Member Function Documentation

void lru::Md5PathCache::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< shash::Md5, catalog::DirectoryEntry >.

bool lru::Md5PathCache::Forget ( const shash::Md5 & key )

inlinevirtual

Forgets about a specific cache entry

Parameters

key	the key to delete from the cache

Returns: true if key was deleted, false if key was not in the cache

Reimplemented from lru::LruCache< shash::Md5, catalog::DirectoryEntry >.

Here is the call graph for this function:

bool lru::Md5PathCache::Insert	(	const shash::Md5 &	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
