An Implementation of Valuetype Object in CORBA IDL Compiler
Yun Wang · Computer Technology and Development · 2006
The valuetype is a new data structure in CORBA specification.With the help of valuetypes,it can pass an object by value of CORBA-based applications.With the growth of the application domain of CORBA,many applications need object by value.Traditionally,CORBA does not provide the ability. The paper introduces valuetype concept,then describes the interaction of OBV(Object By Value).This interaction needs a compiler and ORB that support passing object by value.The main work will be accomplished by C plus plus code created by the compiler.ORBUS IDL compiler and ORB are extended for OBV.The implementation of this extension in ORBUS IDL compiler is discussed in detail.Performance test shows the feasibility of the interaction.
