Description

for (Attribute attribute : method.getAttributes()) {
    if (attribute instanceof Signature) {
        Signature sig = (Signature) attribute;
        System.out.println("Sig: " + sig.getSignature());
        System.out.println("Ret: " + Type.getReturnType(sig.getSignature()));
        System.out.println("Prm: " + Type.getArgumentTypes(sig.getSignature()));
    }
}

Input:     public SampleReturn<SampleMethodReturnType> 
           method
             (SampleMethodParameter<SampleMethodParameterType> param1) {
              ...
           }

Output:

Ret: net.sf.sample.SampleReturn<Lnet.sf.sample.SampleMethodReturnType
