Specified by:

validate in interface EntityValidation<E extends SimpleEntity>

getEntityManagerHandler

protected EntityManagerHandler getEntityManagerHandler()

Returns an EntityManagerHandler which can be used by validations which need database access

isValid

protected abstract boolean isValid(Object object,
                                   Object property,
                                   E entity)

Should be implemented to return whether the value is valid. If the value is valid, the validate(Object, Object, SimpleEntity) method will return null. Otherwise, will return the ValidationError received on the constructor (or a general validation error if none was passed)
