Henri Yandell commented on LANG-790:
------------------------------------

Seems like a BeanUtils function.

> Adding a method for null safe navigation of objects will be very helpful. for example
a method like
> ObjectUtils.getValue(Object obj, String "path", String defaultValue); 
> ex :ObjectUtils.getValue(myObject, "x.y.z", "default");
> it will navigate in the myObject like myObject.getX().getY().getZ(), if any thing in
the path is null (x,y or z), it will return the default value.
> It will be really useful, it is like null safe navigation in groovy.
