additional null-checking apis for locking?

[hrstoyanov]

Is your feature request related to a problem? Please describe.

With lockers one can do this:

class Store extends StripeLockScope {

    private static final IndexerLong ID_INDEXEER = ...;
    private GigaMap map = ... ;
     
    void doSomething(UUID entityId){
         read(entityId, ()->{
                var e = map.query(ID_INDEXER.is(entityId)).findFirst();
                ...
          });
  }
}

if the entityId input is NULL the query would have still worked , but the read lock will cause NullPointerException, so one need to guard with a null check:

   if(entityId!=null){
        read(...);
   }
    

This quickly becomes noise/boring, if you have a lot of these apis .

Describe the solution you'd like

Add to StripeLockScope/ReadWriteLocked/etc. null-checking apis.

Describe alternatives you've considered

Take a look at the attached workaround I currently use - something like this could become part of EclipseStore core?
