Function validateHandlerTarget

lib/bridge.js:447–450

(handler, target)

	// Throws VMError(OPNA) on either, the same error used elsewhere for
	// boundary violations, so attackers learn nothing about internal state.
	function validateHandlerTarget(handler, target) {
		if (!thisReflectApply(thisWeakMapHas, handlerToTarget, [handler])) throw new VMError(OPNA);
		if (thisReflectApply(thisWeakMapGet, handlerToTarget, [handler]) !== target) throw new VMError(OPNA);
	}

	// Closure-scoped function to retrieve the factory from a handler.
	// This is NOT a method on BaseHandler, so it cannot be called by attackers
