Member Function Documentation

MemcacheCache::close ( )

Close the cache and free resources.

Definition at line 118 of file

MemcacheCache::flush ( )

Flush the cache.

Definition at line 78 of file

MemcacheCache::getCache (   $id)

Get an object from the cache.


Definition at line 86 of file

References GenericCache\getCacheId(), and GenericCache\getContext().

MemcacheCache::getCacheTime ( )

Get the time at which the data was cached. Note that keys expire in memcache, which means that it's possible that the date will disappear before the data – in this case we'll have to assume the data is still good.

Definition at line 131 of file

MemcacheCache::MemcacheCache (   $context,

Instantiate a cache.

Definition at line 49 of file

References GenericCache\$cacheId, GenericCache\$context, and GenericCache\$fallback.

MemcacheCache::setCache (   $id,

Set an object in the cache. This function should be overridden by subclasses.


Definition at line 106 of file

References $expire, $flag, and GenericCache\getCacheId().

Referenced by setEntireCache().

MemcacheCache::setEntireCache ( $contents)

Set the entire contents of the cache. WARNING: THIS DOES NOT FLUSH THE CACHE FIRST! This is because there is no "scope restriction" for flushing within memcache and therefore a flush here would flush the entire cache, resulting in more subsequent calls to this function, resulting in more flushes, etc.

References setCache().

MemcacheCache::setExpiry (   $expiry)

Set the expiry time (used in Memcache::set)

Definition at line 71 of file

MemcacheCache::setFlag (   $flag)
