access private static class

Recommended Posts

I have found the following class.

package net.minecraftforge.client.model;
public final class ModelLoader extends ModelBakery {
	private static final class WeightedRandomModel implements IModel {
		private final List<IModel> models;
	}
}

 

I have an IModel object and I would like to access the models field. To do this, I must cast the object to ModelLoader.WeightedRandomModel.

How can I modify WeightedRandomModel to be public?

 

I have had no success with reflection or access transformers so far.

I am not familiar with reflection. How would I do something like this with reflection?

public void doSomething(IModel model) {
	WeightedRandomModel wModel = (WeightedRandomModel) model;
	List<IModel> list = wModel.models;
	//Do something with list
}

 

Can you provide an example?

At runtime the variable models holds all the data for all blocks in the game. I am attempting to write a rendering engine, and I need the shape of the blocks to do this.

 

The interface IModel has 3 classes that implement it. Only one of these contains the variable 'models'. I have verified that 'model' is of the class 'WeightedRandomModel'. The compiler informs me that 'WeightedRandomModel' is not visible and I can't cast 'model' to it. I have read the reflect tutorial, but it doesn't seem to help my situation. Class.cast() deosn't seem to do what I want either.

WeightedRandomModel wModel = (WeightedRandomModel) model; //Compiler error

 

I would like to read all of the data in 'models', but I don't know how to access it.

When I use

Class c = model.getClass();
c.getDeclaredField("models").setAccessible(true);
c.getDeclaredField("models").get(model);

it throws

java.lang.IllegalAccessException: can not access a member of class net.minecraftforge.client.model.ModelLoader$WeightedRandomModel with modifiers "private final"

It looks like you've solved the Forge mysteries and need Java help. Search online for how reflection is used to access private fields.

 

If you want to learn how Forge might reach your goal via a different route, then tell 7 what you are aiming for.

The debugger is a powerful and necessary tool in any IDE, so learn how to use it. You'll be able to tell us more and get better help here if you investigate your runtime problems in the debugger before posting.
