Interface Summary

Interface	Description
BATManaged	This interface defines behaviors for objects managed by the Block Allocation Table (BAT).
DirectoryEntry	This interface defines methods specific to Directory objects managed by a Filesystem instance.
DocumentEntry	This interface defines methods specific to Document objects managed by a Filesystem instance.
Entry	This interface provides access to an object managed by a Filesystem instance.
POIFSWriterListener	Interface POIFSWriterListener

Class Summary

Class	Description
BlockStore	This abstract class describes a way to read, store, chain and free a series of blocks (be they Big or Small ones)
DirectoryNode	Simple implementation of DirectoryEntry
DocumentDescriptor	Class DocumentDescriptor
DocumentFactoryHelper	A small base class for the various factories, e.g.
DocumentInputStream	This class provides methods to read a DocumentEntry managed by a POIFSFileSystem or NPOIFSFileSystem instance.
DocumentNode	Simple implementation of DocumentEntry for OPOIFS
DocumentOutputStream	This class provides a wrapper over an OutputStream so that Document writers can't accidently go over their size limits
EntryNode	Abstract implementation of Entry Extending classes should override isDocument() or isDirectory(), as appropriate Extending classes must override isDeleteOK()
EntryUtils
FilteringDirectoryNode	A DirectoryEntry filter, which exposes another DirectoryEntry less certain parts.
NDocumentInputStream	This class provides methods to read a DocumentEntry managed by a NPOIFSFileSystem instance.
NDocumentOutputStream	This class provides methods to write a DocumentEntry managed by a NPOIFSFileSystem instance.
NPOIFSDocument	This class manages a document in the NIO POIFS filesystem.
NPOIFSFileSystem	This is the main class of the POIFS system; it manages the entire life cycle of the filesystem.
NPOIFSMiniStore	This class handles the MiniStream (small block store) in the NIO case for NPOIFSFileSystem
NPOIFSStream	This handles reading and writing a stream within a NPOIFSFileSystem.
ODocumentInputStream	This class provides methods to read a DocumentEntry managed by a OPOIFSFileSystem instance.
Ole10Native	Represents an Ole10Native record which is wrapped around certain binary files being embedded in OLE2 documents.
OPOIFSDocument	This class manages a document in a old-style OPOIFS filesystem.
OPOIFSFileSystem	This is the main class of the POIFS system; it manages the entire life cycle of the filesystem.
POIFSDocumentPath	Class POIFSDocumentPath
POIFSFileSystem	Transition class for the move from POIFSFileSystem to OPOIFSFileSystem, and from NPOIFSFileSystem to POIFSFileSystem.
POIFSWriterEvent	Class POIFSWriterEvent

Enum Summary

Enum	Description
FileMagic	The file magic number, i.e.

Exception Summary

Exception	Description
NotOLE2FileException	This exception is thrown when we try to open a file that doesn't seem to actually be an OLE2 file after all
OfficeXmlFileException	This exception is thrown when we try to open a file that's actually an Office 2007+ XML file, rather than an OLE2 file (which is what POIFS works with)
Ole10NativeException
