Enum IteratorType

Available ZoneTree Iterator Types.

public enum IteratorType

Name	Description
AutoRefresh	AutoRefresh iterator iterates through all available segments. It also includes newly inserted segments after any MoveMutableSegment. Newly inserted keys might not be included in the iteration if the iterator position advanced newly inserted positions.
NoRefresh	NoRefresh iterator iterates through all available segments. It does not include newly inserted segments after a new MoveMutableSegmentForward event. It can fetch newly inserted records to the current mutable segment. Newly inserted keys might not be included in the iteration if the iterator position advances newly inserted positions. Iterator can be manually refreshed.
ReadOnlyRegion	It is like Snapshot iterator but does not initiate MoveMutableSegmentForward. It fetches all available read-only segments. Since it does not contain the mutable segment the iterator is consistent across its lifetime. It does not see new writes to the database. You may manually call MoveMutableSegmentForward before creating the iterator, to ensure the current mutable segment's content is also included in the iteration.
Snapshot	Snapshot iterator initiates MoveMutableSegmentForward first when it is created. After that, it fetches all available read-only segments. Since it does not collect the mutable segment the iterator is consistent across its lifetime. It does not see new writes to the database.
