LinkingIterator (Apache Accumulo Core 2.0.0 API)

java.lang.Object
- org.apache.accumulo.core.metadata.schema.LinkingIterator

All Implemented Interfaces:

Iterator<TabletMetadata>
```
public class LinkingIterator
extends Object
implements Iterator<TabletMetadata>
```
Tablets for a table in the metadata table should form a linked list. This iterator detects when tablets do not form a linked list and backs up when this happens.
The purpose of this is to hide inconsistencies caused by splits and detect anomalies in the metadata table.
If a tablet that was returned by this iterator is subsequently deleted from the metadata table, then this iterator will throw a TabletDeletedException. This could occur when a table is merged.
