Class Capabilities

  • public class Capabilities
extends java.lang.Object
    The map of extended features supported by the runtime in which we live.

    This class should be independent of all other bsh classes!

    Note that tests for class existence here do *not* use the BshClassManager, as it may require other optional class files to be loaded.

      Use direct Class.forName() to test for the existence of a class.
      static boolean haveAccessibility()
      If accessibility is enabled determine if the accessibility mechanism exists and if we have the optional bsh package to use it.

      • canGenerateInterfaces

        public static boolean canGenerateInterfaces()

      • haveAccessibility

        public static boolean haveAccessibility()
        If accessibility is enabled determine if the accessibility mechanism exists and if we have the optional bsh package to use it. Note that even if both are true it does not necessarily mean that we have runtime permission to access the fields... Java security has a say in it.

      • classExists

        public static boolean classExists​(java.lang.String name)
        Use direct Class.forName() to test for the existence of a class. We should not use BshClassManager here because: a) the systems using these tests would probably not load the classes through it anyway. b) bshclassmanager is heavy and touches other class files. this capabilities code must be light enough to be used by any system **including the remote applet**.
