Detailed Description

This class extract files from FLUTE streams in UDP datagrams.

Member Typedef Documentation

SessionStatus

using ts::mcast::FluteDemux::SessionStatus = std::map<FluteSessionId, std::map<UString, FileStatus>>

Description of all files, in all sessions, as returned by getFilesStatus(). The outer map is indexed by FLUTE session id. In each session, the files are indexed by name.

Constructor & Destructor Documentation

FluteDemux()

ts::mcast::FluteDemux::FluteDemux ( DuckContext & duck, FluteHandlerInterface * handler = nullptr )

explicit

Constructor.

Parameters

[in,out]	duck	TSDuck execution context. The reference is kept inside the demux.
[in]	handler	The object to invoke when FLUTE information is found.

~FluteDemux()

ts::mcast::FluteDemux::~FluteDemux

(

)

Destructor.

Member Function Documentation

setHandler()

void ts::mcast::FluteDemux::setHandler ( FluteHandlerInterface * h )

inline

Replace the FLUTE handler.

Parameters

[in]

h

The new handler.

reset()

bool ts::mcast::FluteDemux::reset	(	const FluteDemuxArgs &	args,
		bool	will_get_files_status = false )

Reset the demux.

Parameters

[in]	args	Demux arguments.
[in]	will_get_files_status	We intend to call getFilesStatus() later. This means that the demux needs to keep track of all received files. Since this uses a ever-growing amount of memory, be sure to specify this option when necessary only and when the demux session, until the next reset(), is limited in time.

Returns

True on success, false on error.

feedPacket() [1/2]

template<class Rep, class Period>

void ts::mcast::FluteDemux::feedPacket	(	const cn::duration< Rep, Period > &	timestamp,
		const IPPacket &	pkt )

The following method feeds the demux with an IP packet. The packet is ignored if this is not a UDP packet.

Parameters

[in]	timestamp	Packet time stamp value. This value should be taken from a monotonic clock.
[in]	pkt	An IP packet.

feedPacket() [2/2]

template<class Rep, class Period>

void ts::mcast::FluteDemux::feedPacket ( const cn::duration< Rep, Period > & timestamp, const IPSocketAddress & source, const IPSocketAddress & destination, const uint8_t * udp, size_t udp_size )

inline

The following method feeds the demux with a UDP packet.

Parameters

[in]	timestamp	Packet time stamp value. This value should be taken from a monotonic clock.
[in]	source	Source socket address.
[in]	destination	Destination socket address.
[in]	udp	Address of UDP payload.
[in]	udp_size	Size in bytes of UDP payload.

getFilesStatus()

void ts::mcast::FluteDemux::getFilesStatus

(

SessionStatus &

status

)

const

Get the current status of all file transfers. This method returns current transfers only if will_get_files_status was false when reset() was called.

Parameters

[out]

status

A description of all sessions and files.

printFilesStatus()

void ts::mcast::FluteDemux::printFilesStatus

(

std::ostream &

out

)

const

Print a list of all received files. This method prints current transfers only if will_get_files_status was false when reset() was called.

Parameters

[in,out]

out

Where to print the summary.
