Detailed Description

template<typename T>
struct rack::WeakPtr< T >

A weak pointer to a subclass of WeakBase.

Weak pointers behave like raw pointers but can be accessed safely (returning nullptr) after the pointed object is deleted.

Example:

Foo* foo = new Foo;
WeakPtr<Foo> weakFoo = foo;
weakFoo.get(); // returns foo
delete foo;
weakFoo.get(); // returns nullptr

Not thread safe. In multithreaded environments, the object pointed to by the WeakPtr could be deleted at any time after obtaining its pointer from WeakPtr.
