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:
                                             public static Infix2Postfix.main(java.lang.String[]):void
                                             public LinkedList.getTail():LinkedList
                                             public LinkedList.(char,LinkedList):void
[loop,numerical,structural,local_polyh]      public static Infix2Postfix.buildExpression(int):LinkedList
[loop,structural,local_polyh]                public static Infix2Postfix.toPostfix(LinkedList):LinkedList
                                             public LinkedList.getFirst():char

Some calls to these methods might not terminate:
  none
There are no warnings
