param annotation at goog.ui.Container.addChild #510

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
goog.ui.Container.addChild(child, opt_renderer) requires child parameter to be 
goog.ui.Component (annotation @param {goog.ui.Component} child The new child 
control.)
It says that child should be control. And also first line of this method 
asserts that:
goog.asserts.assertInstanceof(child, goog.ui.Control,'The child of a container 
must be a control');

So please change the annotation to this:
@param {goog.ui.Control} child The new child control.
