C# Class SIL.Utils.TextWriterStream

Implementation of the COM IStream interface that wraps a C# TextWriter object. This is useful for calling the ITsString.WriteAsXml method from C# code.

Méthodes publiques

Méthode	Description
Clone ( IStream &pstm ) : void	Creates a new stream object with its own seek pointer that references the same bytes as the original stream.
Commit ( int grfCommitFlags ) : void	Ensures that any changes made to a stream object opened in transacted mode are reflected in the parent storage object. If the stream object is opened in direct mode, this method has no effect other than flushing all memory buffers to the next level storage object. The OLE compound file implementation of streams does not support opening streams in transacted mode.
CopyTo ( IStream pstm, long cb, System pcbRead, System pcbWritten ) : void	Copies a specified number of bytes from the current seek pointer in the stream to the current seek pointer in another stream.
LockRegion ( System.Int64 libOffset, System.Int64 cb, int dwLockType ) : void	Restricts access to a specified range of bytes in the stream. Supporting this functionality is optional because some file systems do not provide it.
Read ( byte pv, int cb, System pcbRead ) : void	Reads a specified number of bytes from the stream object into memory, starting at the current seek pointer.
Revert ( ) : void	Discards all changes that have been made to a transacted stream since the last IStream::Commit call. This method has no effect on streams open in direct mode and streams using the OLE compound file implementation of IStream::Revert.
Seek ( long dlibMove, int dwOrigin, System plibNewPosition ) : void	Changes the seek pointer to a new location relative to the current seek pointer or the beginning or end of the stream.
SetSize ( long libNewSize ) : void	Resizes of the stream object.
Stat ( STATSTG &pstatstg, int grfStatFlag ) : void	Retrieves the STATSTG structure for this stream object.
TextWriterStream ( TextWriter writer ) : System	Constructor.
UnlockRegion ( long libOffset, long cb, int dwLockType ) : void	Removes the access restriction on a range of bytes previously restricted with IStream::LockRegion.
Write ( byte pv, int cb, System pcbWritten ) : void	Writes a specified number of bytes into the stream object starting at the current seek pointer.

Method Details

Clone() public méthode

Creates a new stream object with its own seek pointer that references the same bytes as the original stream.

public Clone ( IStream &pstm ) : void
pstm	IStream
Résultat	void

Commit() public méthode

Ensures that any changes made to a stream object opened in transacted mode are reflected in the parent storage object. If the stream object is opened in direct mode, this method has no effect other than flushing all memory buffers to the next level storage object. The OLE compound file implementation of streams does not support opening streams in transacted mode.

public Commit ( int grfCommitFlags ) : void
grfCommitFlags	int
Résultat	void

CopyTo() public méthode

Copies a specified number of bytes from the current seek pointer in the stream to the current seek pointer in another stream.

public CopyTo ( IStream pstm, long cb, System pcbRead, System pcbWritten ) : void
pstm	IStream
cb	long
pcbRead	System
pcbWritten	System
Résultat	void

LockRegion() public méthode

Restricts access to a specified range of bytes in the stream. Supporting this functionality is optional because some file systems do not provide it.

public LockRegion ( System.Int64 libOffset, System.Int64 cb, int dwLockType ) : void
libOffset	System.Int64
cb	System.Int64
dwLockType	int
Résultat	void

Read() public méthode

Reads a specified number of bytes from the stream object into memory, starting at the current seek pointer.

public Read ( byte pv, int cb, System pcbRead ) : void
pv	byte
cb	int
pcbRead	System
Résultat	void

Revert() public méthode

Discards all changes that have been made to a transacted stream since the last IStream::Commit call. This method has no effect on streams open in direct mode and streams using the OLE compound file implementation of IStream::Revert.

public Revert ( ) : void
Résultat	void

Seek() public méthode

Changes the seek pointer to a new location relative to the current seek pointer or the beginning or end of the stream.

public Seek ( long dlibMove, int dwOrigin, System plibNewPosition ) : void

plibNewPosition	System
Résultat	void

SetSize() public méthode
