old mm.getContainingCell() process) implementation.

int	closestGaussPoint (lua_State *L)
	The closestGaussPoint (old mm.getClosestGaussPoint() process) implementation.

int	closestGaussPoints (lua_State *L)
	The closestGaussPoints (old mm.getClosestGaussPoints() process) implementation.

int	closestGaussPointsInRadius (lua_State *L)
	The closestGaussPointsInRadius (old mm.getClosestGaussPoints() process) implementation.

Additional Inherited Members
Protected Member Functions inherited from GmLuaObject
	GmLuaObject (const GmLogCategory &logger)
	Construtor protegido. Somente classes derivadas devem ser instanciadas.

virtual QString	toString () const
	Default method used by the __tostring metamethod to capture the result of tostring() over an object.
