class VersionedStateExtension extends Extension (View source)
Persists versioned state between requests via querystring arguments
Properties
| protected | T | $owner | The object this extension is applied to. |
from Extension |
Methods
Called when this extension is added to a particular class
Temporarily modify the owner. The original owner is ensured to be restored
Clear the current owner, and restore extension to the state prior to the last setOwner()
Helper method to strip eval'ed arguments from a string that's passed to DataObject::$extensions or Object::add_extension().
Invoke extension point. This will prefer explicit extend prefixed
methods.
Auto-append current stage if we're in draft, to avoid relying on session state for this, and the related potential of showing draft content without varying the URL itself.

updateLink(string $link)
Auto-append current stage if we're in draft, to avoid relying on session state for this, and the related potential of showing draft content without varying the URL itself.
Assumes that if the user has access to view the current record in draft stage, they can also view other draft records. Does not concern itself with verifying permissions for performance reasons.
This should also pull through to form actions.
protected bool
hasVersionedQuery(string $link)
Check if link contains versioned queryargs
protected string
getReadingmode()
Get reading mode for the record / controller being decorated
