Class Summary

Class	Description
AbstractFileStore	The storage implementation for tar files.
CompactedNodeState	Simple wrapper class for SegmentNodeState to keep track of fully and partially compacted nodes.
CompactionWriter	The CompactionWriter delegates compaction calls to the correct SegmentWriter based on GCGeneration.
FileReaper	Thread-safe class tracking files to be removed.
FileStore	The storage implementation for tar files.
FileStoreBuilder	Builder for creating FileStore instances.
FileStoreGCMonitor	GCMonitor implementation providing the file store gc status.
FileStoreStats
GCIncrement	Utility class to keep track of generations for incremental compaction.
GCJournal	Persists the repository size and the reclaimed size following a cleanup operation in the gc.log file with the format: 'repoSize, reclaimedSize, timestamp, gc generation, gc full generation (since Oak 1.8), number of nodes compacted, root id (since Oak 1.8)'.
GCJournal.GCJournalEntry
GCMemoryBarrier	Responsible for raising the low memory flag whenever the available memory falls under a specified threshold.
GCNodeWriteMonitor	Monitors the compaction cycle and keeps a compacted nodes counter, in order to provide a best effort progress log based on extrapolating the previous size and node count and current size to deduce current node count.
JournalEntry	A value class representing an entry in the revisions journal.
JournalReader	Iterator over the revisions in the journal in reverse order (end of the file to beginning).
LocalGCJournalFile
LocalManifestFile
ManifestChecker
MetricsIOMonitor	This IOMonitor implementations registers the following monitoring endpoints with the Metrics library if available: MetricsIOMonitor.OAK_SEGMENT_SEGMENT_READ_BYTES: a meter metrics for the number of bytes read from tar files MetricsIOMonitor.OAK_SEGMENT_SEGMENT_WRITE_BYTES: a meter metrics for the number of bytes written to tar files MetricsIOMonitor.OAK_SEGMENT_SEGMENT_READ_TIME: a timer metrics for the time spent reading from tar files MetricsIOMonitor.OAK_SEGMENT_SEGMENT_WRITE_TIME: a timer metrics for the time spent writing to tar files
MetricsRemoteStoreMonitor
PriorityCache<K,V>	PriorityCache implements a partial mapping from keys of type K to values of type V.
ReadOnlyFileStore	A read only AbstractFileStore implementation that supports going back to old revisions.
ReadOnlyRevisions
Scheduler	A simple scheduler for executing and scheduling tasks in the background.
TarRevisions	This implementation of Revisions is backed by a journal file where the current head is persisted by calling TarRevisions.tryFlush(Flusher).

Exception Summary

Exception	Description
InvalidFileStoreVersionException	This exception can be thrown during the startup of the FileStore to indicate an incompatible version mismatch between the code that generated the data in the store and the current version of the FileStore.
UnrecoverableArchiveException
