        public static StringSwitcher create​(java.lang.String[] strings,
                                            int[] ints,
                                            boolean fixedInput)
        Helper method to create a StringSwitcher. For finer control over the generated instance, use a new instance of StringSwitcher.Generator instead of this static method.
        Parameters:
        strings - the array of String keys; must be the same length as the value array
        ints - the array of integer results; must be the same length as the key array
        fixedInput - if false, an unknown key will be returned from intValue(java.lang.String) as -1; if true, the result will be undefined, and the resulting code will be faster
      • intValue

        public abstract int intValue​(java.lang.String s)
        Return the integer associated with the given key.
        Parameters:
        s - the key
        Returns:
        the associated integer value, or -1 if the key is unknown (unless fixedInput was specified when this StringSwitcher was created, in which case the return value for an unknown key is undefined)
