Cursor.setCacheMode介绍

[英]Sets the CacheMode default used for subsequent operations performed using this cursor. This method may be used to override the defaults specified using DatabaseConfig#setCacheMode and EnvironmentConfig#setCacheMode. Note that the default is always overridden by a non-null cache mode that is specified via ReadOptions or WriteOptions.
[中]设置用于使用此光标执行的后续操作的CacheMode默认值。此方法可用于覆盖使用DatabaseConfig#setCacheMode和EnvironmentConfig#setCacheMode指定的默认值。请注意，默认值始终由通过ReadOptions或WriteOptions指定的非空缓存模式覆盖。
