class SnapshotPersistenceMetadata

Defined at line 20 of file ../../src/developer/forensics/crash_reports/snapshot_persistence_metadata.h

In-memory metadata about the snapshot store on disk at |snapshot_store_root|.

Note: Clients must use Add and Delete to keep the metadata in sync with the snapshot

store in the filesystem. Use with caution!

Public Methods

void SnapshotPersistenceMetadata (std::string snapshot_store_root, StorageSize max_size)

Defined at line 21 of file ../../src/developer/forensics/crash_reports/snapshot_persistence_metadata.cc

bool RecreateFromFilesystem ()

Recreates the metadata from the snapshot store at |snapshot_store_root_|.

Returns false if the |metadata| does not accurately represent the filesystem and the underlying

directory can't safely be used.
