      extended by com.jacob.com.InvocationProxyAllVariants

public class InvocationProxyAllVariants
extends InvocationProxy

This class acts as a proxy between the windows event callback mechanism and the Java classes that are looking for events. It assumes that all of the Java classes that are looking for events implement methods with the same names as the windows events and that the implemented methods accept an array of variant objects. The methods can return void or a Variant that will be returned to the calling layer. All Event methods that will be recognized by InvocationProxyAllEvents have the signature void eventMethodName(Variant[]) or Variant eventMethodName(Variant[])

Method Detail

invoke

public Variant invoke(String methodName,
                      Variant[] targetParameters)
Description copied from class: InvocationProxy
The method actually invoked by EventProxy.cpp. The method name is calculated by the underlying JNI code from the MS windows Callback function name. The method is assumed to take an array of Variant objects. The method may return a Variant or be a void. Those are the only two options that will not blow up.

Subclasses that override this should make sure mTargetObject is not null before processing.

Specified by:
invoke in class InvocationProxy
Parameters:
methodName - name of method in mTargetObject we will invoke
targetParameters - Variant[] that is the single parameter to the method
Returns:
an object that will be returned to the com event caller
