Parser cache specific expiry check. More...
Public Member Functions | |
__wakeup () | |
expired ( $touched) | |
Return true if this cached output object predates the global or per-article cache invalidation timestamps, or if it comes from an incompatible older version. | |
getCacheExpiry () | |
Returns the number of seconds after which this object should expire. | |
getCacheRevisionId () | |
getCacheTime () | |
getUsedOptions () | |
Returns the options from its ParserOptions which have been taken into account to produce the output. | |
isCacheable () | |
isDifferentRevision ( $id) | |
Return true if this cached output object is for a different revision of the page. | |
recordOption (string $option) | |
Tags a parser option for use in the cache key for this parser output. | |
recordOptions (array $options) | |
Tags a list of parser option names for use in the cache key for this parser output. | |
setCacheRevisionId ( $id) | |
setCacheTime ( $t) | |
setCacheTime() sets the timestamp expressing when the page has been rendered. | |
updateCacheExpiry ( $seconds) | |
Sets the number of seconds after which this object should expire. | |
Static Public Member Functions | |
static | newFromJsonArray (JsonUnserializer $unserializer, array $json) |
Creates a new instance of the class and initialized it from the $json array. | |
Public Attributes | |
int null | $mCacheExpiry = null |
Seconds after which the object should expire, use 0 for not cacheable. | |
int null | $mCacheRevisionId = null |
Revision ID that was parsed. | |
string int | $mCacheTime = '' |
TS_MW timestamp when this object was generated, or -1 for not cacheable. | |
Protected Member Functions | |
initFromJson (JsonUnserializer $unserializer, array $jsonData) | |
Initialize member fields from an array returned by jsonSerialize(). | |
toJsonArray () | |
Returns a JSON serializable structure representing this CacheTime instance. | |
Protected Attributes | |
true[] | $mParseUsedOptions = [] |
ParserOptions which have been taken into account to produce output, option names stored in array keys. | |

CacheTime::__wakeup | ( | ) |
Reimplemented in ParserOutput.
Definition at line 288 of file CacheTime.php.
CacheTime::expired | ( | $touched | ) |
Return true if this cached output object predates the global or per-article cache invalidation timestamps, or if it comes from an incompatible older version.
string | $touched | The affected article's last touched timestamp |

References $wgCacheEpoch.
CacheTime::getCacheExpiry | ( | ) |
Returns the number of seconds after which this object should expire.
This method is used by ParserCache to determine how long the ParserOutput can be cached. The timestamp of expiry can be calculated by adding getCacheExpiry() to getCacheTime(). The value returned by getCacheExpiry is smaller or equal to the smallest number that was provided to a call of updateCacheExpiry(), and smaller or equal to the value of $wgParserCacheExpireTime.

CacheTime::updateCacheExpiry | ( | $seconds | ) |
Sets the number of seconds after which this object should expire.
This value is used with the ParserCache. If called with a value greater than the value provided at any previous call, the new call has no effect. The value returned by getCacheExpiry is smaller or equal to the smallest number that was provided as an argument to updateCacheExpiry().
Avoid using 0 if at all possible. Consider JavaScript for highly dynamic content.
NOTE: Beware that reducing the TTL for reasons that do not relate to "dynamic content", may have the side-effect of incurring more RefreshLinksJob executions. See also WikiPage::triggerOpportunisticLinksUpdate.
