Detailed Description

Packetizer transport endpoint.

Bridges raw stream traffic to/from the packetizer controller.

Threading model:

Inbound frames are handled synchronously by acceptFrame(), which forwards each frame to Controller::transportRx().
Outbound frames are produced by a dedicated background thread started in setController(). That thread drains Controller::transportTx() and forwards returned frames via sendFrame().

Lifetime contract:

setController() must be called before destruction so the TX queue thread can be started/stopped against a valid controller.

Constructor & Destructor Documentation

◆ Transport()

rogue::protocols::packetizer::Transport::Transport ( )

Constructs a packetizer transport endpoint.

Creator.

This constructor is a low-level C++ allocation path. Prefer create() when shared ownership or Python exposure is required.

Definition at line 56 of file Transport.cpp.

◆ ~Transport()

rogue::protocols::packetizer::Transport::~Transport ( )

Destroys the packetizer transport endpoint.

Destructor.

Definition at line 59 of file Transport.cpp.

Member Function Documentation

◆ acceptFrame()

void rogue::protocols::packetizer::Transport::acceptFrame ( std::shared_ptr< rogue::interfaces::stream::Frame > frame )

virtual

Accepts a frame from the upstream stream interface.

Accept a frame from master.

Parameters

frame Input frame to decode and forward to controller logic.

Reimplemented from rogue::interfaces::stream::Slave.

Definition at line 80 of file Transport.cpp.

◆ create()

rogue::protocols::packetizer::TransportPtr rogue::protocols::packetizer::Transport::create ( )

static

Creates a packetizer transport endpoint.

Class creation.

This static factory is the preferred construction path when the object is shared across Rogue graph connections or exposed to Python. It returns std::shared_ptr ownership compatible with Rogue pointer typedefs.

Returns: Shared pointer to the created transport endpoint.

Setup links.

Stores the controller reference and starts the outbound worker thread that forwards controller-generated transport frames.

Parameters

cntl	Controller instance that handles packetizer protocol processing.
