Public Methods

void CacheNode (fs::PagedVfs & vfs, Digest digest)

Defined at line 18 of file ../../src/storage/blobfs/cache_node.cc

BlobCache & GetCache ()

Returns a reference to the BlobCache.

The BlobCache must outlive all CacheNodes; this method is invoked from the recycler of a

CacheNode.

The implementation of this method must not invoke any other CacheNode methods. The

implementation of this method must not attempt to acquire a reference to |this|.

bool ShouldCache ()

Identifies if the node should be recycled when it is terminated, keeping it cached (although

possibly in a reduced state).

This should be true as long as the blob exists on persistent storage, and would be visible

again on reboot.

The implementation of this method must not invoke any other CacheNode methods. The

implementation of this method must not attempt to acquire a reference to |this|.
