CExpression* pExpr = new CExpression(); pExpr->AddRef(); // increment reference count
CExpression* pExpr = GetExpression(); pExpr->AddRef(); // increment reference count
CExpression* pExpr = CreateExpression();This example creates a new CExpression object, which initializes its reference count to 1. The AddRef method is typically called when another object or function requires a reference to the CExpression object. Based on the naming convention and usage of CExpression AddRef, it seems to be a part of a COM (Component Object Model) or a similar reference counting mechanism used for managing object reference in C++ code.
