|
| -// Example usage (scoped_ptr):
|
| -// {

|

|
| -// foo.reset(new Foo("wee3")); // Foo("wee2") was destroyed.
|
| -// foo->Method(); // Foo::Method() called.
|
| -// foo.get()->Method(); // Foo::Method() called.
|

|

|
| -// foo.reset(); // Foo("wee4") destroyed, foo no longer
|
| -// // manages a pointer.
|
| -// } // foo wasn't managing a pointer, so nothing was destroyed.

|
| -// Example usage (scoped_array):
|
