Hi all,
Passing arrays as parameters to a method
----------------------------------------
Doing this C++ differs from Java. Usually in C++ we pass the size of the
array in another parameter so that inside the method it know the size of the
array.
In Java this is not a problem because an Array itself is a class that has the
size. So a method in java,
int EchoIntArray(int []) corresponds to int EchoArray(int [], int)
in C++.
Suppose some one needs to write a web service for this method and the method
signature that the WSDL describes corresponds to the method signature in Java
exactly but not the C++ one.
So how should a C++ developer implement his service corresponding to the
WSDL ?
This way that we (Axis C++) asks the C++ web service developer should be
decided in order to improve Wrapper Class Generator (WCG) to handle passing
and returning arrays from methods.
I find that we can give 2 solutions,
1. Introduce Axis C++ own Array class. So the method signature becomes
int EchoIntArray(AxisArray a)
2. Ask the C++ developer to specify the meaning of other parameters by using
a predefined Axis C++ macro. Then the method signature becomes,
int EchoIntArray(int [], ARRAYINSIZE int);
Which is the best option to choose. IMO I like second.
Also if you find any other solution please discuss.
Comments on this is very much appreciated.
Thanks,
Susantha.
