Public Properties ​
Property | Description |
---|---|
behaviors | yii\base\Behavior – List of behaviors attached to this component. |
db | craft\db\Connection, array, string – The database connection to use |
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 config4:softDeleteDuration config setting. |
probability | integer – The probability (parts per million) that garbage collection (GC) should be performed on a request. |
db
​
- Type
- craft\db\Connection, array, string
- Default value
'db'
- Since
- 4.0.0
The database connection to use
deleteAllTrashed
​
- Type
- boolean
- Default value
false
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 config4:softDeleteDuration config setting.
probability
​
- Type
- integer
- Default value
10
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.

deletePartialElements()
​
- Since
- 3.6.6
Deletes elements that are missing data in the given element extension table.
Arguments ​
$elementType
(string) – The element type$table
(string) – The extension table name$fk
(string) – The column name that contains the foreign key toelements.id
hardDelete()
​
Hard-deletes any rows in the given table(s), that are due for it.
Arguments ​
$tables
(string, string[]) – The table(s) to delete rows from. They must have adateDeleted

hardDeleteElements()
​
- Since
- 4.0.0
Hard-deletes eligible elements.
Any soft-deleted block elements which have revisions will be skipped, as their revisions may still be needed by the owner element.
hardDeleteVolumes()
​
Hard delete eligible volumes, deleting the folders one by one to avoid nested dependency errors.
init()
​
Initializes the object.
This method is invoked at the end of the constructor after the object is initialized with the given configuration.
removeEmptyTempFolders()
​
- Since
- 4.0.0
Find all temp upload folders with no assets in them and remove them.
Throws ​
run()
​
Possibly runs garbage collection.
Arguments ​

(boolean) – Whether garbage collection should be forced. If left asfalse
, then garbage collection will only run if a random condition passes, factoring in probability.
Events ​
EVENT_RUN ​
- Type
craft\services\Event
