    • toCheckedByteArray

      public static byte[] toCheckedByteArray(CharSequence s)
      Converts the a CharSequence to a byte array, eliminating all the unprintable US-ASCII symbols by replacing them with spaces (' ').
      Parameters:
      s - CharSequence
      Returns:
      a converted byte array, where all the char sequence's unprintable US-ASCII symbols have been replaced with spaces (' ')

    • toCheckedByteArray

      public static byte[] toCheckedByteArray(CharSequence s, byte[] dstArray, int arrayOffs)
      Serializes the passed CharSequence into a passed byte array starting from a given offset. All the unprintable US-ASCII symbols will be replaced with spaces (' ').
      Parameters:
      s - CharSequence
      dstArray - the byte array to be used to convert the CharSequence into
      arrayOffs - the offset in the byte array, where the serialization will be started
      Returns:
      the passed dstArray
      Throws:
      IllegalArgumentException - if there is no enough space in the dstArray to serialize the CharSequence

    • isNonPrintableUsAscii

      public static boolean isNonPrintableUsAscii(int ub)
      Returns true if the passed symbol code represents a non-printable US-ASCII symbol in range [Integer.MIN_VALUE; 9) U (9; 31] U [127; Integer.MAX_VALUE].
      Parameters:
      ub - the symbol code to check
      Returns:
      true if the passed symbol code represents a non-printable US-ASCII symbol in range [Integer.MIN_VALUE; 9) U (9; 31] U [127; Integer.MAX_VALUE]
