示例1: if
/// Try to capture an implicit reference to 'self'.
ObjCMethodDecl *Sema::tryCaptureObjCSelf() {
// Ignore block scopes: we can capture through them.
DeclContext *DC = CurContext;
while (true) {
if (isa<BlockDecl>(DC)) DC = cast<BlockDecl>(DC)->getDeclContext();
else if (isa<EnumDecl>(DC)) DC = cast<EnumDecl>(DC)->getDeclContext();
else break;
}
// If we're not in an ObjC method, error out. Note that, unlike the
// C++ case, we don't require an instance method --- class methods
// still have a 'self', and we really do still need to capture it!
ObjCMethodDecl *method = dyn_cast<ObjCMethodDecl>(DC);
if (!method)
return 0;
ImplicitParamDecl *self = method->getSelfDecl();
assert(self && "capturing 'self' in non-definition?");
// Mark that we're closing on 'this' in all the block scopes, if applicable.
