[IO] Add StreamPeerGZIP for streaming compression/decompression.
Putting data results in writing the compressed/decompressed output into
a RingBuffer.
You can retrieve the content of the RingBuffer via get_data.
Support both gzip and deflate.

When the stream is over, you must call [method finish] to ensure the internal buffer is properly flushed (make sure to call [method StreamPeer.get_available_bytes] on last time to check if more data needs to be read after that). + </description> + <tutorials> + </tutorials> + <methods> + <method name="clear"> + <return type="void" /> + <description> + Clears this stream, resetting the internal state. + </description> + </method> + <method name="finish"> + <return type="int" enum="Error" /> + <description> + Finalizes the stream, compressing or decompressing any buffered chunk left. + </description> + </method> + <method name="start_compression"> + <return type="int" enum="Error" /> + <param index="0" name="use_deflate" type="bool" default="false" /> + <param index="1" name="buffer_size" type="int" default="65535" /> + <description> + Start the stream in compression mode with the given [param buffer_size], if [param use_deflate] is [code]true[/code] uses deflate instead of GZIP. + </description> + </method> + <method name="start_decompression"> + <return type="int" enum="Error" /> + <param index="0" name="use_deflate" type="bool" default="false" /> + <param index="1" name="buffer_size" type="int" default="65535" /> + <description> + Start the stream in decompression mode with the given [param buffer_size], if [param use_deflate] is [code]true[/code] uses deflate instead of GZIP. + </description> + </method> + </methods> +</class> |
