Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface HasHashIndex
Interface for types with a hash index; this is used to seed the hashcode computation for instances, so that the hashcodes of objects with different types are /more/ different than the hashcodes of objects with the same type. One application is ensuring that punned entities do not have clashing hashcodes.

  • Method Details

    • hashIndex

      int hashIndex()
      Returns:
      index for this type. This is not a hashcode for instances, rather a hashcode for the types.
