How do intercept annotations?

[weitzhandler]

Hi,

I set up my model adding custom annotations to some entities with the fluent API in the OnModelCreating call.
How can I intercept this data when generating the tables when overriding the Generate methods?

Please see this issue: #1203

Ok got it

protected override void Generate(CreateTableOperation operation, IModel model, 
  MigrationCommandListBuilder builder)
{
  var entity = model.GetEntityTypes().Single(et => et.Relational().TableName == operation.Name);
  var annotations = entity.GetAnnotations().Where(an => an.Name.StartsWith(myAnnotationScope));
  // do my stuff
}

But it would be nice to have it documented somewhere, @divega @AndriySvyryd.

Is it possible to do this if you are overriding Generate with the base MigrationOperation? I would like to be able to get the entity and their annotations for all operations not just CreateTable.
