mxGraph.findTreeRoots介绍

[英]Returns all visible children in the given parent which do not have incoming edges. If the result is empty then the with the greatest difference between incoming and outgoing edges is returned. This takes into account edges that are being promoted to the given root due to invisible children or collapsed cells.
[中]返回给定父对象中没有传入边的所有可见子对象。如果结果为空，则返回传入边和传出边之间差异最大的。这将考虑由于不可见的子单元或折叠的单元而提升到给定根的边。
