C# Class Yodiwo.PipeStream

PipeStream is a thread-safe read/write data stream for use between two threads in a single-producer/single-consumer type problem.
2006/10/13 1.0 - initial version. Update on 2008/10/9 1.1 - uses Monitor instead of Manual Reset events for more elegant synchronicity. Update on 2014/12/15 1.2 - bugfix for read method not using offset - thanks Jörgen Sigvardsson, replace NotImplementedExceptions with NotSupportedException

Public Methods

Method Description
Dispose ( ) : void

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
Flush ( ) : void

When overridden in a derived class, clears all buffers for this stream and causes any buffered data to be written to the underlying device.
Read ( byte buffer, int offset, int count ) : int

When overridden in a derived class, reads a sequence of bytes from the current stream and advances the position within the stream by the number of bytes read.
Seek ( long offset, SeekOrigin origin ) : long

When overridden in a derived class, sets the position within the current stream.
SetLength ( long value ) : void

When overridden in a derived class, sets the length of the current stream.
Write ( byte buffer, int offset, int count ) : void

When overridden in a derived class, writes a sequence of bytes to the current stream and advances the current position within this stream by the number of bytes written.

Private Methods

Method Description
ReadAvailable ( int count ) : bool

Returns true if there are

Method Details

Dispose() public method

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
public Dispose ( ) : void
return void

Flush() public method

When overridden in a derived class, clears all buffers for this stream and causes any buffered data to be written to the underlying device.
An I/O error occurs.
public Flush ( ) : void
return void

Read() public method

When overridden in a derived class, reads a sequence of bytes from the current stream and advances the position within the stream by the number of bytes read.
The sum of offset and count is larger than the buffer length. Methods were called after the stream was closed. The stream does not support reading. buffer is null. An I/O error occurs. offset or count is negative.
public Read ( byte buffer, int offset, int count ) : int
buffer byte An array of bytes. When this method returns, the buffer contains the specified byte array with the values between offset and (offset + count - 1) replaced by the bytes read from the current source.
offset int The zero-based byte offset in buffer at which to begin storing the data read from the current stream.
count int The maximum number of bytes to be read from the current stream.
return int

Seek() public method

When overridden in a derived class, sets the position within the current stream.
An I/O error occurs. The stream does not support seeking, such as if the stream is constructed from a pipe or console output. Methods were called after the stream was closed.
public Seek ( long offset, SeekOrigin origin ) : long
offset long A byte offset relative to the origin parameter.
origin SeekOrigin A value of type indicating the reference point used to obtain the new position.
return long

SetLength() public method

When overridden in a derived class, sets the length of the current stream.
The stream does not support both writing and seeking, such as if the stream is constructed from a pipe or console output. An I/O error occurs. Methods were called after the stream was closed.
public SetLength ( long value ) : void
value long The desired length of the current stream in bytes.
return void

Write() public method

When overridden in a derived class, writes a sequence of bytes to the current stream and advances the current position within this stream by the number of bytes written.
An I/O error occurs. The stream does not support writing. Methods were called after the stream was closed. buffer is null. The sum of offset and count is greater than the buffer length. offset or count is negative.
public Write ( byte buffer, int offset, int count ) : void
buffer byte An array of bytes. This method copies count bytes from buffer to the current stream.
offset int The zero-based byte offset in buffer at which to begin copying bytes to the current stream.
count int The number of bytes to be written to the current stream.
return void
