Now we'll expand on the earlier weather monitoring example, demonstrating how to create, subscribe to and publish messages on a topic. We use the following Slice definitions in our example:
Slice
struct Measurement
{
string tower; // tower id
float windSpeed; // knots
short windDirection; // degrees
float temperature; // degrees Celsius
}
interface Monitor
{
void report(Measurement m);
}
Monitor is our topic interface. For the sake of simplicity, it defines just one operation, report, taking a Measurement struct as its only parameter.
