Description copied from class: RangeCursor

Closes the given cursor.

Overrides:

closeCursor in class RangeCursor

Throws:

checkRecordNumber

protected boolean checkRecordNumber()

Description copied from class: RangeCursor

If the database is a RECNO or QUEUE database, we know its keys are record numbers. We treat a non-positive record number as out of bounds, that is, we return NOTFOUND rather than throwing IllegalArgumentException as would happen if we passed a non-positive record number into the DB cursor. This behavior is required by the collections interface.

Overrides:

checkRecordNumber in class RangeCursor
