---------------------------------
Just attached a first shot on the problem. Unit tests must be added.
> SolrJ: Make DocmentObjectBinder accept getter only fields (adapter pattern)
> ---------------------------------------------------------------------------
>
> Key: SOLR-2844
> URL: https://issues.apache.org/jira/browse/SOLR-2844
> Project: Solr
> Issue Type: Improvement
> Components: clients - java
> Reporter: Jens Wike
> Priority: Minor
> Fix For: 3.5, 4.0
>
> Attachments: SOLR-2844.patch
>
>
> Our primary use case for SolrJ is to feed data into solr. We commonly use an
> adapter design pattern in our presentation or export layer in the
> application. E.g. an adapter to flatten structured relational data for books
> for an solr import might look like this:
> class Book {
> BookEntity book;
> public String getTitle() { return book.getTitle(); }
> public String getAuthorName() { return book.getAuthor().getName(); }
> public Double getMinimumPrice( { return
> priceService.calculateMinimumPrice(book); }
> }
> This is not working currently, because a setter has to be specified. So the
> workaround is to write this code:
> class Book {
> BookEntity book;
> public String getTitle() { return book.getTitle(); }
> @Field public void setTitle(String s) { }
> public String getAuthorName() { return book.getAuthor().getName(); }
> @Field public void setAutherName(String s) { }
> public Double getMinimumPrice( { return
> priceService.calculateMinimumPrice(book); }
> @Field public void setMinimumPrice(Double d) { }
> }
> So the scope of this improvement is to get rid of the dummy setters and to
> support @Field on getters directly.
> I will add a patch proposal for this later on.
