TD.net to JSON

This Camel component will convert TD.net messages in XML format in to a lightweight JSON format.

If you don't know what TD.net is, or you don't have access, then this component is not for you.

The following message types are supported:

• Train Describer - CA, CB, CC, CT, SF, SG and SH
• Train Movement - all message types (excluding UnidentifiedTrainMovement)

Usage

Spring XML

<route id="testRoute">
  <from uri="queue:input"/>
  <to uri="tdToJson"/>
  <to uri="queue:output"/>
  </split>
</route>

Fluent Builders

RouteBuilder builder = new RouteBuilder() {
  public void configure() {
    Processor tdMessageProcessor = new TdMessageConverter();
    from("queue:a")
        .process(tdMessageProcessor))
        .to("queue:b");
  }
}

Train Movement data mapping

Train movement data is converted to the same JSON format as used by the Network Rail Data Feeds platform, making it easy to migrate between platforms.
