For the legacy mongo shell documentation, refer to the documentation for the corresponding MongoDB Server release:

• mongo shell v4.4
• mongo shell v4.2
• mongo shell v4.0

For MongoDB API drivers, refer to the language specific MongoDB driver documentation.

cursor.isClosed() returns true if the server has closed the cursor.如果服务器已关闭游标，cursor.isClosed()将返回true。

A closed cursor may still have documents remaining in the last received batch. 关闭的游标可能仍有最后接收到的批中的文档。Use cursor.isExhausted() or cursor.hasNext() to check if the cursor is fully exhausted.请使用cursor.isExhausted()或cursor.hasNext()检查游标是否已完全用尽。
