after i have sended a batch of item-request(marketPrice) ,am i supposed to receive the responses by the function:processEvent() automatically? And i need to get the information including itemname, bid/ask, time field, i have seen the examples which just decode all the fields out, so how can i get all these data? By the means of compare the Strings such as "bid" with the fieldEntry name? In addition, how can i get the itemName , from the content of the event variables?
