[news.eclipse.tools.jdt] Change Signature Parameter Info

[wolfgang.schwaiger@xxxxxxxxx (Wolfgang Schwaiger)]

Hi Everybody,

Following situation; I have defined a ChangeMethodSignatureParticipant for 
the 'Change Method Signature' Refactoring operation. In the 
createChange(...) method of the participant I now need the information 
from the RefactoringProcessor what changes the user has entered in the UI. 
Eclipse itself uses for this a ChangeSignatureProcessor. Which in my case 
does not work, because the getProcessor() method only returns an instance 
of RefactoringProcessor.

The code at the moment looks as follows:

@Override
public Change createChange(IProgressMonitor pm) throws CoreException, 
OperationCanceledException {
   /*
   * Find out what operation was performed in the refactoring.
   */
   pm.subTask("Creating change results ...");
       
   ChangeSignatureProcessor processor = (ChangeSignatureProcessor) 
getProcessor();
       
   List parameterInfos = processor.getParameterInfos();
       
   for (Object object : parameterInfos) {
       ParameterInfo param = (ParameterInfo) object;
           
       System.out.println(param.getOldName());
       System.out.println(param.getNewName());
       System.out.println(param.isAdded());
       System.out.println(param.isRenamed());
       System.out.println(param.getOldIndex());
       System.out.println("------------------");
   }
}

So far so good. The problem is now, that ParameterInfo and 
ChangeSignatureProcessor are part of the package internal and so declared 
as Discouraged. The Syso's show exactly what I need. Does anybody has an 
idea how to get the parameter information without using Discouraged Access 
blocked classes? Or another way to find out which changes have to be done, 
e.g. param was added, param was removed, etc.

Thank you in advance for your help and thoughts.

Kind regards,
Wolfgang
