Greetings,

We’re working on an app, and the developer is including the xmlpull library to work with some XML data.

In XCode, the XmlPullParserFactory.mm class shows a pair of Semantic issues with a specific line.

In the original java it looks like this:

final String name = classNames.substring(pos, cut);

Class candidate = null;

Object instance = null;

try

{

  candidate = Class.forName(name);

// necessary because of J2ME .class issue

instance = candidate.newInstance();

}

When converted to Objective C, the first line in the try block looks like:

candidate = Class::forName(name);

… and I get the following 2 issues with that line:

•   Expected a class or namespace
  

•   Reference to ‘Class’ is ambiguous
  

I’ve done no native iOS development, so I don’t know where to start on this. Has anyone seen anything like this before, or have any insight they can share?

Ambiguity sometimes happens where ObjectiveC names clash with Java ones.

I would modify the java to have an import at the top of:

import java.lang.Class;

and then change any references to Class to be fully qualified e.g.

java.lang.Class candidate = null;

…

        candidate = java.lang.Class.forName(name);

etc…

That way the compiler will not have a chance to get confused.

Cheers,

Matt
