addListener

public void addListener(java.lang.String iidStr,
                        java.lang.Object theListener,
                        java.lang.Object theSource)
                 throws java.io.IOException

Description copied from class: Dispatch

Adds a Java object to be a listener for a specific kind of event generated by the COM object. when you wish to invoke method on the COM object using IDispatch (not using custom marshalling).

Overrides:

addListener in class Dispatch

Parameters:

iidStr - the ID of the outgoing interface, implemented by the listener

theListener - the object to be informed of the events

theSource - the proxy class that represents the COM class that is the source of the events

Throws:

java.io.IOException

removeListener

public void removeListener(java.lang.String iidStr,
                           java.lang.Object theListener)
                    throws java.io.IOException

Description copied from class: Dispatch

Removes a Java object as a listener to events generated by a COM object. when you wish to invoke method on the COM object using IDispatch (not using custom marshalling).

Overrides:

removeListener in class Dispatch

Parameters:

iidStr - the ID of the outgoing interface, implemented by the listener

theListener - the object that no longer wishes to be informed of the events

Throws:

java.io.IOException
