__construct()

Wikibase\Lib\Changes\ChangeRow::__construct

(

array

$fields = []

)

(

)

Change::getAge

Exceptions

MWException

if the "time" field is not set

Returns

int Seconds

Implements Wikibase\Lib\Changes\Change.

getField()

Wikibase\Lib\Changes\ChangeRow::getField

(

$name

)

Parameters

string

$name

Exceptions

MWException

if the requested field is not set

Returns

mixed

getFields()

Wikibase\Lib\Changes\ChangeRow::getFields

Implements Wikibase\Lib\Changes\Change.

getInfo()

Wikibase\Lib\Changes\ChangeRow::getInfo

(

$cache = 'no'

)

Returns the info array.

The array is deserialized on the fly. If $cache is set to 'cache', the deserialized version is stored for later re-use.

Usually, the deserialized version is not retained to preserve memory when lots of changes need to be processed. It can however be retained to improve performance in cases where the same object is accessed several times.

Parameters

string

$cache

Set to 'cache' to cache the unserialized version of the info array.

Returns

array

getObjectId()

Wikibase\Lib\Changes\ChangeRow::getObjectId

(

)

Exceptions

MWException

if the "object_id" field is not set
