Data Structures
class	CountedRefPtr< PtrType, Nondestructive, NeverNull, CountType >
	This class implements a smart pointer which handles pointer-style access to a reference-counted structure and destructing the latter after use. More...
class	RefCounter
	This class implements implements a refernce counter which we can use as a public base of objects managed by @CountedRefPtr. More...
class	CountedRefIndirectPtr< PtrType >
class	CountedRefWeakPtr< PtrType >
class	LeftvHelper
	This class implements some recurrent code sniplets to be used with leftv and idhdl.implements a refernce counter which we can use. More...
class	LeftvShallow
	Ths class wraps leftv by taking into acount memory allocation, destruction as well as shallowly copying of a given leftv, i.e. More...
class	LeftvDeep
	This class wraps leftv by taking into acount memory allocation, destruction as well as deeply copying of a given leftv, i.e. More...
struct	LeftvDeep::copy_tag
	Construct even deeper copy: Skip identifier (if any) and take care of the data on our own. More...
