C# 클래스 Examples.ControlClientUpdatingJSONTopics

This example shows a control client creating a JSON topic and sending updates to it. There will be a topic for each currency for which rates are provided. The topic will be created under the FX topic - so, for example FX/GBP will contain a map of all rate conversions from the base GBP currency. The rates are represented as string decimal values (e.g. "12.457"). The addRates method shows how to create a new rates topic, specifying its initial map of values. The changeRates method which takes a map shows how to completely replace the set of rates for a currency with a new map of rates. The changeRates method which takes a string shows an alternative mechanism where the new rates are simply supplied as a JSON string. Either of the changeRates methods could be used and after the first usage for any topic the values is cached, and so subsequent set calls can compare with the last value and send only the differences to the server.
