All Known Implementing Classes:

BeansResolverFactory, MocksResolverFactory, SpringBeansResolverFactory, VariableScopeResolver
```
public interface Resolver
```
A resolver for Objects bound to a key. A resolver provides a set of read only key bindings. This means that key it is not possible to clear a key binding (remove the object bound to the key) or to replace a key binding (set a new object bound to the key).
