8.2 Node Mapping Principles

Go To Mapping from FX Logical Nodes to Implementation Artifacts

The Phase 0 Implementation Profile applies the following principles when mapping FX logical Nodes to implementation artifacts.

Each implementation Node artifact identifies:

• the FX logical Node or Nodes it realizes;
• the FX logical Node Role or Node Roles it performs;
• the Runtime Plane or Runtime Planes it supports;
• the DDS Topics, IDL structures, generated types, configuration artifacts, scripts, and supporting modules it uses;
• the relevant Part 3 FX logical Node definition;
• the applicable Phase 0 Developer Handbook rules; and
• the observable behavior required by the Phase 0 logging and exception-handling baseline.

The mapping does not require one-to-one correspondence between logical Nodes and runtime artifacts. A single runtime artifact may realize multiple FX logical Nodes. Multiple implementation artifacts may realize one FX logical Node. The mapping table records the selected Phase 0 choice.
