包路径：org.apache.accumulo.core.iterators.YieldCallback
类名称：YieldCallback
方法名：getPositionAndReset

YieldCallback.getPositionAndReset介绍

[英]Called by the client to get the yield position used as the start key (non-inclusive) of the range in a subsequent seek call when the iterator is rebuilt. This will also reset the state returned by hasYielded.
[中]由客户端调用，以在重建迭代器时，在后续的seek调用中获取用作范围的开始键（非包含）的屈服位置。这也将重置HasGender返回的状态。
