[PropertyAccessor] Behavior of getValue

[nicolaspetitjean]

Hey !
I was reading that doc, and it says:

As you can see, the method will return null if the index does not exists.

I think the doc could mention that the behavior of PropertyAccessor::getValue can be configured, meaning if an index is missing, an exception can be thrown (see 27187).

$accessor = new PropertyAccessor(false, true, null);
