Hey guys, how you doing?<div><br></div><div><div>I'm trying to achieve something that might be impossible, but before concluding that, I'd like to ask you, CDI gurus!</div><div><br></div><div>I have the following class:</div>
<div><br></div><div>public class Foo<T> {</div><div><br></div><div> public TypedQuery<T> getQuery(){</div><div><br></div><div> }</div><div><br></div><div>}</div><div><br></div><div>As you can Imagine, inside my getQuery method, I'd have to use "T.class" to make it TypedQuery. which is impossible due java generics type erasure.</div>
<div><br></div><div>so I'd have to build a private field to hold the t.class for me.</div><div><br></div><div><div>public class Foo<T> {</div><div><br></div><div> private Class<T> klass;</div><div><br></div>
<div> public TypedQuery<T> getQuery(){</div><div><br></div><div> }</div><div> </div><div> public void setKlass(Class<T> klass){</div><div> this.klass = klass;</div><div> }</div><div>}</div>
</div><div><br></div><div>The problem is that forcing this 'setKlass' feels very ugly to the api, and it's not very error prone, since one could easily forget to set this configuration.</div><div><br></div><div>
So I had an Idea: force the setKlass inside the constructor:</div><div><br></div><div><div>public class Foo<T> {</div><div><br></div><div> private Class<T> klass;</div><div> </div><div> public Foo(Class<T> klass){</div>
<div> this.klass = klass;</div><div> }</div><div><br></div><div> public TypedQuery<T> getQuery(){</div><div><br></div><div> }</div><div><br></div><div>}</div></div><div><br></div><div>Unfortunatelly, this breaks cdi, since it cannot inject it anymore. At least AFAIK.</div>
<div><br></div><div>So, is there a way out of this? maybe using a secret solder feature?</div></div>
