Corba

CORBA Device Driver allows Iotellect Server to communicate with any CORBA-based application. CORBA is a standard defined by the Object Management Group (OMG) designed to facilitate the communication of systems that are deployed on diverse platforms.

The driver has the following capabilities:

• Compiling IDL files;

• Remote invocation of methods described in IDL files.

None defined.

None defined.

Connection settings define how Iotellect Server communicates with a certain CORBA application. These settings may be accessed using Edit Device Properties action of Device Context. Here is a list of available connection properties:

Setting	Description
Connection Type	Defines the type of connection to the remote CORBA-based application. Three types of connection are now available: corbaloc, corbaname and IOR File.
Corbaloc	This field becomes available when "Corbaloc" connection type is selected. Syntax: corbaloc:<iiop>:<host>:<port>/<object key>. Parameter <iiop> can be omitted.
		Example: corbaloc::127.0.0.1:52486/NameService
Corbaname	This field becomes available when "Corbaname" connection type is selected. Syntax: corbaname::<host>:<port>/<object key>#<object name>.
		Example: corbaname::127.0.0.1:52486/NameService#Server
IOR File	This field becomes available when "IOR File" connection type is selected. IOR is a stringified reference that uniquely identifies an object on a remote CORBA server. IOR file can be provided by CORBA application developer.

This is a tabular setting defining what IDL files will be used while working with CORBA object. IDL is a specification language used to describe a software component's interface. IDL files describe an interface in a language-independent way, enabling communication between software components that do not share a language – for example, between components written in C++ and components written in Java.

Some IDL files may depend on each other. In this case, if some of the dependent files are omitted in the IDL table, an error will occur.

Assets are not supported by the driver.

No settings are provided by the driver.

The number and functionality of operations depend on IDL files specified in device properties.

During the connection, driver checks and compiles the set of CORBA IDL files.

As the result, the set of Device functions matching remote object methods will be created. These methods determine the functionality of the remote CORBA object. This allows users to send requests to the CORBA server.

Any Device function call is bridged to a CORBA method call. Iotellect Server uses a function input Data Table to construct CORBA objects that are served as input parameters. Resulting CORBA objects are converted to an output Data Table.

No events provided by the driver.

The driver doesn't perform any connection establishing/testing. Any CORBA device is always Online, despite individual CORBA calls may fail due to network problems.

This driver does nothing during periodic synchronization.
