/**
|
||
|
* This is the new TACO interface defined in IDL. New TACO (or TANGO)
|
||
|
* is a total rethink of (old) TACO which was based on remote procedure
|
||
|
* calls.
|
||
|
* TANGO is an extension of old TACO.
|
||
|
* The fundamental idea of a device as a network object which
|
||
|
* has methods and data has been retained. However
|
||
|
* in TANGO objects will be real C++/Java objects which can be instantiated
|
||
|
* and accessed via their methods and data by the client as if they were local
|
||
|
* objects.
|
||
|
* Certain aspects of the old DSAPI application programmer's
|
||
|
* interface have been suppressed in order to simplify the client (e.g. import,
|
||
|
* free, data collector api).
|
||
|
* Features which have been considered missing in old TACO have been added
|
||
|
* e.g. signals, events and groups.
|
||
|
* Asynchronism and groups have been foreseen right from the beginning
|
||
|
* this time.
|
||
|
* 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.
|
||
|
* New classes of control objects e.g. PowerSupply, will be created by
|
||
|
* wrapping the Device class appropriately.
|
||
|
* The wrapper class will hide the calls to the Device interface from
|
||
|
* the client so that the client will only see the wrapper class.
|
||
|
* All CORBA details will be hidden from the client as far as possible.
|
||
|
* Generic clients will use the Device interface directly.
|
||
|
* In addition to Device TANGO offers the interfaces Monitor,
|
||
|
* GroupDevice and GroupSignal.
|
||
|
* These interfaces implement TANGO services for monitoring and
|
||
|
* executing grouped accesses to device/signals.<BR><BR>

/**

|
* 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 a wrapper class.
|
||
|
* 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.
