Nullable adjustable annotations
The compiler means considerably more details away from you to have affiliate details. The latest compiler cannot create assumptions towards acquisition where social members try reached. One societal member was reached in virtually any acquisition. All accessible constructors could be used to initialize the brand new target. When the a member field you are going to ever before be set-to null , the fresh new compiler need to assume their null-state is possibly-null at the outset of each method.
Make use of annotations that will claim whether or not a variable is actually an effective nullable site style of or a non-nullable reference form of. This type of annotations build crucial comments concerning null-state to have details:
- A guide isn’t supposed to be null. The new default condition out of an effective nonnullable reference variable isn’t-null. This new compiler enforces legislation one be sure it’s secure to help you dereference these types of details in the place of earliest checking so it actually null:
- Brand new varying must be initialized so you’re able to a non-null well worth.
- The latest varying cannot be tasked the importance null . „Brand new null-state analysis provides powerful studies for the majority of parameters“ weiterlesen
