Что делает эта функция?

function
clearMap(visible)
{
	for ( var id = 0; id < b_adverts.length; id++)
	{
		if (null != b_adverts[id]) b_adverts[id].setVisible (visible);
		if (null != e_adverts[id]) e_adverts[id].setVisible (visible);
	}
	for (var ovr = 0; ovr < i_adverts.length; ovr++) i_adverts[ovr].close();
	
	if (visible)
	{
		El('adverts_line').style.visibility = 'visible';
	}
	else
	{
		El('adverts_line').style.visibility = 'hidden';
	}
}
