C# Class Revenj.Utility.ChunkedMemoryStream

In memory stream with 8192 blocks to avoid LOH issues. Since .NET places objects larger that 85000 bytes into LOH, avoid it as much as possible by using list of smaller blocks.

Public Methods

Method	Description
ChunkedMemoryStream ( Stream another ) : System	Create in memory stream based on another stream. Provided stream will not be disposed.
ChunkedMemoryStream ( Stream another, bool dispose, bool reset ) : System	Create in memory stream based on another stream. Specify whether should provided stream be disposed after copying.
Close ( ) : void	Close current stream. Stream will be added to pool if required. Doesn't release allocated buffers
CopyTo ( ChunkedMemoryStream other ) : void
CopyTo ( Stream stream ) : void	Optimized version of copy to stream
CopyTo ( byte target, int offset ) : void	Copy stream to target buffer
Create ( ) : ChunkedMemoryStream	Create or get a new instance of memory stream Stream is bound to thread and must be released from the same thread
Equals ( Stream another ) : bool	Compare two streams. Length and content will be compared.
Flush ( ) : void	Flush stream. Does nothing.
GetReader ( ) : TextReader	Reuse same text reader on this stream.
GetWriter ( ) : TextWriter	Reuse same text writer on this stream.
Matches ( byte compare ) : bool	Check if stream starts with provided byte[] and matches it's length Provided byte[] must be smaller than 8192 bytes
Read ( byte buffer, int offset, int count ) : int	Read buffer from the stream. Can return less then specified count if remaining block size is less than specified count
ReadByte ( ) : int	Read a single byte
Reset ( ) : void	Set length and position to 0
Seek ( long offset, SeekOrigin origin ) : long	Seek to position in the stream.
Send ( Socket socket ) : void	Send entire stream to provided socket.
SetLength ( long value ) : void	Set new length of the stream. Adjusts the current position if new length is larger then it.
Static ( ) : ChunkedMemoryStream	Create reusable stream. Disposing the stream only has the effect of resetting it.
ToBase64Stream ( ) : Stream	Convert stream to Base 64 String representation in stream.
ToBase64Writer ( TextWriter sw ) : void	Convert stream to Base 64 String representation in the provided writer.
ToPostgresBytea ( TextWriter sw ) : void	Convert stream to Postgres representation of bytea
ToString ( ) : string	Show content of the stream as string
UseBufferedReader ( TextReader reader ) : BufferedTextReader	Reuse buffered text reader associated with this stream. Provide input text reader as data source. Buffered text reader will be initialized with provided input
UseBufferedReader ( string value ) : BufferedTextReader	Reuse buffered text reader associated with this stream. Provide input string as data source. Buffered text reader will be initialized with provided input
Write ( byte buffer, int offset, int count ) : void	Write buffer to stream. Advances current position by count. Increases length if necessary. New blocks will be added as required. It's best to use buffer of size 8192
WriteByte ( byte value ) : void	Write byte to stream. Advances current position by one. Adds a new block if necessary.
