The TANGO IDL file : Module Tango

The fundamental idea of a device as a network object which has methods and data has been retained for TANGO. In TANGO objects are real C++/Java objects which can be instantiated and accessed via their methods and data by the client as if they were local objects. This interface is defined in CORBA IDL. The fundamental interface is Device. All TANGO control objects will be of this type i.e. they will implement and offer the Device interface. Some wrapper classes group in an API will hide the calls to the Device interface from the client so that the client will only see the wrapper classes. All CORBA details will be hidden from the client as far as possible.

Interface Tango::Device

The fundamental interface for all TANGO objects. Each Device is a network object which can be accessed locally or via network. The network protocol on the wire will be IIOP. The Device interface implements all the basic functions needed for doing generic synchronous and asynchronous I/O on a device. A Device object has data and actions. Data are represented in the form of Attributes. Actions are represented in the form of Commands. The CORBA Device interface offers attributes and methods to access the attributes and commands. A client will either use these methods directly from C++ or Java or access them via wrapper classes implemented in a API. The Device interface describes only the remote network interface. Implementation features like threads, command security, priority etc. are dealt with in server side of the device server model.

The updated Tango device interface for Tango release 7. It inherits from Tango::Device_3 and therefore supports all attribute/operation defined in the Tango::Device_3 interface.

Interface Tango::Device_5

interface Device_5 inherits from Tango::Device_4

The updated Tango device interface for Tango release 9. It inherits from Tango::Device_4 and therefore supports all attribute/operation defined in the Tango::Device_4 interface.
