doctrine2 get info about updated field

HI, I want somehow to figure out which field was updated in the controller, I didn't found anything that might sound like what I'm trying to achieve in API doc for UnitOfWork. For example, I want to add on @PreUpdate code similar to this

/** @PreUpdate */ 
function updateAllIsDefaultFields(){
    //only if $this->isDefault propery for this entity is changed to 1 from its previous state, then update all other entities so they all have isDefault to 0

//else, means that this field is not changed, don't do anything

    }

Or this must be done from the controller on every action?

I know that I can do it every time just if $this->isDefault is set to 1, but I would like to avoid it for performance and I might find it useful for some other scenarios as well. Thanks in advance

You will have to write an Event Subscriber. Probably using an onFlush event, you can retrieve an Entities ChangeSet from the UnitOfWork to determine if a certain field has been updated and then do what ever you want.
