$params include: | |

makeGlobalKey ( $class, $component=null) | |
Make a global cache key. | |
makeKey ( $class, $component=null) | |

WinCacheBagOStuff::merge | ( | $key, | |
callable | $callback, | ||
$exptime = 0, | |||
$attempts = 10, | |||
$flags = 0 ) |
Merge changes into the existing cache value (possibly creating a new one)
The callback function returns the new value given the current value (which will be false if not present), and takes the arguments: (this BagOStuff, cache key, current value, TTL). The TTL parameter is reference set to $exptime. It can be overriden in the callback.
string | $key | |
callable | $callback | Callback method to be executed |
int | $exptime | Either an interval in seconds or a unix timestamp for expiry |
int | $attempts | The amount of times to attempt a merge in case of failure |
