Method Summary

Modifier and Type	Method	Description
ParsingResult	parsePacket(FilterChainContext ctx, HttpHeader httpPacket, Buffer buffer)	Parse HTTP packet payload, represented by Buffer using specific transfer encoding.
void	prepareSerialize(FilterChainContext ctx, HttpHeader httpHeader, HttpContent content)	This method will be called by HttpCodecFilter to let TransferEncoding prepare itself for the content serialization.
Buffer	serializePacket(FilterChainContext ctx, HttpContent httpContent)	Serialize HTTP packet payload, represented by HttpContent using specific transfer encoding.
boolean	wantDecode(HttpHeader httpPacket)	Return true if this encoding should be used to parse the content of the passed HttpHeader, or false otherwise.
boolean	wantEncode(HttpHeader httpPacket)	Return true if this encoding should be used to serialize the content of the passed HttpHeader, or false otherwise.

Method Details

wantDecode

boolean wantDecode(HttpHeader httpPacket)

Return true if this encoding should be used to parse the content of the passed HttpHeader, or false otherwise.

Parameters:

httpPacket - HttpHeader.

Returns:

true if this encoding should be used to parse the content of the passed HttpHeader, or false otherwise.

wantEncode

boolean wantEncode(HttpHeader httpPacket)

Return true if this encoding should be used to serialize the content of the passed HttpHeader, or false otherwise.

Parameters:

httpPacket - HttpHeader.

Returns:

true if this encoding should be used to serialize the content of the passed HttpHeader, or false otherwise.

prepareSerialize

void prepareSerialize(FilterChainContext ctx,
 HttpHeader httpHeader,
 HttpContent content)

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.

Parameters:

ctx - FilterChainContext

httpHeader - HTTP packet headers.

content - ready HTTP content (might be null).

parsePacket

ParsingResult parsePacket(FilterChainContext ctx,
 HttpHeader httpPacket,
 Buffer buffer)

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

Parameters:

ctx - FilterChainContext

httpPacket - HttpHeader with parsed headers.

buffer - Buffer HTTP message payload.

Returns:

ParsingResult

serializePacket

Buffer serializePacket(FilterChainContext ctx,
 HttpContent httpContent)

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

Parameters:

ctx - FilterChainContext

httpContent - HttpContent with parsed HttpContent.getHttpHeader().

Returns:

serialized Buffer
