Example
let command = new Command("add", null, (correlationId, args, callback) => { let param1 = args.getAsFloat("param1"); let param2 = args.getAsFloat("param2"); let result = param1 + param2; callback(null, result); }); command.execute( "123", Parameters.fromTuples( "param1", 2, "param2", 2 ), (err, result) => { if (err) console.error(err); else console.log("2 + 2 = " + result); } ); // Console output: 2 + 2 = 4ICommand
