Class MicrosoftSystemAccess

java.lang.Object
  opencard.core.util.SystemAccess
      opencard.opt.ms.MicrosoftSystemAccess

public class MicrosoftSystemAccess
extends SystemAccess

Singleton that provides access to protected system resources like file I/O, properties, native code under Microsoft browsers. Thread safe: each thread can only access its own SystemAccess class.
To run OpenCard under a Microsoft browser install the browser specific SystemAccess class in the applets init() method as follows:
opencard.core.util.SystemAccess sys = opencard.opt.ms.MicrosoftSystemAccess(); opencard.core.util.SystemAccess.setSystemAccess(sys);
