Function setKnob

setKnob<CONFIG, ID extends string, KNOB extends string>(
    module: KnobTarget<CONFIG>,
    catalogue: readonly KnobEntry<ID>[],
    id: KNOB,
    value: KnobInput<CONFIG, KNOB>,
): void
Sets one knob by its catalogue id, after checking the value with validateKnobValue, and keeps every other setting.
Type Parameters
- CONFIG
- ID extends string
- KNOB extends string
Parameters
- module: KnobTarget<CONFIG>
  A map module, or a plugin with knobs, such as MapEffects.
- catalogue: readonly KnobEntry<ID>[]
  Its knob catalogue, e.g. trafficFlowKnobCatalogue for a TrafficFlowModule.
- id: KNOB
  The knob's id.
- value: KnobInput<CONFIG, KNOB>
Returns void
Remarks
Nothing changes when the value is invalid. A knob's id is its dotted path into the module's configuration, or its key there for StylingFoundationsModule. The change therefore also shows in getConfig and fires a config-change event.

Throws
RangeError for a value the knob does not take; Error for an id the catalogue lacks.
Example
```
setKnob(trafficFlow, trafficFlowKnobCatalogue, 'filters.roadCategories.show', 'only');
setKnob(styling, stylingFoundationsKnobCatalogue, 'labels.sizeFactor', 1.2);
```
