Class: GenericModelEmitter<T>

Defined in: packages/codegen/src/emit/generic-model-emitter.ts:33

Parameterized WholeModelEmitter that wraps any NamespaceEmitter plus a LanguageProfile (019 spec §3.2). Collapses the "per-namespace then aggregate" pattern into one place so individual targets only need to ship a NamespaceEmitter + a Profile.

Dispatch flow:

1. Call the inner NamespaceEmitter for each namespace with suppressBoilerplate: true so shared runtime helpers are emitted once via the Profile's sidecar, not duplicated across per-namespace files.
2. Resolve the layout (defaults to 'barrel' here — the library default of 'per-namespace' is handled one layer up in resolveEmitter before reaching this class).
3. For 'single-file': check the Profile's singleFileLimits, then call concatenate(). Emit a fatal diagnostic if exceeded.
4. For 'barrel': emit per-namespace outputs + the Profile's barrel + the Profile's sidecars.
