Programmatic Lookup with incomplete Qualifiers

ahhughes Nov 30, 2011 11:57 PM

Hi Again,

I'm stuck and need help. If I have the following Qualified bean...

@Named("ClarkKent")
@SuperHeroType(SuperMan.class)
public class SuperManBean implements SuperHeroAlterEgo<SuperMan> {}

Question

How can I programmatically lookup SuperManBean with either the String ClarkKent OR superHero.getClass(), which is of course SuperMan.

I have tried to lookup by NameLiternal only (I can't provide a SuperHeroTypeLiteral here)

@Inject @Any Instance<SuperHeroAlterEgo<SuperHero>> source;
source.select(new NamedLiteral("ClarkKent")); //and similar for

I have also tried by new SuperHeroTypeLiteral(superHero.getClass()) only - I dont have a NamedLiternal here

@Inject @Any Instance<SuperHeroAlterEgo<SuperHero>> source;
source.select(new SuperHeroTypeLiteral(superHero.getClass())); //and similar for

But both have unsatisfied dependencies. Seems that you need both qualifiers no @Any and nothing else :'(

Help would be excellent :)

What's wrong with

@Inject @Named(ClarkKent) SuperHeroAlterEgo superman;

Thanks Justin, but that doesn't correlate to my question. That's not programmatic lookup and at runtime I have either...

String someonesName = ...;

OR

Class<? extends SuperHero> superHeroClass = ...;

NEVER BOTH

Which means I can't do programmatic lookup with ALL qualifiers, only ever one of them (Named or SuperHeroType).

I'll keep hoping there is a solution for this.
