public delegate void StaticFilterMapFunc (Model orig_model, FilterModel filter_model, void* data)
Function used to collect the rows from a model that should be included in a FilterModel.
To add rows to filter_model use the methods append_iter,
prepend_iter,
insert_iter, and insert_iter_before.
The iteration over the original model is purposely left to the map func in order to allow optimized iterations if the the caller has a priori knowledge of the sorting and grouping of the data in the original model.
| orig_model |
The model containing the original data to filter |
| filter_model |
The model that will contain the filtered results. The filter func must iterate over |
