O2GResponseReaderFactory

The class creates readers to process the content of the trading server responses.

An O2GResponse object contains a response received from the trading server. To process the contents of the response object, you must use an appropriate reader based on the response type. For the list of the response types, refer to the O2GResponseType description. The O2GResponseReaderFactory class provides methods to create readers for all the response types.

O2GResponseReaderFactory responseFactory = mSession.getResponseReaderFactory();
