## [Java] Class PackedClosure.Fixed0

- org.codehaus.groovy.runtime.PackedClosure.Fixed0

- All Implemented Interfaces and Traits:
    GeneratedClosure

      public static final class PackedClosure.Fixed0
      extends PackedClosure
      implements GeneratedClosure

  Fixed-arity members of the adapter family: the compiler instantiates the member matching the literal's declared parameter count (FixedN serves higher arities), so a packed closure's arity is visible to class-level introspection exactly as on a generated closure class — notably `MetaClassHelper`'s SAM-overload disambiguation, which reflects the argument class's declared `doCall` and cannot consult the instance. Each member declares ONLY the arity-matched `doCall`(s) (delegating to dispatchAll) and carries the GeneratedClosure marker that introspection keys on, so MOP method selection sees exactly the signatures a generated closure class would declare — in particular, no varargs `doCall(Object[])` that would exact-match a single `Object[]` argument and spread it. The hot entry points remain the base `call` lanes, which do not allocate for these shapes.
