[cdt-dev] Resolving and listing fields of a struct

[Jens Frieben <jens.frieben@xxxxxxxxxxxxxxxxx>]

Hi,

I am trying to programmatically list
all types used as parameters in function calls like 'AddPortInfo("myperson",
this->aPersonField);'

The 'aPersonField' is defined in a header
file via 'personStruct aPersonField;'

I index the project and create an AST
of the currently opened file. Via a visitor, I find all FunctionCallExpressions,
and the necessary fields. I now face the problem of finding the definition
of the Struct in the header files to list all fields of that struct. 

struct personStruct{
    int   age;
    float weight;
    char  name[25];
  };

Can someone point me in the right direction
how to search the index for the declaration, so that I can list the fields
in the struct? I am currently trying to get this information by using the
index and bindings. However, this is not working.

IASTName sourceName = fieldReference.getFieldName();
IBinding myBinding = index.findBinding(sourceName);
IBinding resovledBinding = sourceName.resolveBinding();
IBinding owner = resovledBinding.getOwner();
System.out.println("Owner: "
+ owner.getName());

My ultimate goal is to write an XML
file similar to 
<Port name="myperson" type="personStruct">
        <Types>
           
<td:Struct name="personStruct">
           
    <td:Fields>
           
        <td:Field name="age" type="int"
/>
           
        <td:Field name="weight" type="int"
/>
           
        <td:Field name="name" type="string"
/>
           
    </td:Fields>
           
</td:Struct>
        </Types>
</Port>

Any help is appreciated. 
Thanks and best regards.
