WorkflowPublishTargetJob

Extensions can have a construct but don't have too.

Without a construct, it's impossible to create a job in the CMS

Return a signature for this queued job

By default jobs should just go into the default processing queue

Specifies what user ID should be when running the job valid values: null - (default) - run the job as current user 0 - run the job without a user greater than zero - run the job as a specific user

This is useful in situations like:

• a job needs to always run without a user (like a static cache job)
• a job needs to run as a specific user (for example data migration job)

Note that this value can be overridden in the see QueuedJobService::queueJob()

Performs setup tasks the first time this job is run.

This is only executed once for every job. If you want to run something on every job restart, use the {@link prepareForRestart} method.

Run when an already setup job is being restarted.

Do some processing yourself!

Method for determining whether the job is finished - you may override it if there's more to it than just this

Called when the job is determined to be 'complete'

Gets custom config settings to use when running the job.

Sets custom config settings to use when the job is run.

Convenience methods for setting and getting job data

Retrieve some job data

Attempts to locate and call a method dynamically added to a class at runtime if a default cannot be located

You can add extra methods to a class using {@link Extensions}, {@link Object::createMethod()} or {@link Object::addWrapperMethod()}

Return TRUE if a method exists on this object

This should be used rather than PHP's inbuild method_exists() as it takes into account methods added via extensions

Return the names of all the methods available on this object

Add an extension to a specific class.

The preferred method for adding extensions is through YAML config, since it avoids autoloading the class, and is easier to override in more specific configurations.

As an alternative, extensions can be added to a specific class directly in the {@link Object::$extensions} array. See {@link SiteTree::$extensions} for examples. Keep in mind that the extension will only be applied to new instances, not existing ones (including all instances created through {@link singleton()}).

Remove an extension from a class.

Note: This will not remove extensions from parent classes, and must be called directly on the class assigned the extension.

Keep in mind that this won't revert any datamodel additions of the extension at runtime, unless its used before the schema building kicks in (in your _config.php). Doesn't remove the extension from any {@link Object} instances which are already created, but will have an effect on new extensions. Clears any previously created singletons through {@link singleton()} to avoid side-effects from stale extension information.

Get extra config sources for this class

Return TRUE if a class has a specified extension.

This supports backwards-compatible format (static Object::has_extension($requiredExtension)) and new format ($object->has_extension($class, $requiredExtension))

Calls a method if available on both this object and all applied {@link Extensions}, and then attempts to merge all results into an array

Run the given function on all of this object's extensions. Note that this method originally returned void, so if you wanted to return results, you're hosed

Currently returns an array, with an index resulting every time the function is called. Only adds returns if they're not NULL, to avoid bogus results from methods just defined on the parent extension. This is important for permission-checks through extend, as they use min() to determine if any of the returns is FALSE. As min() doesn't do type checking, an included NULL return would fail the permission checks.

The extension methods are defined during {@link __construct()} in {@link defineMethods()}.

Get an extension instance attached to this object by name.

Returns TRUE if this object instance has a specific extension applied in {@link $extension_instances}. Extension instances are initialized at constructor time, meaning if you use {@link add_extension()} afterwards, the added extension will just be added to new instances of the extended class. Use the static method {@link has_extension()} to check if a class (not an instance) has a specific extension.

Caution: Don't use singleton()->hasExtension() as it will give you inconsistent results based on when the singleton was first accessed.

Get all extension instances for this specific object instance.

See {@link get_extensions()} to get all applied extension classes for this class (not the instance).

This method also provides lazy-population of the extension_instances property.
