Package org.axonframework.common.nullability

@NullMarked package org.axonframework.common.nullability

Resolution of the nullability declared for a method or constructor parameter.

Annotations are only one way a language expresses nullability, which is why this lives beside rather than inside the annotation utilities. Kotlin, for one, encodes it in its type system. The NullabilityResolver service interface lets such languages contribute resolution the framework cannot perform on its own.
