Inherits: PacketProcessor

HTTP multipart encoding adapter for multipart/x-mixed-replace streaming.

Public Attributes

Return	Name	Description
`Connection::Ptr`	`connection`	HTTP connection for sending the initial response header.
`std::string`	`contentType`	Content-Type of each part (e.g. "image/jpeg").
`bool`	`isBase64`	If true, adds "Content-Transfer-Encoding: base64" to each part.
`bool`	`initial`	True until the first chunk is processed and the boundary header emitted.
`PacketSignal`	`emitter`

connection

Connection::Ptr connection

HTTP connection for sending the initial response header.

contentType

std::string contentType

Content-Type of each part (e.g. "image/jpeg").

isBase64

bool isBase64

If true, adds "Content-Transfer-Encoding: base64" to each part.

initial

bool initial

True until the first chunk is processed and the boundary header emitted.

emitter

PacketSignal emitter

Public Methods

Return	Name	Description
	`MultipartAdapter` `inline`	Creates a MultipartAdapter that sends headers through the given connection. The per-part content type is read from the connection's outgoing header.
	`MultipartAdapter` `inline`	Creates a MultipartAdapter that emits its own raw HTTP/1.1 200 response header. Use this when no Connection object is available.
`void`	`emitHeader` `virtual` `inline`	Emits the initial HTTP/1.1 200 OK response with Content-Type multipart/x-mixed-replace. If a connection is set, headers are written through it; otherwise a raw response string is emitted.
`void`	`emitChunkHeader` `virtual` `inline`	Emits the MIME boundary and per-part headers (Content-Type, optionally Content-Transfer-Encoding) for the next multipart chunk.
`void`	`process` `virtual` `inline`	Wraps the incoming packet as a multipart chunk and emits it downstream. Emits the multipart HTTP response headers on the first call.

MultipartAdapter

inline

inline MultipartAdapter(Connection::Ptr connection, bool base64)

Creates a MultipartAdapter that sends headers through the given connection. The per-part content type is read from the connection's outgoing header.

Parameters

connection HTTP connection to use for sending the initial multipart header.
[base64](icy-base64.html#base64) If true, indicates parts are base64-encoded.

MultipartAdapter

inline

inline MultipartAdapter(const std::string & contentType, bool base64)

Creates a MultipartAdapter that emits its own raw HTTP/1.1 200 response header. Use this when no Connection object is available.

Parameters

contentType Content-Type for each multipart part.
[base64](icy-base64.html#base64) If true, indicates parts are base64-encoded.

emitHeader

virtual inline

virtual inline void emitHeader()

Emits the initial HTTP/1.1 200 OK response with Content-Type multipart/x-mixed-replace. If a connection is set, headers are written through it; otherwise a raw response string is emitted.

emitChunkHeader

virtual inline

virtual inline void emitChunkHeader()

Emits the MIME boundary and per-part headers (Content-Type, optionally Content-Transfer-Encoding) for the next multipart chunk.

process

virtual inline

virtual inline void process(IPacket & packet)

Wraps the incoming packet as a multipart chunk and emits it downstream. Emits the multipart HTTP response headers on the first call.

Parameters

packet Packet containing the raw payload data.
