I guess this what I was looking for

well, getNode(path).isCollection() will throw a NullPointerException 
when the node does not exist, hence I would like to test it first.
Of course one could do something like

getNode(path) !=  null && getNode(path).isCollection()

but I think

existsNode(path) && getNode(path).isCollection()

is nicer ;-)
