Constructor Detail

Decoder

public Decoder(long maxHeaderListSize,
       int initialHuffmanDecodeCapacity)

Create a new instance.

Parameters:

maxHeaderListSize - This is the only setting that can be configured before notifying the peer. This is because SETTINGS_MAX_HEADER_LIST_SIZE allows a lower than advertised limit from being enforced, and the default limit is unlimited (which is dangerous).

initialHuffmanDecodeCapacity - Size of an intermediate buffer used during huffman decode.

Method Detail

decode

public void decode(int streamId,
          io.netty.buffer.ByteBuf in,
          Http2Headers headers)
            throws Http2Exception

Decode the header block into header fields.

This method assumes the entire header block is contained in in.

Throws:

Http2Exception

setMaxHeaderTableSize

public void setMaxHeaderTableSize(long maxHeaderTableSize)
                           throws Http2Exception

Set the maximum table size. If this is below the maximum size of the dynamic table used by the encoder, the beginning of the next header block MUST signal this change.

Throws:

Http2Exception

setMaxHeaderListSize

public void setMaxHeaderListSize(long maxHeaderListSize,
                        long maxHeaderListSizeGoAway)
                          throws Http2Exception

Throws:

Http2Exception

getMaxHeaderListSize

public long getMaxHeaderListSize()

getMaxHeaderListSizeGoAway

public long getMaxHeaderListSizeGoAway()

getMaxHeaderTableSize

public long getMaxHeaderTableSize()

Return the maximum table size. This is the maximum size allowed by both the encoder and the decoder.
