Re: [cdt-dev] C Structure fields analysis

[Adrien G <adrien_chem@xxxxxxxxxxx>]

Thank you Marco, that helped me a lot.

Also another question, lets say I have that struct :

struct CINEMATIC

{

    T_GeodeticLocation location;

    T_Attitude attitude;

    T_SpeedVector speed;

    char text[50];

    double yaw;

    T_SpeedVector speeds[20];

    QString toto;

    quint64 test_int;

    char* forbidden;

};

For each member I want to know the name, the type, if it is an array (in that case the size) and if it is a pointer.

But I don't see how to retrieve those informations from a CASTSimpleDeclaration instance.

public int visit(IASTDeclaration node)

{

if(node instanceof CASTSimpleDeclaration)

{

CASTSimpleDeclaration cnode = (CASTSimpleDeclaration) node;

System.out.println("instanceof CASTSimpleDeclaration");

IASTCompositeTypeSpecifier struct = (IASTCompositeTypeSpecifier)cnode.getDeclSpecifier();

if(struct.getKey() == IASTCompositeTypeSpecifier.k_struct)

{

System.out.println("struct_name=" + struct.getName());

IASTDeclaration[] members = struct.getMembers();

for (IASTDeclaration member : members)

{

if(member instanceof CASTSimpleDeclaration)

{

CASTSimpleDeclaration cmember = (CASTSimpleDeclaration) member;

try {

System.out.print("member_spec=" + cmember.getDeclSpecifier().getSyntax().toString());

} catch (ExpansionOverlapsBoundaryException e) {

e.printStackTrace();

}

for (IASTDeclarator declarator : cmember.getDeclarators())

{

System.out.println("    member_name=" + declarator.getName());

}

}

}

}

}

return PROCESS_SKIP; // Tell the visitor to not visit children nodes.

}

Thanks for your advise :)
