Meaning of the annotations for the proof of each method:
- local_polyh: uses a local linear ranking function for the binary unfolding with polyhedra
- local_mono: uses a local linear ranking function for the binary unfolding with monotonicity constraints
- global_affrnkfn: uses a global affine ranking function with polyhedra
- numerical: the ranking function uses numerical variables or fields
- structural: the ranking function uses reference variables or fields
- loop: the method seems to be part of a loop or recursion

All calls to these methods terminate:
[loop,numerical,local_polyh]                 public List.(int):void
[loop,structural,local_polyh]                public static Test4.main(java.lang.String[]):void
                                             public List.(java.lang.Object,List):void
[loop,structural,local_polyh]                private static Test4.length(List):int
                                             public List.getTail():List

Some calls to these methods might not terminate:
  none
