示例1: findJavaRefs

private static List<JsniJavaRef> findJavaRefs(
final MethodDeclaration jsniMethod) throws IOException,
JavaScriptParseException, BadLocationException {

ICompilationUnit cu = JavaASTUtils.getCompilationUnit(jsniMethod);
final IPath cuPath = cu.getResource().getFullPath();
final List<JsniJavaRef> javaRefs = new ArrayList<JsniJavaRef>();
JsBlock js = JsniParser.parse(jsniSource);
if (js != null) {
// Visit the JavaScript AST to find all Java references
new JsVisitor() {
@Override

JsniJavaRef javaRef = JsniJavaRef.parse(ident);
if (javaRef != null) {
// Set the reference's Java source file
javaRef.setSource(cuPath);
// To get the Java reference offset, we have to do an indexOf on
// its identifier. To make sure we catch multiple references to
// the same Java element, we need to start at the index one past
// the start of the last Java reference we found (if any)
int fromIndex = 0;
if (javaRefs.size() > 0) {
fromIndex = javaRefs.get(javaRefs.size() - 1).getOffset()
- jsniMethod.getStartPosition() + 1;

// Set the reference's offset within the Java source file
javaRef.setOffset(offset);
