class nub::ref_counted

Detailed Description

nub::ref_counts manages strong+weak reference counts for nub::ref_counted objects. Its main purpose is to allow weak ref-counting; a client who wants to do weak ref-counting can get a hold of the nub::ref_counted object's nub::ref_counts, and then check whether is_owner_alive() to know whether the nub::ref_counted object is still valid. This technique is implemented by nub::soft_ref. The nub::ref_counts object will delete itself when both its strong and weak counts go to 0.
