Question

The code snippet below causes this warning in NetBeans 6.9.

[rawtypes] found raw type: org.openide.nodes.PropertySupport.Reflection
  missing type parameters for generic class org.openide.nodes.PropertySupport.Reflection<T>

Property dataProp = new PropertySupport.Reflection(t, dataStore.getFloat3DClass(),
                        workingData);

/**
 * Gets the Class object associated with the primitive 3d float array (i.e., float[][][]).
 *
 * @return  the Class object.
 */
public Class<?> getFloat3DClass()
{
    if (class3DFloat == null)
    {
       try
       {
           class3DFloat = Class.forName("[[[F");
       }
       catch (ClassNotFoundException ex)
       {
           Exceptions.printStackTrace(ex);
       }
    }

    return class3DFloat;
}

At runtime getFloat3DClass() returns a Class object whose value is class float[][][]. How do I specify this at design time and avoid this warning?

Answer 1

You’re working too hard. Don’t use dataStore.getFloat3DClass() when you’re making a PropertySupport.Reflection, use float[][][].class and it will work. And the value will be cached by the runtime for you too.
