decode

void decode(ByteBufAllocator alloc,
 ByteBuf headerBlock,
 SpdyHeadersFrame frame)
     throws Exception

Description copied from class: SpdyHeaderBlockDecoder

Decodes a SPDY Header Block, adding the Name/Value pairs to the given Headers frame. If the header block is malformed, the Headers frame will be marked as invalid. A stream error with status code PROTOCOL_ERROR must be issued in response to an invalid frame.

Specified by:

decode in class SpdyHeaderBlockDecoder

Parameters:

alloc - the ByteBufAllocator which can be used to allocate new ByteBufs

headerBlock - the HeaderBlock to decode

frame - the Headers frame that receives the Name/Value pairs

Throws:

Exception - If the header block is malformed in a way that prevents any future decoding of any other header blocks, an exception will be thrown. A session error with status code PROTOCOL_ERROR must be issued.
