bug(aria/tree): missing documented methods on Tree<V> class

[mvukic]

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

I don't believe it worked in version

Description

It seems that the methods mentioned at Aria Tree documentation do not actually exist on the Tree directive class.

Methods are:

• expandAll()
• collapseAll()
• selectAll()
• clearSelection()

After additional investigation of the distributed types I found that they do exist on type Tree<T extends TreeItem<V, T>, V> in _tree-chunk.d.ts but I am not sure how this type relates to Tree<V>.

Reproduction

Try to call any of the mentioned methods on Tree instance and they will be undefined.

Expected Behavior

Mentioned methods to exist on the Tree class and do what their names are indicating.

Actual Behavior

Can't find mentioned methods on the Tree class.

Environment

• Angular: 22.1-next.2
• CDK/Material: Aria
• Browser(s): Chrome but should not make a difference
• Operating System (e.g. Windows, macOS, Ubuntu): Windows 11 but should not make a difference

Thanks for raising this up! I can confirm there are some mismatches between the documentation and the actual implementation. Those are APIs been considered but ended up abandoned because there are alternative ways of handling those via individual expanded state and value input.

We will clean up the documentation, but meanwhile if you think providing those methods can be beneficial, let us know :)
