BeforeSaveEntities() protected method

Called after BeforeSaveEntity, and before saving the entities to the persistence layer. Allows adding, changing, and removing entities prior to save. The base implementation returns the result of BeforeSaveEntitiesDelegate, or the unchanged saveMap if BeforeSaveEntitiesDelegate is null.
protected BeforeSaveEntities ( Dictionary saveMap ) : List>.Dictionary
saveMap Dictionary A List of EntityInfo for each Type
