the class TreePathEventHandler method handle.

@Override
public void handle(One<IPayload> payloadSink, Many<ChangeDescription> changeDescriptionSink, IEditingContext editingContext, Tree tree, ITreeInput treeInput) {
    IPayload payload = new TreePathSuccessPayload(treeInput.getId(), new TreePath(List.of(), 0));
    ChangeDescription changeDescription = new ChangeDescription(ChangeKind.NOTHING, treeInput.getRepresentationId(), treeInput);
    if (treeInput instanceof TreePathInput) {
        TreePathInput input = (TreePathInput) treeInput;
        Optional<ITreePathProvider> optionalPathProvider = this.treePathProviders.stream().filter(treePathProvider -> treePathProvider.canHandle(tree)).findFirst();
        if (optionalPathProvider.isPresent()) {
            IPayload resultPayload = optionalPathProvider.get().handle(editingContext, tree, input);
            if (resultPayload instanceof TreePathSuccessPayload) {
                payload = resultPayload;
            } else if (resultPayload instanceof ErrorPayload) {
                ErrorPayload errorPayload = (ErrorPayload) resultPayload;
                this.logger.warn(errorPayload.getMessage());
            }
        }
    }
    changeDescriptionSink.tryEmitNext(changeDescription);
    payloadSink.tryEmitValue(payload);
