Since the current smart_ptr (policy_ptr) class at boost vault is on hold, I like to propose adding the following smart_ptr class to the boost library:
Could you eliminate the tabs and reformat to something like 75 or 80 columns to ease reading. An example is in http://boost-consulting.com/vault/Memory. Also, boost convention is .hpp (or hxx or something like that) extension instead of .h.
IMHO, the above class has more functional features, than the class in
I notice policy_ptr has a weak_ptr class. Does axter smart_ptr has something similar to handle cycles in pointer graph?
the boost vault, and the class is ready for use.
I've compiled and run the policy_ptr tests with g++. [snip]
In my performance test, the shared and COW policies along with reference-link policy, are able to out perform the boost::shared_ptr.
Could this be due to shared_ptr having two refcounts and smart_ptr having just one? [snip] Of course you mean weak_ptr? Does this support mean cycles can occur if they're broken by the smart_ptr's version (if any) of boost::weak_ptr?
