An interface to report and relay arbitrary messages to registered handlers. This was part of the Semantic MediaWiki code base and is now being deployed as independent library.

Requirements

PHP 5.6.99 or later

Installation

The recommended installation method for this library is to add it as dependency to your composer.json.

{
	"require": {
		"onoi/message-reporter": "~1.3"
	}
}

Usage

The message reporter specifies MessageReporter and MessageReporterAware as an interface for all interactions with a set of supporting classes:

  • MessageReporterFactory
  • ObservableMessageReporter
  • NullMessageReporter
  • SpyMessageReporter
  • CallbackMessageReporter
use Onoi\MessageReporter\MessageReporterFactory;
use Onoi\MessageReporter\MessageReporterAware;
use Onoi\MessageReporter\MessageReporterAwareTrait;
use Onoi\MessageReporter\MessageReporter;

class Bar implements MessageReporterAware {

	use MessageReporterAwareTrait;

	public function __construct() {
		$this->messageReporter = MessageReporterFactory::getInstance()->newNullMessageReporter();
	}

	public function doSomething() {
		$this->messageReporter->reportMessage( 'Doing ...' );
	}
}
use Onoi\MessageReporter\MessageReporterFactory;
use Onoi\MessageReporter\MessageReporter;

class Foo implements MessageReporter {

	public function reportMessage( $message ) {
		// output
	}
}

$foo = new Foo();

$messageReporterFactory = new MessageReporterFactory();

$observableMessageReporter = $messageReporterFactory->newObservableMessageReporter();
$observableMessageReporter->registerReporterCallback( array( $foo, 'reportMessage' ) );

or

// If the class implements the MessageReporter
$observableMessageReporter->registerMessageReporter( $foo );

$bar = new Bar();
$bar->setMessageReporter( $observableMessageReporter );
