------------------------------------
Summary: Allow out-of-order insertion into DI lists
Key: CAY-2029
URL: https://issues.apache.org/jira/browse/CAY-2029
Project: Cayenne
Issue Type: Task
Reporter: Andrus Adamchik
Assignee: Andrus Adamchik
We need that per CAY-2028. The API might look like this:
{noformat}
ListBuilder.add(label, object).after(label1);
ListBuilder.add(label, object).before(label2);
{noformat}
So each item can optionally have a String label. If no label is used on
insertion (existing API), the label can be generated semi-randomly. Then later
the label can be used to refer to a position in the list without knowing the
position, just to specify relative ordering.
The reason for using String labels instead of letting the caller to inspect the
contents of the list directly is that the DI list contains mostly Providers,
usually multiple Providers wrapping each other. So looking at that directly
makes little sense.
