lcrtrel Namespace Reference

The namespace lcrtrel holds classes and functions for runtime extensions and relations see LCRTRelations for more detailed documentation. More...

Classes
struct	LCExtension
	Simple Extension - pointer to an object of type T. More...
class	LCOwnedExtension
	Simple Extension - pointer to an object of type T where the ownership is taken over by the object holding the extension, i.e. More...
class	LCExtensionVector
	Extension vector holding pointers to objects of type T - no ownership of the objects is taken. More...
class	LCOwnedExtensionVector
	Extension vector holding pointers to objects of type T - ownership of the objects is taken, i.e. More...
class	LCExtensionList
	Extension list holding pointers to objects of type T - no ownership of the objects is taken. More...
class	LCOwnedExtensionList
	Extension list holding pointers to objects of type T - ownership of the objects is taken, i.e. More...
struct	LC1To1Relation
	One to one relation between two objects of type From and To. More...
struct	LC1ToNRelation
	One to many relation between one object of type From to many objects of type To. More...
struct	LCNToNRelation
	Many to many relation between objects of type From to objects of type To. More...
struct	LCIntExtension
	Special Extension that allows to write int extensions directly (not through a pointer !). More...
struct	LCFloatExtension
class	LCRTRelations
	Base class that provides run time (user) extensions and relation between objects. More...
Functions
template<class R >
void	set_relation (typename R::from::obj_ptr f, typename R::to::obj_ptr t)
	Set the 1-to-1 relation between two objects - prexisting inconsistent relations involving the two objects are deleted to enforce a consistent set of from-to relations.
template<class R >
void	unset_relation (typename R::from::obj_ptr f)
	Unset the 1-to-1 relation from f.
template<class R >
void	add_relation (typename R::from::obj_ptr f, typename R::to::obj_ptr t)
	Add a link from f to t to an N-to-N relation ship.
template<class R >
void	remove_relation (typename R::from::obj_ptr f, typename R::to::obj_ptr t)
	Remove the link from from f to t from the N-to-N relation ship.
template<class R >
void	remove_relations (typename R::from::obj_ptr f)
	Removes all relations from the given object.
template<class R >
void	merge_relations (typename R::from::obj_ptr f1, typename R::from::obj_ptr f2)
	Merge the relations from f2 to f1 - after this call f1 will hold all the relations and f2 will be empty.

template<class R >

void lcrtrel::set_relation	(	typename R::from::obj_ptr	f,
		typename R::to::obj_ptr	t
	)			[inline]

Set the 1-to-1 relation between two objects - prexisting inconsistent relations involving the two objects are deleted to enforce a consistent set of from-to relations.
