Spawner spawning custom entities

I've been searching on the Internet, to find a solution to my problem, but didn't find anything, so i'll ask it here: How can you set a spawner block's entity's data? For example, lets say i have an armor stand with a stone on it's head. How could i modify a spawner in such a way, to set the armor stand's head item to be a stone?

 

1. ((CreatureSpawner) <your block>.getState()).setSpawnedType(<some entity type>);
   
   So far as I know you can't do anything more

 

@MrGazdag
If your wishing to do custom entities you are going to need to do the following:

1. Make a custom entity
2. Make an instance of the custom entity such as "CustomEntityClass en = new CustomEntityClass(stuff);
3. Under that make a Entity variable such as "Entity bukkiten = en.getBukkitEntity();" This here returns the entity that the CustomEntity is.
4. After that you'll set the spawner's data such as what @PikaThieme had said. "((CreatureSpawner)<your block>.getState()).setSpawnedType(bukkiten))

If @PikaThieme 's method doesn't work just search up on how to set a spawner type.
If the problem persists, please reply with your recent code.

Hope this helps!

@AdamDev Sadly, CreatureSpawner.setSpawnedType() only accepts the enum EntityType, not entities itself i think

 

@MrGazdag
Well, for me I don't know much else unless you can try doing bukkiten.getType()? It would make sense but currently I can't test or see if it's true.
