Implements abstract bsh.ClassGenerator.invokeSuperclassMethod.

Doc from bsh.ClassGenerator.invokeSuperclassMethod.

Invoke a super.method() style superclass method on an object instance. This is not a normal function of the Java reflection API and is provided by generated class accessor methods.

public static Object invokeSuperclassMethodImpl(BshClassManager bcm, Object instance, String methodName, Object[] args) throws UtilEvalError, ReflectError, InvocationTargetException

public void setInstanceNameSpaceParent(Object instance, String className, NameSpace parent)

Implements abstract bsh.ClassGenerator.setInstanceNameSpaceParent.

Change the parent of the class instance namespace. This is currently used for inner class support.

Note

This method will likely be removed in the future.
