The authors' exact insurance of the IDL-to-C++ mapping strikes past the mechanics of the APIs to debate themes corresponding to capability pitfalls and potency. An in-depth presentation of the hot moveable item Adapter (POA) explains how one can benefit from its various beneficial properties to create scalable and high-performance servers. moreover, particular dialogue of complicated subject matters, akin to rubbish assortment and multithreading, presents builders with the data they should write advertisement applications.

Other highlights

* In-depth assurance of IDL, together with universal idioms and layout trade-offs
* entire and distinctive factors of the existence Cycle, Naming, buying and selling, and occasion Services
* dialogue of IIOP and implementation repositories
* perception into the dynamic elements of CORBA, equivalent to dynamic typing and the recent DynAny interfaces
* suggestion on choosing acceptable software architectures and designs
* exact, moveable, and vendor-independent resource code

Example text

To send a message to an object, a client must hold an object reference for the object. The object reference acts as a handle that uniquely identifies the target object and encapsulates all the information required by the ORB to send the message to the correct destination. When a client invokes an operation via an object reference, the ORB does the following: Locates the target object Activates the server application if the server is not already running Transmits any arguments for the call to the object Activates a servant for the object if necessary Waits for the request to complete Returns any out and inout parameters and the return value to the client when the call completes successfully Returns an exception (including any data contained in the exception) to the client when the call fails The entire request invocation mechanism is completely transparent to the client, to whom a request to a remote object looks like an ordinary method invocation on a local C++ object.

30 IT-SC book: Advanced CORBA® Programming with C++ In CORBA, object interfaces are defined in the OMG Interface Definition Language (IDL). Unlike C++ or Java, IDL is not a programming language, so objects and applications cannot be implemented in IDL. The sole purpose of the IDL is to allow object interfaces to be defined in a manner that is independent of any particular programming language. This arrangement allows applications implemented in different programming languages to interoperate. The language independence of IDL is critical to the CORBA goal of supporting heterogeneous systems and the integration of separately developed applications.

7 Summary The problems associated with distributed heterogeneous computing are with us for the foreseeable future. Computer networks will continue to be heterogeneous for some time to come because of continued advances in computing hardware, networking, and operating systems. This heterogeneity makes the development, deployment, and maintenance of networked applications difficult because of the overwhelming number of low-level details that must be considered and addressed. 45 IT-SC book: Advanced CORBA® Programming with C++ CORBA provides the abstractions and services you need to develop portable distributed applications without worrying about low-level details.
