Constructor & Destructor Documentation

◆ __construct()

JobQueueMemory::__construct ( array $params )

Stability: stable: to call

Parameters

array

$params

type : A job type, 'default' if typeAgnostic is set

domain : A DB domain ID
idGenerator : A GlobalIdGenerator instance.
wanCache : An instance of WANObjectCache to use for caching [default: none]
stats : An instance of StatsdDataFactoryInterface [default: none]
claimTTL : Seconds a job can be claimed for exclusive execution [default: forever]
maxTries : Total times a job can be tried, assuming claims expire [default: 3]
order : Queue order, one of ("fifo", "timestamp", "random") [default: variable]
readOnlyReason : Mark the queue as read-only with this reason [default: false]
typeAgnostic : If the jobqueue should operate agnostic to the job types
