Situation. I have some type A1 that uses type B1. When user renames
A1 to A2, my rename participant should rename B1 to B2. However my
B1->B2 rename modifies also A1 (renamed to A2), so I see following
exception:
org.eclipse.text.edits.MalformedTreeException: End position lies outside
document range
at
org.eclipse.text.edits.TextEditProcessor.checkIntegrityDo(Te xtEditProcessor.java:169)
I've read in documentation that in 3.1 it is possible to change same
text file in participant and getTextChange() should be used. However I
don't understand how I should use it. I don't see any example of its
invocation in Eclipse itself. :-(
So, is it possible at all? Can you give me example or point where I
can get example?
To rename type B2 I use following method:
private static Change createTypeRenameChange(IType type, String
newName, IProgressMonitor pm) throws CoreException {
JavaRenameProcessor renameProcessor = new RenameTypeProcessor(type);
renameProcessor.setNewElementName(newName);
//
RenameRefactoring renameRefactoring = new
RenameRefactoring(renameProcessor);
RefactoringStatus status = renameRefactoring.checkAllConditions(pm);
if (status.hasError()) {
System.out.println("Hm...");
}
//
return renameRefactoring.createChange(pm);
}
May be problem with this method?
