包路径：com.mxgraph.view.mxGraph
类名称：mxGraph
方法名：isCellVisible

mxGraph.isCellVisible介绍

[英]Returns true if the given cell is visible in this graph. This implementation uses . Subclassers can override this to implement specific visibility for cells in only one graph, that is, without affecting the visible state of the cell. When using dynamic filter expressions for cell visibility, then the graph should be revalidated after the filter expression has changed.
[中]如果给定单元格在此图中可见，则返回true。此实现使用。子类可以覆盖该属性，以便只在一个图形中实现单元格的特定可见性，也就是说，不影响单元格的可见状态。当为单元格可见性使用动态过滤器表达式时，应在过滤器表达式更改后重新验证图形。
