true if high compression should be used,
false otherwise.

Unwraps the specified compressed buffer.

Block compression stream. Allows to use LZ4 for stream compression.
Flags of a chunk. Please note, this
None.
Set if chunk is compressed.
Set if high compression has been selected (does not affect decoder,
but might be useful when rewriting)
3 bits for number of passes. Currently only 1 pass (value 0)
is supported.
The inner stream.
The compression mode.
The high compression flag (compression only).
Determines if reading tries to return something ASAP or wait
for full chunk (decompression only).
Isolates inner stream which will not be closed
when this stream is closed.
The block size (compression only).
The buffer.
The buffer length (can be different then _buffer.Length).
The offset in a buffer.
Initializes a new instance of the class.
The inner stream.
The compression mode.
if set to true high compression is used.
Size of the block.
if set to true interactive read mode is used.
It means that method tries to return data as soon as possible.
Please note, that this should be default behavior but has been made optional for
backward compatibility. This constructor will be changed in next major release.
Initializes a new instance of the class.
The inner stream.
The compression mode.
The compression flags.
Size of the block.
Returns NotSupportedException.
Name of the operation.
NotSupportedException
Returns EndOfStreamException.
EndOfStreamException
Tries to read variable length int.
The result.
true if integer has been read, false if end of stream has been
encountered. If end of stream has been encountered in the middle of value
is thrown.
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 instead.
Reads the block of bytes.
Contrary to does not read partial data if possible.
If there is no data (yet) it waits.
The buffer.
The offset.
The length.
Number of bytes read.
Writes the variable length integer.
The value.
Flushes current chunk.
Reads the next chunk from stream.
true if next has been read, or false if it is legitimate end of file.
Throws if end of stream was unexpected.
When overridden in a derived class, gets a value indicating whether the current stream supports reading.
true if the stream supports reading; otherwise, false.
When overridden in a derived class, gets a value indicating whether the current stream supports seeking.
true if the stream supports seeking; otherwise, false.
When overridden in a derived class, gets a value indicating whether the current stream supports writing.
true if the stream supports writing; otherwise, false.
When overridden in a derived class, clears all buffers for this stream and causes any buffered data to be written to the underlying device.
When overridden in a derived class, gets the length in bytes of the stream.
A long value representing the length of the stream in bytes.
When overridden in a derived class, gets or sets the position within the current stream.
The current position within the stream.
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.
The unsigned byte cast to an Int32, or -1 if at the end of the stream.
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.
An array of bytes. When this method returns, the buffer contains the specified byte array with the values between and ( + - 1) replaced by the bytes read from the current source.
The zero-based byte offset in at which to begin storing the data read from the current stream.
The maximum number of bytes to be read from the current stream.
The total number of bytes read into the buffer. This can be less than the number of bytes requested if that many bytes are not currently available, or zero (0) if the end of the stream has been reached.
When overridden in a derived class, sets the position within the current stream.
A byte offset relative to the parameter.
A value of type indicating the reference point used to obtain the new position.
The new position within the current stream.
When overridden in a derived class, sets the length of the current stream.
The desired length of the current stream in bytes.
Writes a byte to the current position in the stream and advances the position within the stream by one byte.
The byte to write to the stream.
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 array of bytes. This method copies bytes from to the current stream.
The zero-based byte offset in at which to begin copying bytes to the current stream.
The number of bytes to be written to the current stream.
Releases the unmanaged resources used by the and optionally releases the managed resources.
true to release both managed and unmanaged resources; false to release only unmanaged resources.
Additional flags for LZ4Stream.
Empty settings. No special behavior.
Allows to use interactive mode, possibly returning partial blocks.
Uses high compression version of algorithm.
Isolates inner stream so it does not get
closed when LZ4 stream is closed.
Default settings.
Originally this type comes from System.IO.Compression,
but it is not present in portable assemblies.
