Putting it on IMetadata works for me. I assume, like I think other create* methods do, this would both create and add to the set.

I thought that createMetadataItem was part of IMetdata.

The programmer should only have to implement that once, unless we think that different interfaces will have need for different classes of MetadataItem. I don't think so, and I would opt for moving the create method to the IMetadata interface. Without the create, all that's left is get/set, so I don't think there's a need for IHasMetadata. ...Greg _______________________________________________ higgins-dev mailing list higgins-dev@xxxxxxxxxxx https://dev.eclipse.org/mailman/listinfo/higgins-dev |
