[TYPO3-mvc] RFC: ##12358 Add getConstraint() to the queryinterface

It is, just do $query->getConstraint(). It's implemented inside
Tx_Extbase_Persistence_Query.

You are right that getConstraint() is NOT inside the interface, but this
is done on purpose: The reason for this is that not all query
implementations might be able to give back a constraint if they are
asked for it; and that's why it is not in the interface.

Hope this helps :-)

Greets,
