메소드	설명
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.
LZ4Stream ( Stream innerStream, CompressionMode compressionMode, LZ4StreamFlags compressionFlags = LZ4StreamFlags.Default, int blockSize = 1024*1024 ) : System	Initializes a new instance of the LZ4Stream class.
LZ4Stream ( Stream innerStream, LZ4StreamMode compressionMode, LZ4StreamFlags compressionFlags = LZ4StreamFlags.Default, int blockSize = 1024*1024 ) : System	Initializes a new instance of the LZ4Stream class.
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.
ReadByte ( ) : int	Reads a byte from the stream and advances the position within the stream by one byte, or returns -1 if at the end of the stream.
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.
WriteByte ( byte value ) : void	Writes a byte to the current position in the stream and advances the position within the stream by one byte.

Dispose ( bool disposing ) : void	Releases the unmanaged resources used by the T:System.IO.Stream and optionally releases the managed resources.

AcquireNextChunk ( ) : bool	Reads the next chunk from stream.
CombineLZ4Flags ( bool highCompression, bool interactiveRead ) : LZ4StreamFlags	Combines the LZ4 flags.
EndOfStream ( ) : EndOfStreamException	Returns EndOfStreamException.
FlushCurrentChunk ( ) : void	Flushes current chunk.
LZ4Stream ( Stream innerStream, CompressionMode compressionMode, bool highCompression, int blockSize = 1024*1024, bool interactiveRead = false ) : System
LZ4Stream ( Stream innerStream, LZ4StreamMode compressionMode, bool highCompression, int blockSize = 1024*1024, bool interactiveRead = false ) : System
NotSupported ( string operationName ) : NotSupportedException	Returns NotSupportedException.
ReadBlock ( byte buffer, int offset, int length ) : int	Reads the block of bytes. Contrary to Stream.Read does not read partial data if possible. If there is no data (yet) it waits.
ReadVarInt ( ) : ulong	Reads the variable length int. Work with assumption that value is in the stream and throws exception if it isn't. If you want to check if value is in the stream use TryReadVarInt instead.
ToLZ4StreamMode ( CompressionMode compressionMode ) : LZ4StreamMode	Converts CompressionMode to LZ4StreamMode.
TryReadVarInt ( ulong &result ) : bool	Tries to read variable length int.
WriteVarInt ( ulong value ) : void	Writes the variable length integer.
