C# Class NetworkCommsDotNet.Tools.StreamTools.ThreadSafeStream

A wrapper around a stream to ensure it can be accessed in a thread safe way. The .net implementation of Stream.Synchronized is not suitable on its own.

Inheritance: Stream, IDisposable

Public Methods

Method	Description
CopyTo ( Stream destinationStream, long startPosition, long length, int writeBufferSize, double timeoutMSPerKBWrite = 1000, int minTimeoutMS = 500 ) : double	Copies data specified by start and length properties from internal stream to the provided stream.
Dispose ( ) : void	Disposes the internal stream if DiposeInnerStreamOnDispose is true. Use Close() to close the inner stream regardless of DiposeInnerStreamOnDispose.
Dispose ( bool forceDispose ) : void	Disposes the internal stream. If DiposeInnerStreamOnDispose is false, forceDispose must be true to dispose of the internal stream.
Flush ( ) : void
GetBuffer ( ) : byte[]	Attempts to return the buffer associated with the internal stream. In certain circumstances this is more efficient than copying the stream contents into a new buffer using ToArray. If the internal stream is not a memory stream will throw InvalidCastException. If access to the buffer is not allowed will throw an UnauthorizedAccessException.
MD5 ( ) : string	Return the MD5 hash of the current ThreadSafeStream as a string
MD5 ( long start, int length ) : string	Return the MD5 hash of part of the current ThreadSafeStream as a string
Read ( byte buffer, int offset, int count ) : int
Seek ( long offset, SeekOrigin origin ) : long
SetLength ( long value ) : void
ThreadSafeStream ( Stream stream ) : System	Create a thread safe stream. Once any actions are complete the stream must be correctly disposed by the user.
ThreadSafeStream ( Stream stream, bool closeStreamAfterSend ) : System	Create a thread safe stream.
ToArray ( int numberZeroBytesPrefex ) : byte[]	Returns data from entire Stream
ToArray ( long start, long length, int numberZeroBytesPrefix, int numberZeroBytesAppend ) : byte[]	Returns data from the specified portion of Stream
Write ( byte buffer, int offset, int count ) : void
Write ( byte buffer, long startPosition ) : void	Writes the provided buffer to the internal stream starting at the provided position within the internal stream

Method Details

CopyTo() public method

Copies data specified by start and length properties from internal stream to the provided stream.

public CopyTo ( Stream destinationStream, long startPosition, long length, int writeBufferSize, double timeoutMSPerKBWrite = 1000, int minTimeoutMS = 500 ) : double
destinationStream	Stream	The destination stream to write to
startPosition	long
length	long
writeBufferSize	int	The buffer size to use for copying stream contents
timeoutMSPerKBWrite	double	The timouts in milliseconds per KB to write
minTimeoutMS	int	The minimum time allowed for any sized copy
return	double

Dispose() public method

Disposes the internal stream if DiposeInnerStreamOnDispose is true. Use Close() to close the inner stream regardless of DiposeInnerStreamOnDispose.

public Dispose ( ) : void
return	void

Dispose() public method

Disposes the internal stream. If DiposeInnerStreamOnDispose is false, forceDispose must be true to dispose of the internal stream.

public Dispose ( bool forceDispose ) : void
forceDispose	bool	If true the internal stream will be disposed regardless of value.
return	void

Flush() public method

public Flush ( ) : void
return	void

GetBuffer() public method

Attempts to return the buffer associated with the internal stream. In certain circumstances this is more efficient than copying the stream contents into a new buffer using ToArray. If the internal stream is not a memory stream will throw InvalidCastException. If access to the buffer is not allowed will throw an UnauthorizedAccessException.

public GetBuffer ( ) : byte[]
return	byte[]

MD5() public method

Return the MD5 hash of the current ThreadSafeStream as a string

public MD5 ( ) : string
return	string

MD5() public method

Return the MD5 hash of part of the current ThreadSafeStream as a string

public MD5 ( long start, int length ) : string
start	long	The start position in the stream
length	int	The length of stream to MD5
return	string

Read() public method

public Read ( byte buffer, int offset, int count ) : int
buffer	byte
offset	int
count	int
return	int

Seek() public method

public Seek ( long offset, SeekOrigin origin ) : long
offset	long
origin	SeekOrigin
return	long

SetLength() public method

public SetLength ( long value ) : void
value	long
return	void

ThreadSafeStream() public method

Create a thread safe stream. Once any actions are complete the stream must be correctly disposed by the user.

public ThreadSafeStream ( Stream stream ) : System
stream	Stream	The stream to make thread safe
return	System

ThreadSafeStream() public method

Create a thread safe stream.

public ThreadSafeStream ( Stream stream, bool closeStreamAfterSend ) : System
stream	Stream	The stream to make thread safe.
closeStreamAfterSend	bool	If true the provided stream will be disposed once data has been written to the network. If false the stream must be disposed of correctly by the user
return	System

ToArray() public method

Returns data from entire Stream

public ToArray ( int numberZeroBytesPrefex ) : byte[]
numberZeroBytesPrefex	int	If non zero will append N 0 value bytes to the start of the returned array
return	byte[]

ToArray() public method

Returns data from the specified portion of Stream

public ToArray ( long start, long length, int numberZeroBytesPrefix, int numberZeroBytesAppend ) : byte[]
start	long	The start position of the desired bytes
length	long	The total number of desired bytes, not including the zero byte prefix and append parameters
numberZeroBytesPrefix	int	If non zero will append N 0 value bytes to the start of the returned array
numberZeroBytesAppend	int	If non zero will append N 0 value bytes to the end of the returned array
return	byte[]

Write() public method

public Write ( byte buffer, int offset, int count ) : void
buffer	byte
offset	int
count	int
return	void

Write() public method

Writes the provided buffer to the internal stream starting at the provided position within the internal stream

public Write ( byte buffer, long startPosition ) : void
buffer	byte
startPosition	long
return	void
