Detailed Description

In-place inverter for SLAC AXI Batcher v2 framing.

Protocol reference: https://confluence.slac.stanford.edu/x/L2VlK

InverterV2 uses CoreV2 metadata to reinterpret/shift record tail data inside the original frame payload. This produces a transformed frame layout expected by downstream consumers without allocating one frame per record. It is not a batching or unbatching stage: one input frame yields one output frame after in-place reformatting.

InverterV2 transforms a batcher v2 frame by copying per-record tail fields into the header/tail positions expected by downstream consumers and trimming the final tail from payload. The transformed frame is then forwarded. Use SplitterV2 when true unbatching (one output frame per record) is desired.

Threading model:

No internal worker thread is created.
Processing executes synchronously in the caller thread of acceptFrame().

Constructor & Destructor Documentation

◆ InverterV2()

rogue::protocols::batcher::InverterV2::InverterV2 ( )

Constructs an InverterV2 instance.

Creator.

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

Definition at line 61 of file InverterV2.cpp.

◆ ~InverterV2()

rogue::protocols::batcher::InverterV2::~InverterV2 ( )

Destroys the inverter.

Deconstructor.

Definition at line 64 of file InverterV2.cpp.

Member Function Documentation

◆ acceptFrame()

void rogue::protocols::batcher::InverterV2::acceptFrame ( std::shared_ptr< rogue::interfaces::stream::Frame > frame )

virtual

Accepts, transforms, and forwards one batcher v2 frame.

Accept a frame from master.

Parameters

frame Input frame to transform.

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

Definition at line 67 of file InverterV2.cpp.

◆ create()

rogue::protocols::batcher::InverterV2Ptr rogue::protocols::batcher::InverterV2::create ( )

static

Creates an InverterV2 instance.

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 inverter.

Company : SLAC National Accelerator Laboratory
