## IdCategory class

Mirrors the C++ class of the same name. Each category can have multiple kinds of specializations.

**Signature:**

```typescript
export declare class IdCategory extends StableId 
```
**Extends:** [StableId](./rc-js-util.stableid.md)

## Remarks

There should only be one instance of a conceptual class (which should have a unique name)
