包路径：com.sleepycat.je.Cursor
类名称：Cursor
方法名：getLast

Cursor.getLast介绍

[英]Moves the cursor to the last key/data pair of the database, and returns that pair. If the last key has duplicate values, the last data item in the set of duplicates is returned.

Calling this method is equivalent to calling #get(DatabaseEntry,DatabaseEntry,Get,ReadOptions) with Get#LAST.
[中]将光标移动到数据库的最后一个键/数据对，并返回该对。如果最后一个键具有重复值，则返回重复集合中的最后一个数据项。
调用此方法相当于使用get#LAST调用#get（DatabaseEntry，DatabaseEntry，get，ReadOptions）。
