Constrain the number of in-/outgoing edges from/to vertex?

Currently I have a class A extends V and a class B extends E.
Now I would like to constrain the number of B edges that go out of A to say 2.
Is this possible and if it is how can I accomplish this?
I could not find anything useful about this, only about LINK properties but I would like to use edges.

You can try to use hooks (equivalent to triggers in RDBMS) to control the CRUD operations on your schema: http://www.orientechnologies.com/docs/last/Hook.html.
