Dmitry Geraskov commented on JBIDE-4269:
----------------------------------------

By the way all subclasses of GenericExporter uses iterator of PojoClass eslements to make their export with different templates.
Hbm2DDLExporter, HibernateConfigurationExporter, QueryExporter produces only 1 file as I think. We do not need to make file content filtering we only need to make *files* filtering as I think, so can forget about this exporters as I think.

> Now exporter uses Configuration object to get for example pojo's for generation.
> After this it calls generation for each of them.
> We need to add some filter for this.
> First place for such injection is ArtifactCollector as developer can easily specify subclass of this class and set it to exporter.
> Also TemplateProducer which used for files generating always gets ArtifactCollector object in constructor from exporter and has access to it.
> I' going to add methods filter(Map context), setFilter(Filter) to ArtifactCollector class and call it when necessary in template producer.
> Method 'filter' by default will not filter out anything. Non default realizations should use context map to get any objects which is passed to template producer.
> Second variant is to add Filter field to Generic exporter and call for filtering in GenericExporter.exportPOJO() method(or in each realization of ModelIterator.process()).
> I prefer first way.
