is it necessary to take case of “delete item” if the item is create by XXX::type_id::create instead of new?

[Jerome]

A *item = A::type_id::create("item", this);

I am curious about the difference from systemverilog? should I delete item by myself,  or will uvm systemc lib totally take over it?

[Jerome]

"take care" , sorry for the typo

You need to take care yourself as the factory just calls new and returns a raw pointer. You should use a std::unique_ptr to hold the raw pointer:

#include <memory>

std::unique_ptr<A> a{A::type_id::create("item", this)}; 

or if you have to keep declaration and initialization separate:
 

#include <memory>

std::unique_ptr<A> a;
a.reset(A::type_id::create("item", this)); 

This way C++ takes care of destruction properly

your reply is very helpful.
