Member Function Documentation

void lru::InodeCache::Drop ( )

inlinevirtual

Clears all elements from the cache. All memory of internal data structures will be freed but data of cache entries may stay in use, we do not call delete on any user data.

Reimplemented from lru::LruCache< fuse_ino_t, catalog::DirectoryEntry >.

Here is the caller graph for this function:

bool lru::InodeCache::Insert ( const fuse_ino_t &  key, const catalog::DirectoryEntry &  value  )

inlinevirtual

Insert a new key-value pair to the list. If the cache is already full, the least recently used object is removed; afterwards the new object is inserted. If the object is already present it is updated and moved back to the end of the list

Parameters

key	the key where the value is saved
value	the value of the cache entry

Returns

true on insert, false on update

Here is the caller graph for this function:

bool lru::InodeCache::Lookup ( const fuse_ino_t &  key, catalog::DirectoryEntry *  value, bool  update_lru = true  )

inlinevirtual

Retrieve an element from the cache. If the element was found, it will be marked as 'recently used' and returned

Parameters

key	the key to perform a lookup on
value	(out) here the result is saved (not touch in case of miss)

Returns

true on successful lookup, false if key was not found
