Forward declaration of reference tracking interface.

The

RefTracker class defines an interface for reference counting, which can be specialized for different contexts, and which allows the type requiring tracking to clean up the resource as well.

Public Functions

auto add_reference () noexcept -> void

Adds a reference to the count.

auto release () noexcept -> bool

Decrements the referene count, returning true if the count is zero, and the resource can be released. If this returns true, then the resource should be destroyed through a call to destroy().

template<typename T, typename Deleter> auto destroy_resource (T *resource, Deleter &&deleter) noexcept -> void

Destroys the resource resource, using the deleter, which should have a signature of:

auto deleter = [] (auto* resource) -> void {
// delete the resource
}

Parameters

• resource: The resource to destroy.

• deleter: The deleter for the resource.

Template Parameters

• T: The type of the resource.

• Deleter: The type of the deleter.
