This interface must be implemented by the plug-in dataset helper class of a plug-in data source.

In the following, the term 'class' is used as a general terming meaning 'feature class or table'.  Some of the methods on this interface have a classIndex parameter, because these methods can have different results for different classes within a feature dataset.  If the dataset is not a feature dataset, the parameter will always have a value of 0 and may be ignored by the implementation.  If the dataset is a feature dataset, the value will be the index of a feature class in the dataset (0 <= classIndex < result of get_ClassCount).
