Class RobotFileAccess

java.lang.Object

robocode.util.RobotFileAccess

public final class RobotFileAccess
extends Object

Used internally by Robocode for checking file access made by robots.

When robot classes are loaded, calls to methods of File that modify files or read information about files are replaced with calls to the corresponding static methods of this class. These methods check that the robot is only modifying files in its own data directory, and only reading files in its own root package directory or data directory. Robots should not use this class directly.
