Description copied from interface: IRepository.ReadAccessHandler
Provides a way to handle revisions that are to be sent to the client.

Specified by:
handleRevisionsBeforeSending in interface IRepository.ReadAccessHandler
Parameters:
session - The session that is going to send the revisions.
revisions - The revisions that are requested by the client. If the client must not see any of these revisions an unchecked exception must be thrown.
additionalRevisions - The additional revisions that are to be sent to the client because internal optimizers believe that they will be needed soon. If the client must not see any of these revisions they should be removed from the list.
Throws:
RuntimeException - to indicate that none of the revisions must be sent to the client. This exception will be visible at the client side!
