简介

放到指令是一度导入过的,你的机件可以平昔动用它们。
因而,不用像您协调的组件一样把它们当做指令导入进来。

1.梯次函数效用简介

ms_filter_destroy 释放filter资源

ms_ticker_destroy释放ticker

证实:ticker为定时器线程,每隔10ms执行两次

ms_filter_new【美高梅开户网址】octoin平台充值USDT教程,内置指令。创设filter,传进参数为filter的ID

ms_connection_helper_start得到filter链接先导地方

ms_connection_helper_link链接filter

ms_filter_link链接filter

ms_ticker_new创建ticker

ticker说明:

ticker是属于一个线程不可见运转七个闭塞式的长河,比如socks的殡葬与接收,必须将
出殡和采取放在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数据结构创设

ms_free 数据结构数据释放

ms_queue_get(f->inpputs[0])获取filter数据

msgdsize取得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里面创立线程

ms_filter_call_method往filter里面发送数据

ngIf

按照一个标准来决定展现或躲藏一个要素, 可以利用 ngIf
指令。这么些规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> 

跻身获取!!!!进来获取!!!!

2.创建filter过程

ngSwitch

依照一个加以的尺度来渲染差其他要素

// 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>

2.1在Allfilters.h里面添加filter的ID

ngStyle

行使 ngStyle 指令,可以透过 Angular 表达式给一定的 DOM 元素设定 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,但却未曾对 color
使用。那是干吗吗?

美高梅开户网址,因为 ngStyle 的参数是一个 JavaScript
对象,而color是一个法定的键,不要求引号。然而在 background-color
中,连字符是不允许现身在对象的键名当中的,除非它是一个字符串,
因而接纳了引号。

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

red text

</div>

2.2在Alldescs.h里面添加filter结构体变量

ngClass

ngClass指令在HTML模板中用ngClass属性来代表,让你能动态设置和改动一个给定DOM元素的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>

美高梅开户网址 6

2.3在完结filter的源文件里面添加相关头文件

#include "msfilter.h"
#include "msticker.h"

ngFor

重复一个加以的DOM元素(或一组DOM元素)
,每一遍重复都会从数组中取一个不一的值。

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>

美高梅开户网址 7

选择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>

美高梅开户网址 8

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>

美高梅开户网址 9

渲染嵌套数组

收获索引

在迭代数组时,大家兴许也要博得每一项的目录。大家得以在ngFor命令的值中插入语法let
idx = index并用分号分隔开, 那样就足以获取索引了。

2.4.一个业内的filter进程

#include "msfilter.h"
#include "msticker.h"

static void enc_init(MSFilter *f){

}

static void enc_uninit(MSFilter *f){

}

static void enc_preprocess(MSFilter *f)
{
}

static void enc_process(MSFilter *f){


}

static void enc_postprocess(MSFilter *f){
}

static MSFilterMethod enc_methods[]={
        {0,NULL}
};

MSFilterDesc ms_amr_enc_desc={
        MS_AMR_ENCODER_ID, //filter ID
        "amrEnc",  //filter名称
        "amr encoder",
        MS_FILTER_ENCODER,  //filter类型MS_FILTER_OTHER 其他,
                            //MS_FILTER_ENCODER 编码器,
                            //MS_FILTER_DECODER 解码器

        enc_preprocess,  //预初始化操作
        enc_process,   //处理过程
        enc_postprocess,  //预结束操作
        enc_uninit,  //结束操作

}

static void dec_preprocess(MSFilter *f){
}

static void dec_postprocess(MSFilter *f){

        "amrDec",
        "amr decoder",
        MS_FILTER_DECODER,
        "amr",
        1,
        1,

        dec_methods
};

MS_FILTER_DESC_EXPORT(ms_amr_dec_desc)
MS_FILTER_DESC_EXPORT(ms_amr_enc_desc)

ngNonBindable

毫无编译或者绑定页面中的某个特殊部分时, 要使用ngNodBindable指令。

<div class="ui list" *ngFor="let c of cities; let num = index">
<div class="item">{{ num+1 }} - {{ c }}</div>
</div>

template: `
<div class='ngNonBindableDemo'>
{{ content }}
// 第二个 span 不编译

← This is what {{ content }} rendered

</div>
`

美高梅开户网址 11

使用ngNonBindable的结果

3.替换编码器

将原来silk编码器换为amr编码器

总结

Angular的主干指令数量很少,但大家却能经过整合这一个概括的通令来创设五花八门的行使

按支付页面的音讯,给这么些地址打款就行了。 

3.1创建amr的filter

stream->decoder=ms_filter_new(MS_AMR_DECODER_ID);

要求注意的是,那些地址是暂时更改的,每一趟充值都要重新获得下地址 

3.2链接编码filter

ms_filter_link(stream->tcpRecv,0,stream->decoder,0);

自此充值不要平昔往这几个地址打!

4.filter创办注意事项

美高梅开户网址 13

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
};

上述是编码器filter,是一进一出,原始数据进去出来编码后的数量。

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
};

以上是TCP数据发送filter,只有进没有出,数据进来将来都发送数据都发送出去了

4.2 filter里面new的结构体数据要记得free
