    Description copied from interface: AsyncEventListener
    
    Process the list of AsyncEvents. This method will asynchronously be called when events are queued to be processed. The size of the list will be up to batch size events where batch size is defined in the AsyncEventQueueFactory.
    
    Specified by:
    
    processEvents in interface AsyncEventListener
    
    Parameters:
    
    events - The list of AsyncEvent to process
    
    Returns:
    
    boolean True represents whether the events were successfully processed, false otherwise.
