      Returns true if given string is null or length is zero.
      static boolean isTrimmedEmpty​(java.lang.String str)
      This is equal to str.trim().isEmpty(), but avoids temporary trimmed substring allocation.

        Returns true if given string is null or length is zero.

      • removeLeading

        public static java.lang.String removeLeading​(java.lang.String string,
                                             java.lang.String leading)

                                                     char delim)

      • split

        public static java.util.List<java.lang.String> split​(java.lang.String str,
                                                     char delim,

                                                     boolean excludeEmpty)
        Splits a string at the specified delimiter. If trimming is enabled, then leading and trailing whitespace characters are removed. If excludeEmpty is true, then only non-empty strings are returned.

      • add

        private static void add​(java.util.List<java.lang.String> strs,
                        java.lang.String str,

                                                int beginIndex)
        This is equal to str.substring( beginIndex, endIndex ).trim(), but avoids temporary untrimmed substring allocation. If the trimmed string is empty, a shared empty string is returned.
        Since:
        2

        This is equal to str.substring( beginIndex ).trim(), but avoids temporary untrimmed substring allocation. If the trimmed string is empty, a shared empty string is returned.
        Since:
        2

      • isTrimmedEmpty

        public static boolean isTrimmedEmpty​(java.lang.String str)
