Открытые методы

Метод	Описание
ChangeExtension ( string extension, bool isReadOnly, bool isSharingEnabled ) : void	Changes the extension of the current file.
ChangeShareMode ( bool isReadOnly, bool isSharingEnabled ) : void	Reopens the file with different permissions.
CommitChanges ( FileHeaderBlock header ) : void	Occurs when committing the following data to the disk. This will copy any pending data to the disk in a manner that will protect against corruption.
CreateFile ( CustomFileStream stream, MemoryPool pool, int fileStructureBlockSize ) : DiskMedium	Creates a DiskMedium from a stream. This will initialize the stream as an empty file structure. This will not check if the file is truely a new file. If calling this with an existing archive file, it will overwrite the table of contents, corrupting the file.
CreateIoSession ( ) : BinaryStreamIoSessionBase	Creates a BinaryStreamIoSessionBase that can be used to read from this disk medium.
CreateMemoryFile ( MemoryPool pool, int fileStructureBlockSize ) : DiskMedium	Creates a DiskMedium that is entirely based in memory.
Dispose ( ) : void	Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
OpenFile ( CustomFileStream stream, MemoryPool pool, int fileStructureBlockSize ) : DiskMedium	Creates a DiskMedium from a stream. This will read the existing header from the stream.
RollbackChanges ( ) : void	Occurs when rolling back a transaction. This will free up any temporary space allocated for the change.

Метод	Описание
DiskMedium ( IDiskMediumCoreFunctions disk, FileHeaderBlock header ) : System	Class is created through static methods of this class.

Описание методов

ChangeExtension() публичный Метод

Changes the extension of the current file.

public ChangeExtension ( string extension, bool isReadOnly, bool isSharingEnabled ) : void
extension	string	the new extension
isReadOnly	bool	If the file should be reopened as readonly
isSharingEnabled	bool	If the file should share read privileges.
Результат	void

ChangeShareMode() публичный Метод

Reopens the file with different permissions.

public ChangeShareMode ( bool isReadOnly, bool isSharingEnabled ) : void
isReadOnly	bool	If the file should be reopened as readonly
isSharingEnabled	bool	If the file should share read privileges.
Результат	void

CommitChanges() публичный Метод

Occurs when committing the following data to the disk. This will copy any pending data to the disk in a manner that will protect against corruption.

public CommitChanges ( FileHeaderBlock header ) : void
header	FileHeaderBlock
Результат	void

CreateFile() публичный статический Метод

Creates a DiskMedium from a stream. This will initialize the stream as an empty file structure.

This will not check if the file is truely a new file. If calling this with an existing archive file, it will overwrite the table of contents, corrupting the file.

public static CreateFile ( CustomFileStream stream, MemoryPool pool, int fileStructureBlockSize ) : DiskMedium
stream	CustomFileStream	An open to use. The /// will assume ownership of this .
pool	GSF.IO.Unmanaged.MemoryPool	the to allocate data from
fileStructureBlockSize	int	the block size of the file structure. Usually 4kb.
Результат	DiskMedium

CreateIoSession() публичный Метод

Creates a BinaryStreamIoSessionBase that can be used to read from this disk medium.

public CreateIoSession ( ) : BinaryStreamIoSessionBase
Результат	GSF.IO.Unmanaged.BinaryStreamIoSessionBase

CreateMemoryFile() публичный статический Метод

Creates a DiskMedium that is entirely based in memory.

public static CreateMemoryFile ( MemoryPool pool, int fileStructureBlockSize ) : DiskMedium
pool	GSF.IO.Unmanaged.MemoryPool	the to allocate data from
fileStructureBlockSize	int	the block size of the file structure. Usually 4kb.
Результат	DiskMedium

Dispose() публичный Метод

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

public Dispose ( ) : void
Результат	void

OpenFile() публичный статический Метод

Creates a DiskMedium from a stream. This will read the existing header from the stream.

public static OpenFile ( CustomFileStream stream, MemoryPool pool, int fileStructureBlockSize ) : DiskMedium
stream	CustomFileStream	An open to use. The /// will assume ownership of this .
pool	GSF.IO.Unmanaged.MemoryPool	The to allocate data from.
fileStructureBlockSize	int	the block size of the file structure. Usually 4kb.
Результат	DiskMedium

RollbackChanges() публичный Метод

Occurs when rolling back a transaction. This will free up any temporary space allocated for the change.

public RollbackChanges ( ) : void
Результат	void
