包路径：org.apache.jackrabbit.oak.api.Root
类名称：Root

Root介绍

[英]A Root instance serves as a container for a Tree. It is obtained from a ContentSession, which governs accessibility and visibility of the Tree and its sub trees.

All root instances created by a content session become invalid after the content session is closed. Any method called on an invalid root instance will throw an InvalidStateException.

Tree instances may become non existing after a call to #refresh(), #rebase() or #commit(). Any write access to non existing Tree instances will cause an InvalidStateException.
[中]根实例充当树的容器。它是从ContentSession获取的，ContentSession控制树及其子树的可访问性和可见性。
内容会话关闭后，内容会话创建的所有根实例都将无效。对无效根实例调用的任何方法都将引发InvalidStateException。
调用#refresh（）、#rebase（）或#commit（）后，树实例可能不存在。对不存在的树实例的任何写访问都将导致InvalidStateException。
