RE: About DOM and CORBA
Hi Anders, Many thanks, this is the first useful post I get on the subject. Thanks again Didier PH Martin mailto:martind@n... http://www.netfolder.com -----Original Message----- From: Anders W.

This is what Microsoft have implemented within their COM. Some Corba's have however implemented "colocation" which is a shortcut route so marshalling is not performed when calling objects within the same adress space. See <http://www.cs.wustl.edu/~schmidt/TAO.html> for an example. Here is a list of implementation options (faster to slower) 1.Private Component calls (not calling across Interfaces) No time penalty, same as normal C or C++ calls 2.Public Interface calls (calling other components using interface pointers) Same as C++ virtual function calls, slightly slower than above The MS COM and Mozilla way. 3.Optimized In-process Collocation call, to a Corba Object Adapter (OA) managed object. Call routed directly to object. This is outside the Corba spec. 4.In-process Collocation call, to a Corba OA managed object No marshaling, but call put in queue or rerouted by OA according to Corba guidelines. Corba Components implemented in same language. 5.Process to Process call, using Corba OA's Parameter marshaling and IIOP calls. Corba Components may be implemented in different languages. 6.Inter Machine Process to Process call, using Corba OA's Parameter marshaling, IIOP calls and network traffic. /anders -- /_/_/_/_/_/_/_/_/_/_/_/_/_/_/ / Financial Toolsmiths AB / / Anders W.
