Member Function Documentation

void c10::StorageImpl::release_resources ( )

inlineoverridevirtual

This is called when refcount reaches zero.

You can override this to release expensive resources. There might still be weak references, so your object might not get destructed yet, but you can assume the object isn't used anymore, i.e. no more calls to methods or accesses to members (we just can't destruct it yet because we need the weakcount accessible).

Even if there are no weak references (i.e. your class is about to be destructed), this function is guaranteed to be called first. However, if you use your class for an object on the stack that is destructed by the scope (i.e. without intrusive_ptr), this function will not be called.

Reimplemented from c10::intrusive_ptr_target.
