mongosh Method

This is a mongosh method. This is not the documentation for Node.js or other programming language specific driver methods.

In most cases, mongosh methods work the same way as the legacy mongo shell methods. However, some legacy methods are unavailable in mongosh.

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.hasNext() returns true if the cursor returned by the db.collection.find() query can iterate further to return more documents.如果db.collection.find()查询返回的游标可以进一步迭代以返回更多文档，则cursor.hasNext()将返回true。
