public yii\queue\db\Queue $queue = null

Method Details

actionClear() public method (available since version 2.0.1)

Clears the queue.

public void actionClear ( )

actionListen() public method

Listens db-queue and runs new jobs.

It can be used as daemon process.

public null\|integer actionListen ( $timeout = 3 )
$timeout	integer	Number of seconds to sleep before next reading of the queue.
return	null\|integer	Exit code.
throws	yii\console\Exception	when params are invalid.

actionRemove() public method (available since version 2.0.1)

Removes a job by id.

public void actionRemove ( $id )
$id	integer
throws	yii\console\Exception	when the job is not found.

actionRun() public method

Runs all jobs from db-queue.

It can be used as cron job.

public null\|integer actionRun ( )
return	null\|integer	Exit code.

actions() public method

Declares external actions for the controller.

This method is meant to be overwritten to declare external actions for the controller. It should return an array, with array keys being action IDs, and array values the corresponding action class names or action configuration arrays. For example,

return [
    'action1' => 'app\components\Action1',
    'action2' => [
        'class' => 'app\components\Action2',
        'property1' => 'value1',
        'property2' => 'value2',
    ],
];

Yii::createObject() will be used later to create the requested action using the configuration provided here.

public array actions ( )

isWorkerAction() protected method (available since version 2.0.2)

protected boolean isWorkerAction ( $actionID )
$actionID	string
