 You can express nullability constraints for repository methods by using {spring-framework-docs}/core.html#null-safety[Spring Framework's nullability annotations].
 They provide a tooling-friendly approach and opt-in `null` checks during runtime, as follows:
 
-* {spring-framework-javadoc}/org/springframework/lang/NonNullApi.html[`@NonNullApi`]: Used on the package level to declare that the default behavior for parameters and return values is to not accept or produce `null` values.
+* {spring-framework-javadoc}/org/springframework/lang/NonNullApi.html[`@NonNullApi`]: Used on the package level to declare that the default behavior for parameters and return values is, respectively, neither to accept nor to produce `null` values.
 * {spring-framework-javadoc}/org/springframework/lang/NonNull.html[`@NonNull`]: Used on a parameter or return value that must not be `null` (not needed on a parameter and return value where `@NonNullApi` applies).
 * {spring-framework-javadoc}/org/springframework/lang/Nullable.html[`@Nullable`]: Used on a parameter or return value that can be `null`.

 Once non-null defaulting is in place, repository query method invocations get validated at runtime for nullability constraints.
 If a query result violates the defined constraint, an exception is thrown. This happens when the method would return `null` but is declared as non-nullable (the default with the annotation defined on the package in which the repository resides).
 If you want to opt-in to nullable results again, selectively use `@Nullable` on individual methods.
-Using the result wrapper types mentioned at the start of this section continues to work as expected: An empty result is translated into the value that represents absence.
