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.
CompositeInodeLockList	Manages the locks for a list of Inodes, based off an existing lock list.
FileSystemMasterView	This class exposes a read-only view of FileSystemMaster.
Inode<T>	Inode is an abstract class, with information shared by all types of Inodes.
InodeDirectory	Alluxio file system's directory representation in the file system master.
InodeDirectoryIdGenerator	Inode id management for directory inodes.
InodeFile	Alluxio file system's file representation in the file system master.
InodeLockList	Manages the locks for a list of Inode.
InodePathPair	This class represents a pair of LockedInodePaths.
InodeTree	Represents the tree of Inodes.
InodeTree.CreatePathResult	Represents the results of creating a path in the inode tree.
LazyUfsBlockLocationCache	Lazily cache the block locations only when needed.
LockedInodePath	This class represents a path of locked Inode, 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.
MutableLockedInodePath	This class represents an LockedInodePath, where the list of inodes can be extended to gather additional inodes along the path.
NoopUfsAbsentPathCache	This is a noop version of UfsAbsentPathCache.
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	This cache maintains the Alluxio paths which have been synced with 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.LockMode	The type of lock to lock inode paths with.
PersistenceState	The persistence state of a file in the under-storage system.
