将C ++代码从结构迁移到类(migrating C++ code from structures to classes)

我正在将一些C ++代码从结构迁移到类。

我使用的结构主要用于位域优化,我不再需要它了(我现在比节省空间更担心速度)。

  • 做这个迁移的一般准则是什么? 我仍然处于规划阶段,因为这是影响大部分代码的重大举措。 在做之前我想先计划一切。 我应该牢记的是什么?

I am migrating some C++ code from structures to classes.

I was using structures mainly for bit-field optimizations which I do not need any more (I am more worried about speed than saving space now).

  • What are the general guidelines for doing this migration? I am still in the planning stage as this is a very big move affecting a major part of the code. I want to plan everything first before doing it. What are all the essential things I should keep in mind?

错误说:Sonata \ MediaBundle \ Admin \ BaseMediaAdmin :: __ construct()中不存在参数5

所以,看一下sonata.media.admin.media服务配置中的参数。 只有4个参数。 你需要添加第5个。

在bundle config( https://github.com/sonata-project/SonataMediaBundle/blob/master/Resources/config/doctrine_orm_admin.xml )中,有5个参数:

<argument/>
<argument>%sonata.media.admin.media.entity%</argument>
<argument>%sonata.media.admin.media.controller%</argument>
<argument type="service" id="sonata.media.pool"/>
<argument type="service" id="sonata.media.manager.category" on-invalid="null"/>

所以,我认为你可以添加@ sonata.media.manager.category作为第五个参数。


The error say : Argument 5 doesn't exist in Sonata\MediaBundle\Admin\BaseMediaAdmin::__construct()

So, look at arguments in you sonata.media.admin.media service configuration. There are only 4 arguments. You need to add the 5th.

In bundle config (https://github.com/sonata-project/SonataMediaBundle/blob/master/Resources/config/doctrine_orm_admin.xml), there are 5 arguments :

<argument/>
<argument>%sonata.media.admin.media.entity%</argument>
<argument>%sonata.media.admin.media.controller%</argument>
<argument type="service" id="sonata.media.pool"/>
<argument type="service" id="sonata.media.manager.category" on-invalid="null"/>

So, I think you can add @sonata.media.manager.category as 5th argument.
