说明你没添加进来 ,进来获取

进来获取,如果找不到USDT这个币种,USDT,发送和接收放在filter线程里面,ticker为定时器线程,使用索引,渲染嵌套数组,第三就是Video Speed Controller,他为什么能实现加速呢

4.filter创制注意事项

ngSwitch

基于一个加以的条件来渲染不一致的成分

// ngSwitchCase 指令描述已知结果;
// ngSwitchDefault 指令处理所有其他未知情况
// ngSwitchDefault 元素是可选的。如果我们不用它,
// 那么当 myVar 没有匹配到任何期望的值时就不会渲染任何东西
<div class="container" [ngSwitch]="myVar">
<div *ngSwitchCase="'A'">Var is A</div>
<div ngSwitchCase="'B'">Var is B</div>
<div ngSwitchDefault>Var is something else</div>
</div>

// 想要处理新值 C, 只需要插入一行
<div class="container" [ngSwitch]="myVar">
<div *ngSwitchCase="'A'">Var is A</div>
// 会渲染两次
<div *ngSwitchCase="'A'">Var is A</div>
<div ngSwitchCase="'B'">Var is B</div>
<div ngSwitchCase="'C'">Var is C</div>
<div *ngSwitchDefault>Var is something else</div>
</div>

前天大家看一下怎么获取增添程序,点这里有越多工具扩大程序拉到最下边点击的获得更加多的恢弘程序弄只要在那地追寻就行了,他怎么可以促成加快呢,因为这里这一个帮手,它能帮大家替换到HTML5播放器,然后这里Video
Speed Controller,

简介

放置指令是现已导入过的,你的组件能够一直利用它们。
由此,不用像你和谐的零件同样把它们作为指令导入进来。

1.挨门逐户函数效能简单介绍

ms_filter_destroy 释放filter资源

ms_ticker_destroy释放ticker

证实:ticker为反应计时器线程,每间距10ms试行一遍

ms_filter_new创办filter,传进参数为filter的ID

ms_connection_helper_start获得filter链接发轫地方

ms_connection_helper_link链接filter

ms_filter_link链接filter

ms_ticker_new创建ticker

ticker说明:

ticker是属于二个线程不可见运行多少个闭塞式的历程,比如socks的出殡和安葬与摄取,必需将
出殡和收受放在filter线程里面。

ms_ticker_set_name设置ticker名称

ms_ticker_attach将ticker附加到线程中

ms_ticker_detach去掉ticker

ms_connection_helper_unlink去掉filter链接

ms_filter_unlink 去掉filter链接

ms_new filter数据结构创制

ms_free 数据结构数据释放

ms_queue_get(f->inpputs[0])获取filter数据

msgdsize获得filter里面数据长度

ms_queue_put(f->outputs[0],om)往filter里面塞数据

freemsg释放filter数据

ms_thread_join在filter里面创制线程

ms_filter_call_method往filter里面发送数据

ngIf

依照五个标准来决定展现或回避三个成分, 能够采取 ngIf
指令。这么些原则是由你传给指令的表明式的结果决定的

<div ngIf="false"></div> 
<div ngIf="a > b"></div> 
<div ngIf="str == 'yes'"></div> 
<div ngIf="myFunc()"></div> 

摄像地址

进去获取!!!!进来获取!!!!

4.2 filter里面new的结构体数据要记得free

ngFor

再次多少个加以的DOM元素(或风流倜傥组DOM成分)
,每一趟重复都会从数组中取五个不黄金时代的值。

this.cities = ['Miami', 'Sao Paulo', 'New York'];

<h4 class="ui horizontal divider header">
Simple list of strings
</h4>
<div class="ui list" *ngFor="let c of cities">
<div class="item">{{ c }}</div>
</div>

图片 7

应用ngFor指令的结果

// 根据每一行数据渲染出一个表格
this.people = [
    { name: 'Anderson', age: 35, city: 'Sao Paulo' },
    { name: 'John', age: 12, city: 'Miami' },
    { name: 'Peter', age: 22, city: 'New York' }
];

