Temporarily modify the owner. The original owner is ensured to be restored

Clear the current owner, and restore extension to the state prior to the last setOwner()

Returns the owner of this extension.

Helper method to strip eval'ed arguments from a string that's passed to {@link DataObject::$extensions} or {@link Object::add_extension()}.

Invoke extension point. This will prefer explicit extend prefixed methods.

Hook for extension-specific validation.

Update any requests to limit the results to the current site

Update the database schema as required by this extension.

When duplicating a table's structure, remember to duplicate the create options as well. See {@link Versioned->augmentDatabase} for an example.

Augment a write-record request.

Extend the owner's onBeforeWrite() logic

See {@link DataObject::onBeforeWrite()} for context.

Extend the owner's onAfterWrite() logic

See {@link DataObject::onAfterWrite()} for context.

Extend the owner's onBeforeDelete() logic

See {@link DataObject::onBeforeDelete()} for context.

Extend the owner's onAfterDelete() logic

See {@link DataObject::onAfterDelete()} for context.

Extend the owner's requireDefaultRecords() logic

See {@link DataObject::requireDefaultRecords()} for context.

Extend the owner's populateDefaults() logic

See {@link DataObject::populateDefaults()} for context.

Extend the owner's onAfterBuild() logic

See {@link DataObject::onAfterBuild()} for context.

Influence the owner's can() permission check value to be disallowed (false), allowed (true) if no other processed results are to disallow, or open (null) to not affect the outcome.

See {@link DataObject::can()} and {@link DataObject::extendedCan()} for context.

Only allow editing of a page if the member satisfies one of the following conditions:

• Is in a group which has access to the subsite this page belongs to
• Is in a group with edit permissions on the "main site"

If there are no subsites configured yet, this logic is skipped.

Define extra database fields

Return a map where the keys are db, has_one, etc, and the values are additional fields/relations to be defined.

This function is used to provide modifications to the form in the CMS by the extension. By default, no changes are made. {@link DataObject->getCMSFields()}.

Please consider using {@link updateFormFields()} to globally add formfields to the record. The method {@link updateCMSFields()} should just be used to add or modify tabs, or fields which are specific to the CMS-context.

Caution: Use {@link FieldList->addFieldToTab()} to add fields.

This function is used to provide modifications to the Validators used on a DataObject.

Caution: Use {@link CompositeValidator->addValidator()} to add Validators.

This function is used to provide modifications to the form used for front end forms. {@link DataObject->getFrontEndFields()}

Caution: Use {@link FieldList->push()} to add fields.

This is used to provide modifications to the form actions used in the CMS. {@link DataObject->getCMSActions()}.

this function is used to provide modifications to the summary fields in CMS by the extension By default, the summaryField() of its owner will merge more fields defined in the extension's $extra_fields['summary_fields']

this function is used to provide modifications to the fields labels in CMS by the extension By default, the fieldLabels() of its owner will merge more fields defined in the extension's $extra_fields['field_labels']

Does the basic duplication, but doesn't write anything this means we can subclass this easier and do more complex relation duplication.

Note that when duplicating including children, everything is written.

When duplicating a page, assign the current subsite ID from the state

Create a duplicate of this page and save it to another subsite

Duplicate relations using a static property to define which ones we want to duplicate

It may be that some relations are not diostinct to sub site so can stay whereas others may need to be duplicated

This was originally deprecated - Use the "cascade_duplicates" config API instead Ideally this would be re-deprecated

Called by ContentController::init();

Use the CMS domain for iframed CMS previews to prevent single-origin violations and SSL cert problems. Always set SubsiteID to avoid errors because a page doesn't exist on the CMS domain.

Inject the subsite ID into the content so it can be used by frontend scripts.

Ensure that valid url segments are checked within the correct subsite of the owner object, even if the current subsiteID is set to some other subsite.

Return a piece of text to keep DataObject cache keys appropriately specific
