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.
