Node

A Node is the smallest composable unit in a SiMa Neat pipeline. Each node contributes deterministic pipeline fragments and metadata used by the builder and runtime.

Reference:

• nodes namespace
• nodes::groups namespace

What a Node represents

• One logical stage in the pipeline (decode, convert, preprocess, sink, etc.).
• A deterministic gst fragment with stable element naming.
• Caps behavior and wiring hints used by Graph build/validation.

Node vs reusable Graph fragment

• Node: single stage.
• Reusable Graph fragment: premade Graph containing an ordered reusable list of nodes (for example input fragments or model stages).

You add both through Graph with add(...).

Why it matters

• Predictable pipeline structure and naming.
• Easier debugging with describe() and describe_backend().
• Reusable building blocks for custom and model-driven flows.
