Breadth-, Depth-, Preorder-Search in JavaFX Tree

Question

Java's DefaultMutableTreeNode had methods for tree iteration:

• breadthFirstEnumeration();
• depthFirstEnumeration();
• preorderEnumeration();
• postorderEnumeration();

Is there something similar in JavaFX?

Answer 1

No, there are no corresponding built-in APIs in JavaFX 8. You can create your own. There are some examples for depth first search here:

• TreeView - How to count all children (including collapsed)

Implementing breadth first search is similar to the linked examples, you just use a Queue data structure instead of a stack.

Feature requests to build such functionality into the JavaFX tree structure can be filed at: https://javafx-jira.kenai.com. The OpenJFX development team might accept a patch which implements these features.
