#include <icy/http/packetizers.h>

Inherits: PacketProcessor

HTTP chunked transfer encoding adapter for streaming responses.

Public Attributes

Return	Name	Description
`Connection::Ptr`	`connection`	HTTP connection to send the initial response header through.
`std::string`	`contentType`	Content-Type value for the chunked response.
`std::string`	`frameSeparator`	Optional separator written before each chunk payload.
`bool`	`initial`	True until the first chunk is processed and the header emitted.
`bool`	`nocopy`	If true, header/data/footer are emitted as separate packets.
`PacketSignal`	`emitter`

connection

Connection::Ptr connection

HTTP connection to send the initial response header through.

contentType

std::string contentType

Content-Type value for the chunked response.

frameSeparator

std::string frameSeparator

Optional separator written before each chunk payload.

initial

bool initial

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

nocopy

bool nocopy

If true, header/data/footer are emitted as separate packets.

emitter

PacketSignal emitter

Public Methods

Return	Name	Description
	`ChunkedAdapter` `inline`	Creates a ChunkedAdapter that sends its initial response header through the given connection. The content type is read from the connection's outgoing header.
	`ChunkedAdapter` `inline`	Creates a ChunkedAdapter 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 headers with chunked transfer encoding. If a connection is set, headers are written through it; otherwise a raw response string is emitted via the packet signal.
`void`	`process` `virtual` `inline`	Encodes an incoming packet as a chunked transfer encoding chunk and emits it. Emits the HTTP response headers on the first call.

ChunkedAdapter

inline

inline ChunkedAdapter(Connection::Ptr connection, const std::string & frameSeparator, bool nocopy)

Creates a ChunkedAdapter that sends its initial response header through the given connection. The content type is read from the connection's outgoing header.

Parameters

connection HTTP connection to use. May be nullptr to emit a raw response instead.
frameSeparator Optional data prepended to each chunk payload.
nocopy If true, header and payload are emitted as separate packets (avoids copies).

ChunkedAdapter

inline

inline ChunkedAdapter(const std::string & contentType, const std::string & frameSeparator, bool nocopy)

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

Parameters

contentType Content-Type value for the response.
frameSeparator Optional data prepended to each chunk payload.
nocopy If true, header and payload are emitted as separate packets.

emitHeader

virtual inline

virtual inline void emitHeader()

Emits the initial HTTP/1.1 200 OK response headers with chunked transfer encoding. If a connection is set, headers are written through it; otherwise a raw response string is emitted via the packet signal.

process

virtual inline

virtual inline void process(IPacket & packet)

Encodes an incoming packet as a chunked transfer encoding chunk and emits it. Emits the HTTP response headers on the first call.

Parameters

packet Packet containing the raw payload data.

Exceptions

std::invalid_argument if the packet does not carry data.
