callback逻辑疑问

[walkertest]

TarsCodec.decodeCallbackArgs 方法中

    public Object[] decodeCallbackArgs(TarsServantResponse response) throws ProtocolException {
        byte[] data = response.getInputStream().read(new byte[]{}, 6, true);
        TarsServantRequest request = response.getRequest();

        TarsMethodInfo methodInfo = null;
        Map<Method, TarsMethodInfo> map = AnalystManager.getInstance().getMethodMap(request.getApi());
        for (Iterator<Map.Entry<Method, TarsMethodInfo>> it = map.entrySet().iterator(); it.hasNext(); ) {
            Map.Entry<Method, TarsMethodInfo> entry = it.next();
            if (entry.getKey().getName().equals(request.getFunctionName())) {
                methodInfo = entry.getValue();
            }
        }

        try {
            return decodeCallbackArgs(data, response.getCharsetName(), methodInfo);
        } catch (Exception e) {
            throw new ProtocolException(e);
        }
    }

TarsMethodInfo 的获取为什么要注册容器中获取，并且只匹配了方法名，如果有同名方法，可能会有问题.
