ActionScheduler_ScheduleDeserializer::is_allowed_nested_class │ private │ WC 1.0

Decide whether a nested class (a property of the schedule) may be instantiated.

The only classes Action Scheduler itself ever nests inside a schedule are the bundled CronExpression family. Composite schedules that nest another schedule are also fine. The default list is filterable so extenders can vet their own supporting classes.

Method of the class: ActionScheduler_ScheduleDeserializer{}

No Hooks.

Returns

bool.

Usage

// private - for code of main (parent) class only
$result = $this->is_allowed_nested_class( $class_name, $allowed_nested ): bool;

$class_name(string) (required)

Class name discovered nested in the blob.

$allowed_nested(string[]) (required)

The resolved nested allow-list to check against.
