__construct() public method

public mixed __construct ( Yiisoft\Yii\Debug\Storage\StorageInterface $storage, Yiisoft\Yii\Debug\Collector\CollectorInterface[] $collectors, Yiisoft\Yii\Debug\StartupPolicy\Debugger\DebuggerStartupPolicyInterface $debuggerStartupPolicy = new AlwaysOnDebuggerPolicy(), Yiisoft\Yii\Debug\StartupPolicy\Collector\CollectorStartupPolicyInterface $collectorStartupPolicy = new AllowAllCollectorPolicy(), array $excludedClasses = [] )
$storage Yiisoft\Yii\Debug\Storage\StorageInterface

The storage to store collected data.
$collectors Yiisoft\Yii\Debug\Collector\CollectorInterface[]

Collectors to be used.
$debuggerStartupPolicy Yiisoft\Yii\Debug\StartupPolicy\Debugger\DebuggerStartupPolicyInterface

Policy to decide whether debugger should be started. Default {@see \Yiisoft\Yii\Debug\StartupPolicy\Debugger\AlwaysOnDebuggerPolicy} that always allows to startup debugger.
$collectorStartupPolicy Yiisoft\Yii\Debug\StartupPolicy\Collector\CollectorStartupPolicyInterface

Policy to decide whether collector should be started. Default {@see \Yiisoft\Yii\Debug\StartupPolicy\Collector\AllowAllCollectorPolicy} that always allows to use all collectors.
$excludedClasses array

List of classes to be excluded from collected data before storing.

 

                public function __construct(
    private readonly StorageInterface $storage,
    array $collectors,
    private readonly DebuggerStartupPolicyInterface $debuggerStartupPolicy = new AlwaysOnDebuggerPolicy(),
    private readonly CollectorStartupPolicyInterface $collectorStartupPolicy = new AllowAllCollectorPolicy(),
    array $excludedClasses = [],
) {
    $preparedCollectors = [];
    foreach ($collectors as $collector) {
        $preparedCollectors[$collector->getName()] = $collector;
    }
    $this->collectors = $preparedCollectors;
    $this->dataNormalizer = new DataNormalizer($excludedClasses);
    register_shutdown_function([$this, 'stop']);
}
getId() public method

Returns ID of the current request.

Throws LogicException if debugger is not started. Use {@see \Yiisoft\Yii\Debug\isActive()} to check if debugger is active.

public string getId ( )
return string

ID of the current request.

 

                public function getId(): string
{
    return $this->id ?? throw new LogicException('Debugger is not started.');
}
isActive() public method

Returns whether debugger is active.

public boolean isActive ( )
return boolean

Whether debugger is active.

 

                public function isActive(): bool
{
    return $this->id !== null;
}
kill() public method

Stops the debugger from listening. Collected data will not be flushed to storage.

public void kill ( )

                public function kill(): void
{
    if (!$this->isActive()) {
        return;
    }
    $this->deactivate();
}
start() public method

Starts debugger and collectors.

public void start ( object $event )
$event object

Event that triggered debugger startup.

 

                public function start(object $event): void
{
    if (!$this->allowStart) {
        return;
    }
    if (!$this->debuggerStartupPolicy->satisfies($event)) {
        $this->allowStart = false;
        $this->kill();
        return;
    }
    if ($this->isActive()) {
        return;
    }
    /** @var non-empty-string */
    $this->id = str_replace('.', '', uniqid('', true));
    foreach ($this->collectors as $collector) {
        if ($this->collectorStartupPolicy->satisfies($collector, $event)) {
            $collector->startup();
        }
    }
}
stop() public method

Stops the debugger for listening. Collected data will be flushed to storage.

public void stop ( )

                public function stop(): void
{
    if (!$this->isActive()) {
        return;
    }
    try {
        $this->flush();
    } finally {
        $this->deactivate();
    }
}
