Examples of com.sun.sgs.service.store.db.DbCursor.findNext()

com.sun.sgs.service.store.db.DbCursor.findNext()
Searches for the next key in the database. If the cursor has no current key, then searches for the first key. If the result is {@code true}, then sets the current key and value to the key found and its associated value. @return {@code true} if the next key was found, else {@code false} @throws TransactionAbortedException if the transaction should beaborted due to timeout or conflict @throws DbDatabaseException if an unexpected database problem occurs
