Public Properties
| Property | Description |
|---|---|
| $behaviors | yii\base\Behavior – List of behaviors attached to this component |
| $deleteAllTrashed | boolean – Whether hardDelete() should delete all soft-deleted rows, rather than just the ones that were deleted long enough ago to be ready for hard-deletion per the craft\config\GeneralConfig::$softDeleteDuration config setting. |
| $probability | integer – The probability (parts per million) that garbage collection (GC) should be performed on a request. |
$deleteAllTrashed
- Type
- boolean
Whether hardDelete() should delete all soft-deleted rows, rather than just the ones that were deleted long enough ago to be ready for hard-deletion per the craft\config\GeneralConfig::$softDeleteDuration config setting.
Signature
public boolean $deleteAllTrashed = false
$probability
- Type
- integer
The probability (parts per million) that garbage collection (GC) should be performed on a request. Defaults to 10, meaning 0.001% chance.
This number should be between 0 and 1000000. A value 0 means no GC will be performed at all unless forced.
Signature
public integer $probability = 10

hardDelete()
Hard-deletes any rows in the given table(s), that are due for it.
Arguments
Signature
public void hardDelete ( $tables )
run()
Possibly runs garbage collection.
Arguments
$force(boolean) – Whether garbage collection should be forced. If left asfalse, then garbage collection will only run if a random condition passes, factoring in $probability.
Signature
public void run ( \craft\services\bool $force = false )
Events
EVENT_RUN
- Type
\craft\services\Event
The event that is triggered when running garbage collection.
