__construct (array $params)

finishWrite ()

Finish a cache write transaction.

get ( $code, $key)

Get a value.

Parameters

string	$code	Language code
string	$key	Cache key

lateFallback ()

Can this cache type delay fallback lookups to read time?Returning true will cause the fallbacks to be skipped when recaching data, and instead performed via multiple reads if necessary at runtime.This is best when performing lookups is extremely low-cost, such as LCStoreStaticArray with the lateFallback option.When reading from disk or network, trading off the space for fewer lookups may still be a win. Returning false will keep the classic behavior of pre-filling all the fallback chains for each language.

set ( $key, $value)

Set a key to a given value.startWrite() must be called before this is called, and finishWrite() must be called after.

Parameters

string	$key
mixed	$value

startWrite ( $code)

Start a cache write transaction.

Parameters

string $code Language code
