      • fallThrough

        public void fallThrough()
        Description copied from interface: Switch
        Enables fall through.

        By default, the fall through is disabled. A case block is treated as a switch rule block; i.e. it's not necessary to add the break statement to prevent the fall through. However, if fall through is enabled then a case block is treated as a labeled statement group; i.e. it's necessary to add the break statement to prevent the fall through.

        For example, if fall through is disabled then: 

         
 StringSwitch s = method.stringSwitch(val);
       s.caseOf(List.of("boom", "foo"), bc -> {...});
        is an equivalent of: 
         switch (val) {
     case "boom", "foo" -> // statements provided by the consumer
 }
        However, if fall though is enabled then: 
         
 StringSwitch s = method.stringSwitch(val);
 s.fallThrough();
 s.caseOf(List.of("boom", "foo"), bc -> {...});
        is an equivalent of: 
         switch (val) {
     case "val1":
     case "val2":
         // statements provided by the consumer
 }
