With this, we get tooling support, from editors and mypy as this code is correct in terms of types, but we also get the data filtering from FastAPI.

How does this work? Let's check that out. 🤓

### Type Annotations and Tooling { #type-annotations-and-tooling }

First let's see how editors, mypy and other tools would see this.

    final ChainingCalls delegate;

    ForwardingChainingCalls(ChainingCalls delegate) {
      this.delegate = delegate;
    }

    @CanIgnoreReturnValue
    @Override

      delegate.chainingCall();
      return this;
    }

    @Override
    public ChainingCalls nonChainingCall() {
      return delegate.nonChainingCall();
    }
