The OdRxObject class provides the ability to copy Rx instances:

• Copying the content of an instance — Copies whole content or part of the content from one instance into another instance, which gives the ability to initialize an instance using other instance as a pattern. Use the CopyFrom() method, which requires the raw pointer to the source instance as an argument, does not return a value, and copies its content.
• Cloning an instance — Creates a new instance that is the duplicate of an existing instance. The duplicate will have the same content, but it will differ by reference counter data. Use the clone() method, which does not require arguments and returns the non-typified smart pointer to the duplicate. The clone() method calls the copyFrom() method to initialize the new instance.

The CopyFrom() and clone() methods are virtual and developers can redefine them in their own derived classes. The clone() method uses the copyFrom() virtual method that must be defined beforehand. When the copyFrom() method is undefined, the clone() method throws the exception: «This application has requested the Runtime to terminate it in an unusual way.»
