示例1: holder
bool
WatchpointMap::triggerWatchpoint(JSContext *cx, HandleObject obj, HandleId id, MutableHandleValue vp)
{
Map::Ptr p = map.lookup(WatchKey(obj, id));
if (!p || p->value.held)
return true;
AutoEntryHolder holder(cx, map, p);
/* Copy the entry, since GC would invalidate p. */
JSWatchPointHandler handler = p->value.handler;
RootedObject closure(cx, p->value.closure);
/* Determine the property's old value. */
Value old;
old.setUndefined();
if (obj->isNative()) {
if (RawShape shape = obj->nativeLookup(cx, id)) {
if (shape->hasSlot())
old = obj->nativeGetSlot(shape->slot());
}
}
// Read barrier to prevent an incorrectly gray closure from escaping the
// watchpoint. See the comment before UnmarkGrayChildren in gc/Marking.cpp
ExposeGCThingToActiveJS(closure, JSTRACE_OBJECT);
/* Call the handler. */
return handler(cx, obj, id, old, vp.address(), closure);
