Gtk.TreeModelFilter.prototype.clear_cache

function clear_cache():void {
    // Gjs wrapper for gtk_tree_model_filter_clear_cache()
}

This function should almost never be called. It clears the filter of any cached iterators that haven't been reffed with Gtk.TreeModel.prototype.ref_node. This might be useful if the child model being filtered is static (and doesn't change often) and there has been a lot of unreffed access to nodes. As a side effect of this function, all unreffed iters will be invalid.
