Smart Pointers and Stuff

[Enigma]

This is just a small collection of functions and classes that I have written and may be of use to someone. The name of the header file could use a better name, and if your compiler doesn't support partial template specialization then you are out of luck.


Noncopyable class

This class is meant to be subclassed by classes that shouldn't be copyable. Its copy constructor and assignment operator are both declared private.

Type Traits

I have a bunch of type traits classes that I have been writing on and off for some time, mainly as educational exercises, but only a small subset of what I have written is included here.

remove_const

Removes top-level const qualifiers. Actually it just typedefs the type without the const qualifier. For instance, bzf::remove_const<const int>::Type will be of type int.

remove_volatile

Removes the volatile qualifier from a type.

remove_cv

Removes const and volatile qualifiers.

is_bz_container

This is a type trait to find out if an unknown type is one of the bzfs containers. Usage: bzf::is_bz_container<T>::value. If T is a bzfs container, value will be true. The remove_const and remove_volatile classes were included because this class requires them.

bz_delete()

This function will properly delete anything, except arrays. If the type is one of the bzfs containers, it will call the proper delete functions, such as bz_deleteIntList(). If it is any other type, the function will just call delete.

sendMessage()

These functions are just for convenience.

local_ptr

This is a simple, noncopyable smart pointer class. I wrote it as an academic exercise while reading Modern C++ Design and C++ Templates: The Complete Guide, and it is basically the same as std::auto_ptr, except it does not transfer ownernship. The local_ptr class also uses the bz_delete() function to properly delete bzfs containers.
