Searching the tree (similar to filter)

Hi, what is the best way to search for a node in the tree by some function (just like filter), but without any side effects (ex: filter is hiding the nodes). I just want to receive the list of nodes. I need this to programatically focus a node on the tree that his name contains something (I will focus the first node of the filtered list)

The true flag in the filterNodes is still hiding the ones that did not match the comparison. I just want to list back. I can of course iterate the tree on my own recursively but maybe there is already an easier way 😃

Edit: Searching like this seems to be okay:

let arr = [] 
let iter = (node) => {
      arr.push(...node.filter(child => {
        if (child.children)
          iter(child.children);
        return child.data.key == this.displayedNode.value.patternKey
      }));
    }
 iter(this.tree.treeModel.roots);
console.log(arr)

Currently there’s no built-in iteration over treeNodes, but I can add it.

Something like this maybe:

treeModel.forEachNode((node) => ...)

?

Hi,

can you please post a full example about using filter?
