</div>
</div> <p style="margin: 10px 0 0">All of which will work thanks to the <tt>FullTextQuery</tt> returned by <tt>fullTextSession</tt> being a raw type. Even if there will be compiler warning.</p> <p style="margin: 10px 0 0">With our change, the snippets of code above will give users a compilation error due to incompatible types. Users will have to adapt their code and add explicit casts... (even in our tests, this translates into more than 90 compilation errors)</p> <p style="margin: 10px 0 0">To sum up the problem, we can't fix the "mutable return type" issue without breaking the API: we'd need to remove the <tt>setProjection</tt> method. So we definitely cannot make <tt>createFullTextQuery</tt> return a typed (<tt><T></tt>) query. But adding <tt><Object></tt> or <tt><?></tt> to the returned <tt>FullTextQuery</tt> type will break existing user code, including code compatible with 5.7.0.CR1.</p> <p style="margin: 10px 0 0">So the two solutions I see are:</p> <p style="margin: 10px 0 0">1. Leave <tt>createFullTextQuery()</tt> as is, returning a raw <tt>FullTextQuery</tt>.<br> 2. Add <tt><Object></tt> or <tt><?></tt> to the returned <tt>FullTextQuery</tt> type, but release a CR2 or somehow warn users.</p> <p style="margin: 10px 0 0">Also, maybe we should introduce other methods, beside createFullTextQuery(), to support typed queries? E.g. <tt>createTypedFullTextQuery</tt>? Then it'd be up to the user to provide the correct type, and we could add some early runtime checks to ensure setProjection/setResultTransformer are used properly. It'd be a shame to introduce new API so late in the release cycle, though, particularly considering that these APIs will have to go in HSearch 6.</p> <p style="margin: 10px 0 0">By the way, the current situation in ORM isn't so bright as I understood from Steve's explanations: there is currently (in ORM 5.2) no replacement for the deprecated <tt>setResultTransformer</tt> method, so anyone wanting to transform results will have to use this non-typesafe API...</p> <p style="margin: 10px 0 0"><a href="https://hibernate.atlassian.net/secure/ViewProfile.jspa?name=sanne" class="user-hover" rel="sanne" style="color: #3b73af; text-decoration: none">Sanne Grinovero</a> WDYT?</p> </td>
