fcppt::unique_ptr< Type, Deleter > Class Template Reference

Detailed Description

template<typename Type, typename Deleter>
class fcppt::unique_ptr< Type, Deleter >

A simpler unique_ptr that shouldn't be used as a null pointer.

std::unique_ptr can easily be used as a null pointer because it has a default constructor and also a reset function. Null pointers should always be handled by optional references instead (see fcppt.optional). While it is not possible to completely forbid unique pointers that are null, this class makes it harder to do so. Unique pointers that have been moved from are still null because a unique pointer must track its ownership status. Make sure not to access such pointers.

Releases ownerhsip.

This can be used to move the pointer to another class that takes over ownership. Use this with extreme caution.
