Constructor & Destructor Documentation

__construct()

MediaWiki\Storage\RevisionSlots::__construct

(

$slots

)

Parameters

SlotRecord[] | callable

$slots

SlotRecords, or a callback that returns such a structure.

Definition at line 43 of file RevisionSlots.php.

Member Function Documentation

__sleep()

MediaWiki\Storage\RevisionSlots::__sleep

(

)

Implemented to defy serialization.

Exceptions

LogicException

always

Definition at line 71 of file RevisionSlots.php.

computeSha1()

MediaWiki\Storage\RevisionSlots::computeSha1

(

)

Computes the combined hash of the revisions's slots.

Note

For backwards compatibility, the combined hash of a single slot is that slot's hash. For consistency, the combined hash of an empty set of slots is the hash of the empty string.

@warn This is potentially expensive! It may cause all slot's content to be loaded and deserialized, then re-serialized and hashed.

Returns

string

computeSize()

MediaWiki\Storage\RevisionSlots::computeSize

(

)

Computes the total nominal size of the revision's slots, in bogo-bytes.

@warn This is potentially expensive! It may cause all slot's content to be loaded and deserialized.

Returns

int

getContent()

MediaWiki\Storage\RevisionSlots::getContent

(

$role

)

Returns the Content of the given slot.

Call getSlotNames() to get a list of available slots.

Note that for mutable Content objects, each call to this method will return a fresh clone.

Parameters

string

$role

The role name of the desired slot

Exceptions

RevisionAccessException

if the slot does not exist or slot data could not be lazy-loaded.

Returns

Content

getSlot()

MediaWiki\Storage\RevisionSlots::getSlot

(

$role

)

Returns the SlotRecord of the given slot.

Call getSlotNames() to get a list of available slots.

Parameters

string

$role

The role name of the desired slot

Exceptions

RevisionAccessException

if the slot does not exist or slot data could not be lazy-loaded.

Returns

SlotRecord

getSlotRoles()

MediaWiki\Storage\RevisionSlots::getSlotRoles

(

)

Returns the slot names (roles) of all slots present in this revision.

getContent() will succeed only for the names returned by this method.

Returns

string[]

getSlots()

MediaWiki\Storage\RevisionSlots::getSlots

(

)

Returns an associative array that maps role names to SlotRecords.

Each SlotRecord represents the content meta-data of a slot, together they define the content of a revision.

Note

This may cause the content meta-data for the revision to be lazy-loaded.

Returns

SlotRecord[] revision slot/content rows, keyed by slot role name.
