示例1: buildFuncSet
void CanRunScriptChecker::buildFuncSet(ASTContext *Context) {
// We create a match finder.
MatchFinder Finder;
// We create the callback which will be called when we find a function with
// a MOZ_CAN_RUN_SCRIPT annotation.
FuncSetCallback Callback(CanRunScriptFuncs);
// We add the matcher to the finder, linking it to our callback.
Finder.addMatcher(
functionDecl(hasCanRunScriptAnnotation()).bind("canRunScriptFunction"),
&Callback);
// We start the analysis, given the ASTContext our main checker is in.
Finder.matchAST(*Context);
