A little confused about this

Code:

---


class xsd__anyType {
public:
    char *__item;
};


class ArrayOf__xsd__anyType : public xsd__anyType {
public:
    xsd__anyType **__ptr;
    int __size;
};

---

Now I want to initialize a dynamic array (a pointer) that I have,

Code:

---

ArrayOf__xsd__anyType* properties;

---

And I am lost :confused:

So, an array_of_something IS-A something?

Yeah, that is the confusing part.
Plus I am not able to find out, how to, initialize the properties array?

Seems broken to me. And....why not just use std::vector<any_type>?

I had a WSDL file, from which I created the above C++ code using a generator tool.
And it is way too much work to build a handwritten client for that 5000+ lines WSDL file. So, I am using above auto-gen code. I just need to cope up with it. Somehow.

Is this gSOAP perhaps? If so, docs are here. I can't be much help directly as I've only written a gSOAP server, and in pure C at that, but thought maybe a pointer (hah) to the docs might be helpful.

Yes. This was generated by gSOAP. Thanks for link.

And if some of the more experienced C++ users feel, that, the definitions created by gSOAP are ok, not necessarily a good example, but, if the definitions are correct and compilable, then, please let me know how to initialize the properties array here?

In essence, you want to set the value of
char *__item;
xsd__anyType **__ptr;
int __size;
When creating the class or array?
This is not possible with dynamic memory to my knowledge.
However, the solution is simple. Design a new function that sets all of these items in a class:

Code:

---

class A { public: int a, b, c; };

void foo(A* pA, int a, int b, int c)
{
        pA->a = a;
        pA->b = b;
        pA->c = c;
}

int main()
{
        A* pA = new A[10];
        for (int i = 0; i < 10; i++)
                foo(pA, 1, 1, 1);
        delete [] pA;
}

---

I could come up with this solution:

Code:

---

ArrayOf__xsd__anyType* properties = new ArrayOf__xsd__anyType;
int size = 2;
xsd__anyType** list = new xsd__anyType*[size];
for (int i=0; i<size; i++) {
        list[i] = new xsd__anyType;
}

list[0]->__item = qstrdup("url:whateveryoururlis");
list[1]->__item = qstrdup("useFixed:1");

properties->__ptr = list;
properties->__size = size;

---

Besides being messy. Is there anything else, conceptually, wrong here?

What the heck is qstrdup? I'd be worried if it allocates new memory using new/malloc. You've got too many pointers all over the place.

Allocates space for a copy of src, copies it, and returns a pointer to the copy. If src is 0, it immediately returns 0.
Ownership is passed to the caller, so the returned string must be deleted using delete[].

So I can delete it later using delete[]. But I need it to be working first.
Tell me, if, there is, anything, wrong here in my initialization?

Too messy. Get a debugger and try. You're most likely going to have tons of memory leaks.

Memory leaks, for now, is a secondary issue. I will plug the holes, later.
Messy, of course, so many manual allocations, no use of STL facility. But since WSDLs are programming language independent, so, I think my tool could not use better features from STL.

Anyway. I am not getting anywhere. I just needed a confirmation, about, every thing being initialized properly.

Thanks all.

Write a unit test for it. I'd recommend UnitTest++ as the test framework.

Language independent? How can anything be language independent?
I'd really worry about getting some C++ tool instead of half-witted C crap that produces unreadable, unmaintainable code mess.
Well, hopefully you'll have better luck next time you have to do something like this. You can always hope.

WSDL is Web Services Description Language, and it presents the web services offered by an application in plain XML format. After that any application, running on any OS, written in any programming language can, simply, use these web services, like, say, a function in a DLL.

Thanks Elks. I will try that.

Sure, but the code is generated - it cannot be language independent.

Did you look at the samples? dimeclient.cpp in the samples/dime directory has some arrays that might be of some help.

Also, how did you call wsdl2h and soapcpp2? What exactly were the command lines and any errors which may have occurred? Are you using the latest version of gSOAP?

There's a Yahoo gSOAP group which is monitored by the author. You may want to look there as well.

Thank you Riches.
I will try those places, that, you suggested.

Actually, right now, even after initializing it properly, my web service request is failed.
I hope what you suggested, will, be more help to me.

Hi Riches,

This is version info:

wsdl2h version 1.2.91
soapcpp2 version 2.7.91

I used this command line while generating files with gSOAP:

wsdl2h -s -o fileName.h fileName.wsdl
soapcpp2 -Ic:\dev\gsoap-2.7\import fileName.h

I also checked the example that you suggested, it was simpler, than, what I am having problems with.

I will try Yahoo group for gSOAP as well.
