* This method validates the passed objects against all constraints defined
|

* at class level. It furthermore triggers the validation of each of the
|
||
|
|
* class' properties against the constraints for that property.
|
||
|
|
*
|
||
|
|
* If the selected traversal strategy allows traversal, the object is
|
||
|
|
* iterated and each nested object is validated against its own constraints.
|

|

* metadata.
|

*

|
|
* If the passed groups contain the group "Default", the validator will
|
||
|
|
* check whether the "Default" group has been replaced by a group sequence
|
||
|
|
* in the class metadata. If this is the case, the group sequence is
