[Class] Accessing private fields/ calling private methods.

I have written a simple utility class that i call ClassUtils for getting info from private fields and to run private methods. This is useful if you have to get stuff from a private field in the minecraft source. For example i used it in CrowdControl to set a ghasts target manually.

Example:

Code:java

 
EntityGhast ghast = (EntityGhast) ((CraftGhast)entity).getHandle();
try {
    ClassUtils.setPrivateField(ghast, "target", e.getHandle());
} catch (Exception ex) {
    System.out.println("Error setting ghast target!");
}
 

Class:

Code:java

 
import java.lang.reflect.Field;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
 
/**
 * A utility class for accessing private fields, and calling private methods
 * @author WinSock
 * @version 1.0
 */
public class ClassUtils {
    @SuppressWarnings("unchecked")
    public static <T> T getPrivateField(Object object, String field) throws SecurityException, NoSuchFieldException, IllegalArgumentException, IllegalAccessException {
        Class<?> clazz = object.getClass();
        Field objectField = clazz.getDeclaredField(field);
        objectField.setAccessible(true);
        return (T)objectField.get(object);
    }
    public static void setPrivateField(Object object, String field, Object value) throws SecurityException, NoSuchFieldException, IllegalArgumentException, IllegalAccessException {
        Class<?> clazz = object.getClass();
        Field objectField = clazz.getDeclaredField(field);
        objectField.setAccessible(true);
        objectField.set(object, value);
    }
    public static Object callPrivateMethod(Object object, String method, Object... params) throws SecurityException, NoSuchMethodException, IllegalArgumentException, IllegalAccessException, InvocationTargetException {
        Class<?> clazz = object.getClass();
        Class<?>[] paramClasses = new Class<?>[params.length];
        for (int i = 0; i < params.length; i++) {
            paramClasses = params.getClass();
        }
        Method m = clazz.getDeclaredMethod(method, paramClasses);
        m.setAccessible(true);
        return m.invoke(object, params);
    }
}
 
 

 

I got an error line 29 : Type mismatch: cannot convert from Class<capture#6-of ? extends Object[]> to Class<?>[]

 

I think that is a copy error try copying from here:
