Check whether executing a given set of increment operations would exceed any defined limit, without actually performing the increment.

Parameters

LimitOperation[]

$operations

Returns

LimitBatchResult

Definition at line 93 of file WRStatsRateLimiter.php.

resetCurrentTime()

Wikimedia\WRStats\WRStatsRateLimiter::resetCurrentTime

(

)

Forget a time set with setCurrentTime().

Use the actual current time.

(

$now

)

Set the current time.

Parameters

float | int

$now

tryIncr()

Wikimedia\WRStats\WRStatsRateLimiter::tryIncr	(	string	$condName,
		EntityKey	$entityKey = null,
			$amount = 1 )

Check if the limit would be exceeded by incrementing the specified metric.

If not, increment it.

Parameters

string	$condName
EntityKey | null	$entityKey
int	$amount

Returns

LimitOperationResult

Definition at line 139 of file WRStatsRateLimiter.php.

tryIncrBatch()

Wikimedia\WRStats\WRStatsRateLimiter::tryIncrBatch

(

array

$operations
