/**
* Wrapper for {@link Builder} that converts {@code null} string arguments to empty strings for

* argument as signal to unset the corresponding field. E.g. for a builder method {@code
* setX(String)} the following semantics apply:
*
*
* - Method is not invoked: X stays unchanged, X is stored as {@code Optional.empty()}.
*
- Argument is a non-empty string Y: X is updated to the Y, X is stored as {@code
* Optional.of(Y)}.
*
- Argument is an empty string: X is unset, X is stored as {@code Optional.of("")}
*
- Argument is {@code null}: X is unset, X is stored as {@code Optional.of("")} (since the
* wrapper converts {@code null} to an empty string)
*
*
* Without the wrapper calling {@code setX(null)} would fail with a {@link
* NullPointerException}. Hence all callers would need to take care to call {@link
* Strings#nullToEmpty(String)} for all string arguments and likely it would be forgotten in
* some places.
*
* This means the stored values are interpreted like this:
*
*
* - {@code Optional.empty()}: property stays unchanged
*
- {@code Optional.of(
)}: property is updated
* - {@code Optional.of("")}: property is unset
*
*
* This wrapper forwards all method invocations to the wrapped {@link Builder} instance that was
* created by AutoValue. For methods that return the AutoValue {@link Builder} instance the
* return value is replaced with the wrapper instance so that all chained calls go through the
* wrapper.
