Class RobotReflection

java.lang.Object

robocode.util.RobotReflection

public final class RobotReflection
extends Object

Used internally by Robocode for checking the use of reflection by robots.

When robot classes are loaded, calls to methods that use members via reflection, e.g. Method.invoke(java.lang.Object, java.lang.Object...), Field.get(java.lang.Object), and AccessibleObject.setAccessible(java.lang.reflect.AccessibleObject[], boolean), are replaced with calls to the corresponding static methods of this class, which take the member as the first parameter. These methods check that the robot is allowed to use the member, i.e. that the member belongs to a class of the robot, or that robots are allowed to use the member directly in their code. Robots should not use this class directly.
