我有一个像这样的c代码int x; x = 5;
我使用eclipse cdt生成AST，并在其上遍历，因此这是被遍历类的代码

public class RuleChk extends AbstractRule {
    public RuleChk(IASTTranslationUnit ast) {
        super("RuleChk", false, ast);
        shouldVisitDeclarations = true;
        shouldVisitParameterDeclarations = true;
    }

    @Override
    public int visit(IASTSimpleDeclaration simpleDecl) {
        //if this node has init, e.g: x = 5, do business
        if(VisitorUtil.containNode(simpleDecl, CASTExpressionStatement){
           // Now I have the x = 5 node, 
           // I want to get the reference node of it's declaration
           // I mean (int x;) node
           IASTNode declNode = ?????
        }
        return super.visit(parameterDeclaration);
    }
}

字符串
我想访问的节点只有assignation（赋值），并获得该变量的声明节点的引用。
