Header: IoT/Devices/ScalarDatapointServerHelper.h
Description
A scalar datapoint holding a single numeric (double) value.
In addition to the methods defined in this interface, a ScalarDatapoint implementation should expose the following properties:
- physicalQuantity (string): The physical quantity that is being measured by the datapoint, e.g. "temperature".
- physicalUnit (string): The physical unit the measured value is being represented in (e.g. "Cel" for degree Celsius). This should use the "c/s" symbols from the Unified Code for Units of Measure (http://unitsofmeasure.org/ucum.html). See the PHYSICAL_UNIT_* strings for predefined values.
- displayValue (string, optional): The current value of the datapoint, formatted as string for display purposes.

Member Functions
createRemoteObject 
static Poco::AutoPtr < IoT::Devices::ScalarDatapointRemoteObject > createRemoteObject(
Poco::SharedPtr < IoT::Devices::ScalarDatapoint > pServiceObject,
const Poco::RemotingNG::Identifiable::ObjectId & oid
);
Creates and returns a RemoteObject wrapper for the given IoT::Devices::ScalarDatapoint instance.
enableEvents
static void enableEvents(
const std::string & uri,
const std::string & protocol
);
Enables remote events for the RemoteObject identified by the given URI.
Events will be delivered using the Transport for the given protocol. Can be called multiple times for the same URI with different protocols.
registerObject
static std::string registerObject(
Poco::SharedPtr < IoT::Devices::ScalarDatapoint > pServiceObject,
const Poco::RemotingNG::Identifiable::ObjectId & oid,
const std::string & listenerId
);
Creates a RemoteObject wrapper for the given IoT::Devices::ScalarDatapoint instance and registers it with the ORB and the Listener instance uniquely identified by the Listener's ID.
Returns the URI created for the object.
registerRemoteObject
static std::string registerRemoteObject(
Poco::AutoPtr < IoT::Devices::ScalarDatapointRemoteObject > pRemoteObject,
const std::string & listenerId
);
Registers the given RemoteObject with the ORB and the Listener instance uniquely identified by the Listener's ID.
Returns the URI created for the object.
shutdown
static void shutdown();
Removes the Skeleton for IoT::Devices::ScalarDatapoint from the ORB.
unregisterObject
static void unregisterObject(
const std::string & uri
);
Unregisters a service object identified by URI from the ORB.
