Interface	Description
FileMergingCheckpointStateOutputStream.FileMergingSnapshotManagerProxy	A proxy of the FileMergingSnapshotManager that owns this FileMergingCheckpointStateOutputStream, with the interfaces for dealing with physical files.

Class Summary

Class	Description
AbstractFileStateBackend	Deprecated. State backends should no longer implement CheckpointStorage functionality.
AbstractFsCheckpointStorageAccess	An implementation of durable checkpoint storage to file systems.
FileBasedStateOutputStream	A CheckpointStateOutputStream that writes into a specified file and returns a FileStateHandle upon closing.
FileMergingCheckpointStateOutputStream	A CheckpointStateOutputStream that writes into a segment of a file and returns a SegmentFileStateHandle upon closing.
FileStateHandle	StreamStateHandle for state that was written to a file stream.
FsCheckpointMetadataOutputStream	A CheckpointMetadataOutputStream that writes a specified file and directory, and returns a FsCompletedCheckpointStorageLocation upon closing.
FsCheckpointStateToolset	An implementation of CheckpointStateToolset that does file based duplicating with as PathsCopyingFileSystem.
FsCheckpointStorageAccess	An implementation of durable checkpoint storage to file systems.
FsCheckpointStorageLocation	A storage location for checkpoints on a file system.
FsCheckpointStreamFactory	A CheckpointStreamFactory that produces streams that write to a FileSystem.
FsCheckpointStreamFactory.FsCheckpointStateOutputStream	A CheckpointStateOutputStream that writes into a file and returns a StreamStateHandle upon closing.
FsCompletedCheckpointStorageLocation	A CompletedCheckpointStorageLocation that resides on a file system.
FSDataOutputStreamWrapper	Implementation of MetadataOutputStreamWrapper encapsulates the FSDataOutputStream for FsCheckpointMetadataOutputStream.
FsMergingCheckpointStorageAccess	An implementation of file merging checkpoint storage to file systems.
FsMergingCheckpointStorageLocation	An implementation of checkpoint storage location for file merging checkpoints.
FsSegmentDataInputStream	This class is a WrappingProxy for FSDataInputStream that is used to read from a file segment.
MetadataOutputStreamWrapper	The wrapper manages metadata output stream close and commit.
RecoverableStreamWrapper	Implementation of MetadataOutputStreamWrapper encapsulates the RecoverableFsDataOutputStream for FsCheckpointMetadataOutputStream.
RelativeFileStateHandle	A StreamStateHandle for state that was written to a file stream.
