包路径：org.apache.brooklyn.core.entity.Entities
类名称：Entities
方法名：manage

Entities.manage介绍

[英]Brings this entity under management only if its ancestor is managed.

Returns true if successful, otherwise returns false in the expectation that the ancestor will become managed, or throws exception if it has no parent or a non-application root.
[中]仅当其祖先被管理时，才将此实体置于管理之下。
如果成功，则返回true，否则返回false，预期祖先将被管理，或者如果没有父级或非应用程序根，则抛出异常。
