Class Diagram

Java Document (Java Doc)

java.lang .Object

bsh .Capabilities

Capabilities

public class Capabilities (Code)

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.

Inner Class :public static class Unavailable extends UtilEvalError

Method Summary
public static boolean	canGenerateInterfaces()
public static boolean	classExists(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.
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...
public static boolean	haveSwing()
public static void	setAccessibility(boolean b)

Method Detail

canGenerateInterfaces
public static boolean canGenerateInterfaces()(Code)

classExists
public static boolean classExists(String name)(Code)
	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.

haveAccessibility
public static boolean haveAccessibility()(Code)
	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. See Also: bsh.ReflectManager

haveSwing
public static boolean haveSwing()(Code)

setAccessibility
public static void setAccessibility(boolean b) throws Unavailable(Code)
