|
19
|
|
|
* PT15M. When not given, it is only once. If the source of the |

|
21
|
|
|

|
22
|
|
|
* A value of 0, an absent parameter, or null all mean populate once |
|
23
|
|
|
* and do not attempt to look for new data later. Whenever an poll |
|
24
|
|
|
* occurs, the updating system will look for a file with the most |
|
25
|
|
|
* recent timestamp and assume that one with the most recent data |
|
26
|
|
|
* set, replacing the local cache of the lookup data. |

|
28
|
|
|
* @param bool $injective If the underlying map is injective (keys and values are unique) |
|
29
|
|
|
* then optimizations can occur internally by setting this to true |
|
30
|
|
|
* @param int $firstCacheTimeoutMs How long to wait (in ms) for the first run of the cache to |
|
31
|
|
|
* populate. 0 indicates to not wait |
