-
-// scoped_ptr mimics a built-in pointer except that it guarantees deletion
-// of the object pointed to, either on destruction of the scoped_ptr or via
-// an explicit reset(). scoped_ptr is a simple solution for simple needs;
-// use shared_ptr or std::auto_ptr if your needs are more complex.
-
-// *** NOTE ***
-// If your scoped_ptr is a class member of class FOO pointing to a
-// forward declared type BAR (as shown below), then you MUST use a non-inlined
-// version of the destructor. The destructor of a scoped_ptr (called from
-// FOO's destructor) must have a complete definition of BAR in order to
-// destroy it. Example:
-//
-// -- foo.h --
-// class BAR;
-//
-// class FOO {
-// public:
-// FOO();
-// ~FOO(); // Required for sources that instantiate class FOO to compile!
-//
-// private:
-// scoped_ptr<BAR> bar_;
-// };
-//
-// -- foo.cc --
-// #include "foo.h"
-// FOO::~FOO() {} // Empty, but must be non-inlined to FOO's class definition.
-
-// scoped_ptr_malloc added by Google
-// When one of these goes out of scope, instead of doing a delete or
-// delete[], it calls free(). scoped_ptr_malloc<char> is likely to see
-// much more use than any other specializations.
-
-// release() added by Google
-// Use this to conditionally transfer ownership of a heap-allocated object
-// to the caller, usually on method success.
