Interface Summary

Interface	Description
InodeDirectoryView	Read-only interface for an inode directory.
InodeFileView	Read-only interface for an inode file.
InodeLockList	Represents a locked path within the inode tree.
InodeView	Read-only view of an inode.
UfsAbsentPathCache	Cache for recording information about paths that are not present in UFS.
UfsBlockLocationCache	Cache for block locations in the UFS.

Class Summary

Class	Description
AsyncUfsAbsentPathCache	This is a UfsAbsentPathCache which implements asynchronous addition and removal to the cache, since the processing of the path may be slow.
CheckpointedIdHashSet	A concurrent hash set of Long values that supports writing to and restoring from checkpoints.
CompositeInodeLockList	Manages the locks for a list of inodes, based off an existing lock list.
Edge	An edge in the inode tree.
EdgeEntry	Representation for an edge and the inode it points to.
FileSystemMasterView	This class exposes a read-only view of FileSystemMaster.
Inode	Base class for read only inodes.
InodeCounter	A checkpointed long adder.
InodeDirectory	Forwarding wrapper around an inode directory view.
InodeDirectoryIdGenerator	Inode id management for directory inodes.
InodeFile	Forwarding wrapper around an inode file view.
InodeLockManager	Class for managing inode locking.
InodePathPair	This class represents a pair of LockedInodePaths.
InodeTree	Represents the tree of Inodes.
InodeTreeBufferedIterator	Used to iterate this InodeTree's state, while doing a read-ahead buffering.
InodeTreePersistentState	Class for managing persistent inode tree state.
LazyUfsBlockLocationCache	Lazily cache the block locations only when needed.
LockedInodePath	This class represents a locked path within the inode tree, starting from the root.
LockedInodePathList	This class represents a list of locked inodePaths.
LockingScheme	This class represents information about how a path should be locked.
MountTable	This class is used for keeping track of Alluxio mount points.
MountTable.Resolution	This class represents a UFS path after resolution.
MountTable.ReverseResolution	This class represents a Alluxio path after reverse resolution.
MutableInode<T extends MutableInode>	MutableInode is an abstract class, with information shared by all types of Inodes.
MutableInodeDirectory	Alluxio file system's directory representation in the file system master.
MutableInodeFile	Alluxio file system's file representation in the file system master.
NoopUfsAbsentPathCache	This is a noop version of UfsAbsentPathCache.
PinnedInodeFileIds	Keeps track of which files are pinned.
ReplicationLimitedFileIds	Keeps track of which files have limited replication factors.
SimpleInodeLockList	A simple inode lock list.
SyncCheck	Returned by UfsSyncPathCache.shouldSyncPath(alluxio.AlluxioURI, long, alluxio.file.options.DescendantType) indicating whether a sync is needed as well as the time of the last sync if one is not needed.
SyncCheck.SyncResult	Information about the result of a synchronization, created by calling SyncCheck.syncSuccess() or SyncCheck.skippedSync(), or using SyncCheck.SyncResult.INVALID_RESULT if the sync failed due to an external reason.
ToBePersistedFileIds	Keeps track of which files are in the TO_BE_PERSISTED persistence state.
TtlBucket	A bucket with all inodes whose ttl value lies in the bucket's time interval.
TtlBucketList	A list of non-empty TtlBuckets sorted by ttl interval start time of each bucket.
UfsAbsentPathCache.Factory	Factory class for UfsAbsentPathCache.
UfsBlockLocationCache.Factory	Factory class for UfsBlockLocationCache.
UfsSyncPathCache	A cache of paths that have been synchronized or have been marked as not being synchronized with the UFS.
UfsSyncUtils	Util methods for UFS sync.
UfsSyncUtils.SyncPlan	A class describing how to sync an inode with the ufs.

Enum Summary

Enum	Description
InodeTree.LockPattern	Patterns of inode path locking.
PersistenceState	The persistence state of a file in the under-storage system.
