seastar::weak_ptr< T > Class Template Reference

Detailed Description

template<typename T>
class seastar::weak_ptr< T >

A non-owning reference to an object.

weak_ptr allows one to keep a non-owning reference to an object. When the object is destroyed, it notifies all weak_ptr instances pointing to it. A weak_ptr instance pointing to a destroyed object is equivalent to a nullptr.

The referenced object must inherit from weakly_referencable. weak_ptr instances can only be obtained by calling weak_from_this() on the to-be-referenced object.
