db.collection.isCapped()

db.collection.isCapped()

Important

This page documents a mongosh method. This is not the documentation for database commands or language-specific drivers, such as Node.js.

For the database command, see the capped field returned by the collStats command.

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

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

~~Returns:~~返回值：	~~Returns `true` if the collection is a capped collection, otherwise returns `false`.~~如果集合是封顶集合，则返回`true`，否则返回`false`。
