Re: [cdt-dev] Eclipse CDT - Get the definition of a C++ method when I ha

[Lukas Felber <lfelber@xxxxxx>]

Hi Sonia

To solve your problem, I think that you have to use the Indexer and
AST-Structure provided by CDT. I try to give you some hints in the
following (incomplete) code:


IIndex index = CCorePlugin.getIndexManager().getIndex(project);
// you should lock and unlock the index before and after use
int astStyle = ITranslationUnit.AST_CONFIGURE_USING_SOURCE_CONTEXT |
ITranslationUnit.AST_SKIP_INDEXED_HEADERS;
IASTTranslationUnit astTu = translationUnit.getAST(index, astStyle);
//use a CPPASTVisitor (you have to subclass it) to find classes
//(which in the ast are ICPPASTCompositeTypeSpecifier)
//to find class source code use
compTypeSpecifier.getRawSignature();
//to find its methods use
ICPPClassType classBinding = (ICPPClassType)
compTypeSpecifier.resolveBinding();
classBinding.getMethods();
index.findNames(x, IIndex.FIND_DEFINITIONS);
//this gives you the IName of the method definition.
//you should be able to use the name's IASTFileLocation to get
//information about the whereabout of the method's definition

I hope this information helps you to solve your problem.
