public class DuplicateKey extends DatabaseException
ObjectIndex throws a DuplicateKey when a key being added to the
index is identical to a key already stored there. Each concrete index class
determines the circumstances under which this exception is thrown. For example,
a BTreeIndex will throw DuplicateKey
when a call to the insertKey method finds an existing key that
matches the insertion key; however, the BTreeIndex.writeKey method
does not throw an exception for a duplicate key, instead replacing the record
position associated with the extant key.
