esriSelectionTypeSnapshot 2 Snapshot.
esriSelectionTypeHybrid 3 Snapshot if small, else an ID Set.

Product Availability

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.

esriSelectionTypeIDSet
The selection is always based on a persistent set of OIDs (e.g. logfiles for ArcSDE)

esriSelectionTypeSnapshot
The selection is always based on a set of in-memory rows (e.g. no logfile just in-memory IRow(s))

esriSelectionTypeHybrid
The selection itself decides how to manage its representation (e.g. it may morph between IDSet and Snapshot)
