Openlayers 3 Max Extent

I want to restrict where the user can pan on the map, but I can't seem to find any resources that tell how to set the max extent of a map view in OpenLayers 3. I know there was a solution in OpenLayers 2. Is it possible in the new version?

Answer

This can simply be done by defining extent in the View object. eg

var view = new ol.View({
    ...
    extent: [minx,miny,maxx,maxy]
    ...
});
var map = new ol.Map({
    ...
    view: view,
    ...
});
