Version.getPredecessors介绍

[英]In both simple and full versioning repositories, this method returns the predecessor versions of this version. This corresponds to returning all the nt:version nodes whose jcr:successors property includes a reference to the nt:version node that represents this version.
[中]在简单版本控制存储库和完整版本控制存储库中，此方法都会返回此版本的先前版本。这相当于返回所有nt:version节点，这些节点的jcr:successors属性包含对表示此版本的nt:version节点的引用。
