Examples of StoredList

com.sleepycat.bdb.collection.StoredList

A List view of a {@link DataStore} or {@link DataIndex}.

For all stored lists the keys of the underlying DataStore or DataIndex must have record number format, and therefore the store or index must be a RECNO, RECNO-RENUMBER, QUEUE, or BTREE-RECNUM database. Only RECNO-RENUMBER allows true list behavior where record numbers are renumbered following the position of an element that is added or removed. For the other access methods (RECNO, QUEUE, and BTREE-RECNUM), stored Lists are most useful as read-only collections where record numbers are not required to be sequential.

In addition to the standard List methods, this class provides the following methods for stored lists only. Note that the use of these methods is not compatible with the standard Java collections interface.
