public function getPropertyPath()
Returns
string
The property path indicates how the validator reached the invalid value from the root element. If the root
element is a <tt>Person</tt> instance with a property
"address" that contains an <tt>Address</tt> instance
with an invalid property "street", the generated property
path is "address.street". Property access is denoted by
dots, while array access is denoted by square brackets,
for example "addresses[1].street".
