public void prepareSerialize(FilterChainContext ctx,
                             HttpHeader httpHeader,
                             HttpContent httpContent)

Description copied from interface: TransferEncoding

This method will be called by HttpCodecFilter to let TransferEncoding prepare itself for the content serialization. At this time TransferEncoding is able to change, update HTTP packet headers.

Specified by:

prepareSerialize in interface TransferEncoding

Parameters:

ctx - FilterChainContext

httpHeader - HTTP packet headers.

httpContent - ready HTTP content (might be null).

parsePacket

public ParsingResult parsePacket(FilterChainContext ctx,
                                 HttpHeader httpPacket,
                                 Buffer input)

Parse HTTP packet payload, represented by Buffer using specific transfer encoding.

Specified by:

parsePacket in interface TransferEncoding

Parameters:

ctx - FilterChainContext

httpPacket - HttpHeader with parsed headers.

input - Buffer HTTP message payload.

Returns:

ParsingResult

serializePacket

public Buffer serializePacket(FilterChainContext ctx,
                              HttpContent httpContent)

Serialize HTTP packet payload, represented by HttpContent using specific transfer encoding.

Specified by:

serializePacket in interface TransferEncoding

Parameters:
