C# Class Journaler.FileBlockWriter

Inheritance: IBlockWriter

Public Methods

Method	Description
Dispose ( ) : void	Dispose the instance
FileBlockWriter ( string path, int blockSizeInBytes ) : System	Create a new FileBlockWriter
SetSize ( int blocksCount ) : void	Pre-allocates the file on disk with the given size. This improves speed compared to a fragmented file.
Write ( byte block, bool moveToNextBlock ) : void	Write a block to disk and move to next block if specified

Method	Description
CreateFile ( String fileName, int desiredAccess, FileShare shareMode, IntPtr securityAttrs, FileMode creationDisposition, int flagsAndAttributes, IntPtr templateFile ) : SafeFileHandle
GetDiskFreeSpace ( string path, uint &sectorsPerCluster, uint &bytesPerSector, uint &numberOfFreeClusters, uint &totalNumberOfClusters ) : bool
GetDriveSectorSize ( string path ) : uint	Return the sector size of the volume the specified filepath lives on.
OpenStream ( string path, FileMode mode, FileAccess acc, FileShare share, bool sequential, bool useAsync, int blockSize ) : FileStream

Dispose the instance

public Dispose ( ) : void
return	void

Create a new FileBlockWriter

If blockSizeInBytes is smaller or equal to 0. if path is null or empty or if blockSize is not a multiple of the disk sector size.

public FileBlockWriter ( string path, int blockSizeInBytes ) : System
path	string	full path of the new file.
blockSizeInBytes	int	size of the blocks in bytes
return	System

Pre-allocates the file on disk with the given size. This improves speed compared to a fragmented file.

public SetSize ( int blocksCount ) : void
blocksCount	int	Size of the files in number of blocks (size of the file is blockCount * blockSize)
return	void

Write a block to disk and move to next block if specified

public Write ( byte block, bool moveToNextBlock ) : void
block	byte	The block to write to disk
moveToNextBlock	bool	True to move to the next block, False otherwise.
return	void
