Angular 2 - Composer Library

注意：您可以创建自己的组件，这些组件是为您的应用程序定制的。 Composer 完成所有繁重的工作，为应用程序集成提供最大的灵活性。

Directives

Binding

binding 属性可以附加到任何元素以管理设备属性的数据。

Name	Binding	Direction	Valid Types	Description
value	Two-way	Read & Write	String	Value of the bound. Updates when servers value is changed.
sys	One-way	Write-only	String	Identifier of the system to connect
mod	One-way	Write-only	String	Identifier of the module in the system to use e.g. Display
index	One-way	Write-only	Number	Index of the module in the system. Default: 1
bind	One-way	Write-only	String	Name of the variable in module to bind
exec	One-way	Write-only	String	Name of the function to execute on the server when the binding value changes. If undefined no function call will occur. If defined as empty function name will be bind value
params	One-way	Write-only	Any[]	Array parameters to pass into the function on the server. Defaults to value

Debug

debug 属性可以附加到任何元素以获取日志信息所选设备。

< /div>

Name	Binding	Direction	Valid Types	Description
output	Two-way	Read & Write	String	Array of Debugging messsages on set module
sys	One-way	Write-only	String	Identifier of the system to connect
mod	One-way	Write-only	String	Identifier of the module in the system to use e.g. Display
index	One-way	Write-only	Number	Index of the module in the system. Default: 1
enable	One-way	Write-only	String	Enables debugging. Output will not update if false

Services

System Service

系统服务执行绑定上的所有交互。

通过此服务设置身份验证详细信息。

Resources Service

资源服务用于使访问 Control API 变得简单。

Usage in Web Workers

在 web worker 中运行 Angular 2 会限制对某些全局范围变量的访问。 由于 auth 需要本地和会话存储才能正常运行，因此您需要在您的应用程序中注册一个 Message Broker，以便 auth 可以运行。

下面给出了如何注册此消息代理的示例。

import {WORKER_UI_LOCATION_PROVIDERS, bootstrapWorkerUi} from '@angular/platform-webworker';
import { DataStoreBroker } from '@aca-1/a2-composer';

bootstrapWorkerUi('webworker.bundle.js', WORKER_UI_LOCATION_PROVIDERS).then((ref) => {
    let broker = new DataStoreBroker(ref);
});

您还需要将 DataStoreWorkerService 添加到根模块，以便工作人员与代理进行通信。

import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { RouterModule } from '@angular/router';
import { WorkerAppModule, WORKER_APP_LOCATION_PROVIDERS } from '@angular/platform-webworker';
import { ACA_COMPOSER_MODULE, DataStoreService, DataStoreWorkerService } from '@acaprojects/a2-composer';

@NgModule({
  bootstrap: [ AppComponent ],
  declarations: [
      ...
  ],
  imports: [
    WorkerAppModule,
    FormsModule,
    HttpModule,
    RouterModule.forRoot(ROUTES, { useHash: true }),
    ACA_COMPOSER_MODULE
  ],
  providers: [
    ...
    WORKER_APP_LOCATION_PROVIDERS,
    { provide: DataStoreService, useClass: DataStoreWorkerService }
  ]
})
export class AppModule {

}
