Returns the numeric identifier (ID) of the wrapped C++ class instance.
Different Python OStream instances may reference the same underlying C++ class instance. The commonly used Python expression a is not b
thus cannot tell reliably whether the two OStream instances a and b reference different C++ objects. The numeric identifier returned by this method allows to correctly implement such an identity test via the simple expression a.getObjectID() != b.getObjectID()
.
- Returns
- The numeric ID of the internally referenced C++ class instance.