<h4 class="ui horizontal divider header">
    List of objects
</h4>
<table class="ui celled table">
    <thead>
        <tr>
            <th>Name</th>
            <th>Age</th>
            <th>City</th>
        </tr>
    </thead>
    <tr *ngFor="let p of people">
        <td>{{ p.name }}</td>
        <td>{{ p.age }}</td>
        <td>{{ p.city }}</td>
    </tr>
</table>

渲染对象数组

// 使用嵌套数组
this.peopleByCity = [
    {   city: 'Miami',
        people: [
            { name: 'John', age: 12 },
            { name: 'Angel', age: 22 }
        ]
    },
    {   city: 'Sao Paulo',
        people: [
            { name: 'Anderson', age: 35 },
            { name: 'Felipe', age: 36 }
        ]
    }
]

<h4 class="ui horizontal divider header">
    Nested data
</h4>
<div ngFor="let item of peopleByCity">
    <h2 class="ui header">{{ item.city }}</h2>
    <table class="ui celled table">
        <thead>
            <tr>
                <th>Name</th>
                <th>Age</th>
            </tr>
        </thead>
        <tr ngFor="let p of item.people">
            <td>{{ p.name }}</td>
            <td>{{ p.age }}</td>
        </tr>
    </table>
</div>

渲染嵌套数组

取得索引

在迭代数组时,大家恐怕也要赢得每风姿浪漫项的目录。我们能够在ngFor命令的值中插入语法let
idx = index并用分号分隔开分离, 那样就足以收获索引了。

选用索引

世家看那一个进度条也看到她快了吗。

2.2在Alldescs.h里面增添filter结构体变量

ngStyle

应用 ngStyle 指令,可以透过 Angular 说明式给一定的 DOM 成分设定 CSS
属性。

// 简单用法
<div [style.background-color]="'yellow'">
Uses fixed yellow background
</div>

<div [ngStyle]="{color: 'white', 'background-color': 'blue'}">
Uses fixed white text on blue background
</div>

对 background-color 使用了单引号,但却还没对 color
使用。那是干什么呢?

因为 ngStyle 的参数是一个 JavaScript
对象,而color是二个法定的键,无需引号。不过在 background-color
中,连字符是不容许出未来目的的键名个中的,除非它是多少个字符串,
由此利用了引号。

// 设置文字大小
//1. style.font-size.px
//2. style.font-size.em
//3. style.font-size.%
<div>

red text

</div>

亟待注意的是,那些地点是临时转移的,每便充钱都要重复赢得下地址 

4.1 filter里面数据流要对应

MSFilterDesc ms_amr_dec_desc={
        MS_AMR_DECODER_ID,
        "amrDec",
        "amr decoder",
        MS_FILTER_DECODER,
        "amr",
        1,  //进
        1,  //出
        dec_init,
        dec_preprocess,
        dec_process,
        dec_postprocess,
        dec_uninit,
        dec_methods
};

如上是编码器filter,是生机勃勃进后生可畏出,原始数据进去出来编码后的数目。

MSFilterDesc ms_tcpclient_send_desc={
        MS_TCP_SEND_ID,
        "TcpClientSend",
        "TcpClient_Send",
        MS_FILTER_OTHER,
        "tcpclient",
        1,  //进
        0,  //出
        tcp_send_init,
        tcp_send_preprocess,
        tcp_send_process,
        tcp_send_postprocess,
        tcp_send_uninit,
        tcpclient_send_methods
};

如上是TCP数据发送filter,唯有进未有出,数据进来现在都发送数据都发送出去了

ngClass

ngClass指令在HTML模板中用ngClass属性来代表,令你能动态设置和转移八个给定DOM成分的CSS类

.bordered {
border: 1px dashed black;
background-color: #eee;
}
// 简单用法
<div [ngClass]="{bordered: false}">This is never bordered</div>
<div [ngClass]="{bordered: true}">This is always bordered</div>
