What does clang::ObjCPropertyDecl::getPropertyAttributes() really gets?

Hi all,

I’m trying to extract all attributes from an ObjCPropertyDecl such as:

@property (strong, nonatomic) NSMutableDictionary* fieldsToBePosted;

So I refered to the clang docs and found the function clang::ObjCPropertyDecl::getPropertyAttributes(), which looks like what I need. Then I wrote a piece of code like this:

clang::ObjCPropertyDecl::PropertyAttributeKind kind = decl->getPropertyAttributes();

cout << kind << endl;

What surprised me is that I got 64 (0x40), which is OBJC_PR_nonatomic. What I expected is OBJC_PR_nonatomic | OBJC_PR_strong a.k.a. 1088(0x440).

Also, as I tried to dump the decl, it looks like this:


ObjCPropertyDecl 0x7fc9ac66c640 </Users/wzpan/Documents/workspace/HelloWorld/HelloWorldViewController.m:14:1, col:52> col:52 fieldsToBePosted 'NSMutableDictionary *' nonatomic

Where has the strong attributes gone? Can anyone please tell me how to get all the attributes? Thanks.

Try: getPropertyAttributesAsWritten
