Detailed Description

template<typename EnumType>
class PDGT_TypeInstance< EnumType >

The base class for all instances created using a PDGT_RegisteredType. The Class argument to the registered type should derive from this class.

This class provides basic functionality common to all instances, such as: 

 Providing the ability to look up a back reference to the type object
 Tracking whether or not the instance is currently being reloaded.

This class also defines the reloadInstance virtual method, which is called when the instance should reload itself. Typically, the instance will need to implement a custom method that calls type()->reloadInstance(...) with itself as an argument, and the various other construction arguments needed in order to properly re-initialize the underyling object.

For example, nodes based on Python classes needed to reconstruct their underyling Python instance, which requires passing in the PDG_Node as a construction argument. PDG_NodeCallback, which is a subclass of this class, defines a custom reloadInstance method that makes the correct call into its PDG_NodeCallbackType::reloadInstance method with the PDG_Node as an argument.
