包路径：org.apache.jackrabbit.oak.api.Tree
类名称：Tree
方法名：orderBefore

Tree.orderBefore介绍

[英]Orders this Tree before the sibling tree with the given name. Calling this method for the first time on this Tree or any of its siblings will persist the current order of siblings and maintain it from this point on.
[中]在具有给定名称的兄弟树之前订购此树。首次在此树或其任何同级树上调用此方法将保持同级树的当前顺序，并从现在起保持该顺序。
