OHOSChannel

OHOSChannel is helper library for inter thread communication between main thread and worker thread.

Source

Inspired by skyfe79/AndroidChannel

Feature

This library is helper library for inter thread communication between main thread and worker thread. OHOSChannel uses EventHandler and EventRunner for inter thread communication.

Dependency

1. For using ohoschannel module in sample app, include the source code and add the below dependencies in entry/build.gradle to generate hap/support.har.

	dependencies {
		implementation project(path: ':ohoschannel')
                implementation fileTree(dir: 'libs', include: ['*.har'])
                testImplementation 'junit:junit:4.13'
	}

2. For using ohoschannel in separate application using har file, add the har file in the entry/libs folder and add the dependencies in entry/build.gradle file.

	dependencies {
		implementation fileTree(dir: 'libs', include: ['*.har'])
		testImplementation 'junit:junit:4.13'
	}

3. For using ohoschannel from a remote repository in separate application, add the below dependencies in entry/build.gradle file.

    dependencies {
        implementation 'dev.applibgroup:ohoschannel:1.0.0'  
        testCompile 'junit:junit:4.13'
    }

Usage

Ping-Pong

You can make a channel between main thread and worker thread easily.

channel = new OhosChannel(new OhosChannel.UiCallback() {
    @Override
    public boolean handleUiMessage(InnerEvent msg) {
        if (msg.eventId == PING) {
            HiLog.debug(HI_LOG_LABEL, " PING");
            ohosChannel.toWorker().sendEvent(PONG, 1000);
        }
        return false;
    }
}, new OhosChannel.WorkerCallback() {
    @Override
    public boolean handleWorkerMessage(InnerEvent msg) {
        if (msg.eventId == PONG) {
            HiLog.debug(HI_LOG_LABEL, " PONG");
            ohosChannel.toUi().sendEvent(PING, 1000);
        }
        return false;
    }
});
channel.toUi().sendEvent(PING);

Timer

If you use OHOSChannel, You can make Timer more easily. I already made Timer class for you. You can just use it. If you want to know how to implement Timer class, you just read source code in the package.

timer = new Timer(1000, new Timer.OnTimer() {
    int count = 0;
    @Override
    public void onTime(Timer timer) {
        count++;
        textView.setText("count : " + count);
    }
});
timer.start();	

You can also stop the timer like this.

@Override
public boolean onTouchEvent(TouchEvent event) {
    if (event.getAction() == TouchEvent.PRIMARY_POINT_UP) {
        if (timer.isAlive()) {
            timer.stop();
        } else {
            timer.start();
        }
    }
    return super.onTouchEvent(event);
}

APIs

• channel.open()
  • Use open() method to open channel. If you created a channel by Channel constructor, it is automatically open the channel by default.
• channel.close()
  • Use close() method to close channel. close() method removes callbacks and messages in the message queue.
• channel.toUi()
  • toUi() method returns main thread handler. If you want to send messages to ui thread you should use toUi() method.
• channel.toWorker()
  • toWorker() method returns worker thread handler. If you want to send messages to worker thread you should use toWorker() method.
