如何创建新的 SpanGenerators

每个 SpanGenerator 都必须在 APM 代理上注册 processSpan() 方法，以便捕获我们想要的事件。

public static function register(ContainerBuilder $containerBuilder, ServiceDefinition $apmTransaction): void
{
    // Some code ...
    $service->addSetup('
        $service->onEventStart[] = function ($param1, $param2) :void {
            (?)->processSpan(?, ?, $param1, $param2);
        }', [$apmTransaction, self::class, 'start']);
    $service->addSetup('
        $service->onEventEnd[] = function ($param1, $param2) :void {
            (?)->processSpan(?, ?, $param1, $param2);
        }', [$apmTransaction, self::class, 'end']);
}

public function process(float $transactionStart, string $method, array $params): array
{
    switch($method) {
        case 'start':
            // do something ...
            return $spans; // array with spans
        case 'end':
            // do something else ...
            return $spans; // array with spans
    }
}
