UnreferencedShapes (Smithy API 1.50.0)

java.lang.Object
- software.amazon.smithy.model.neighbor.UnreferencedShapes

```
public final class UnreferencedShapes
extends java.lang.Object
```
Finds shapes that are not connected to a "root" shape, are not trait definitions, are not referenced by trait definitions, and are not referenced in trait values through IdRefTrait.
The "root" shapes defaults to all service shapes in the model. You can customize this by providing a selector that considers every matching shape a root shape. For example, a model might consider all shapes marked with a trait called "root" to be a root shape.
Prelude shapes are never considered unreferenced.
