Remarks
These enumerators are used to specify the type of SelectionSets returned by ITable::Select, IFeatureClass::Select, IFeatureLayer::Select.
Depending on the number of rows or features selected this option lets you define if the SelectionSet will store only IDs or a set of instantiated rows in memory.
esriSelectionTypeIDSetThe selection is always based on a persistent set of OIDs (e.g. logfiles for ArcSDE)
esriSelectionTypeSnapshotThe selection is always based on a set of in-memory rows (e.g. no logfile just in-memory IRow(s))
esriSelectionTypeHybridThe selection itself decides how to manage its representation (e.g. it may morph between IDSet and Snapshot)
