Class Summary

Class	Description
BufferFileAdapter	BufferFileAdapter provides a BufferFile implementation which wraps a BufferFileHandle.
BufferFileBlock	BufferFileBlock is used to hold BufferFile blocks for use during block streaming operations.
BufferMgr	BufferMgr provides low-level buffer management and caching.
ChangeMap	ChangeMap facilitates the decoding of change-data to determine if a specific buffer was modified by the corresponding buffer file version.
ChangeMapFile	ChangeMapFile tracks which buffers within a LocalBufferFile have been modified between an older and newer version.
DataBuffer	DataBuffer provides an accessible binary buffer for use with a BufferMgr and BufferFile.
LocalBufferFile	LocalBufferFile implements a BufferFile as block-oriented random-access file.
LocalManagedBufferFile	LocalManagedBufferFile implements a BufferFile as block-oriented random-access file which utilizes a BufferFileManager to identify and facilitate versioning of buffer files.
ManagedBufferFileAdapter	ManagedBufferFileAdapter provides a ManagedBufferFile implementation which wraps a ManagedBufferFileHandle.
VersionFileHandler	VersionFileHandler allows a set of VersionFile's to be used in the dynamic reconstruction of an older BufferFile.
