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

com.sun.sgs.service.store.db.DbCursor.findFirst()
Searches for the first key in the database. If the result is {@code true}, then sets the current key and value to the first key and its associated value. @return {@code true} if the first 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
