`sap.m.Select.getSelectedIndex` has no declaration

[sap-sebelao]

Example:

import Select from "sap/m/Select";

let select = new Select();
select.getSelectedIndex(); // TS: Property 'getSelectedIndex' does not exist on type 'Select'.

I looked into the SDK and it does not seem to be part of the documentation either - which would point to the fact that this is not a public method, however I looked directly into the source of truth - the sap.m.Select code itself, and there is no @private tag:

/**
 * Retrieves the index of the selected item from the aggregation named <code>items</code>.
 *
 * @returns {int} An integer specifying the selected index, or -1 if no item is selected.
 * @since 1.26.0
*/
Select.prototype.getSelectedIndex = function() {
    var oSelectedItem = this.getSelectedItem();
    return oSelectedItem ? this.indexOfItem(this.getSelectedItem()) : -1;
};

So this seems strange, it's JSDoc does not seem to imply that this method is private, but it does not show up in SDK and the generated .d.ts anyway.

In general, the default visibility (when not specified) in SAPUI5 code is @private, not @public. This is to avoid that a developer accidentally makes a new method public (and thereby subject to our compatibility rules).

In the special case of sap.m.Select#getSelectedIndex and its neighbours, I wonder however, if the current status is intentional.

Would you mind to open an issue in SAP/openui5, asking the same?

Or, @kineticjs and @jdichev can you please take a look or forward accordingly?

Hello @sap-sebelao ,

The method in question is not related to a public property and it's meant to be used internally, we marked it as private.
