public AsciiString decode(ByteBuf buf, int length) throws Http2Exception

Decompresses the given Huffman coded string literal.

Parameters
buf:ByteBuf

the string literal to be decoded

Returns:AsciiString

the output stream for the compressed data

processback to summary
public boolean process(byte input)

Implements io.netty.util.ByteProcessor.process.

This should never be called from anything but this class itself!

Returns:boolean

Doc from io.netty.util.ByteProcessor.process.

true if the processor wants to continue the loop and handle the next byte in the buffer. false if the processor wants to stop handling bytes and abort the loop.
