IODIdGenerator Class

class IODIdGenerator

This interface is used by CODComponent to obtain unique IDs. It is implemented by CODModel so that component IDs are unique within a given diagram model. The CODComponent::GetIdGenerator method enables individual components to get a pointer to an IODIdGenerator interface and obtain a unique ID. The current implementation of CODComponent::GetIdGenerator will return a pointer to the diagram model's IODIdGenerator interface.

To implement your own ID generation scheme, override CODModel::CreateUniqueID.
