Channel Config File

The connectivity configuration file can be used to store channel feed parameters for all market data channels in the some environment (Test or Production).

For example:

<configuration environment="TEST">
  <channel id="80">
    <instrument>
      <a ip="233.205.192.108" port="33080"/>
    </instrument>
    <snapshot>
      <a ip="233.205.192.106" port="34080"/>
    </snapshot>
    <incremental>
      <a ip="233.205.192.107" port="31080"/>
      <b ip="233.205.192.142" port="31080"/>
    </incremental>
  </channel>
  ...

The path to the configuration file is passed to the Handler settings as follows:

    HandlerSettings settings;
    settings.loadFeeds(80, PATH_TO_CHANNEL_CONFIG_FILE);

Channel Ids

If it is necessary to get ids for all chanels from the connectivity configuration file, OnixS::B3::MarketData::UMDF::HandlerSettings::gatherChannelIds(std::vector<int>& channelIds, const std::string& channelConfigFile) can be used.

    std::vector<int> channelIds;
    HandlerSettings::gatherChannelIds(channelIds, PATH_TO_CHANNEL_CONFIG_FILE);
