      Modifier and Type Method Description
      static byte[] getBytesUnchecked​(java.lang.String string, java.lang.String charsetName)
      Encodes the given string into a sequence of bytes using the named charset, storing the result into a new byte array.
      static byte[] getBytesUtf8​(java.lang.String string)
      Encodes the given string into a sequence of bytes using the UTF-8 charset, storing the result into a new byte array.
      static java.lang.String newString​(byte[] bytes, java.lang.String charsetName)
      Constructs a new String by decoding the specified array of bytes using the given charset.
      static java.lang.String newStringUtf8​(byte[] bytes)
      Constructs a new String by decoding the specified array of bytes using the UTF-8 charset.

      • newString

        public static java.lang.String newString​(byte[] bytes,
                                         java.lang.String charsetName)
        Constructs a new String by decoding the specified array of bytes using the given charset.

        This method catches UnsupportedEncodingException and re-throws it as IllegalStateException, which should never happen for a required charset name. Use this method when the encoding is required to be in the JRE.

        Parameters:
        bytes - The bytes to be decoded into characters
        charsetName - The name of a required Charset
        Returns:
        A new String decoded from the specified array of bytes using the given charset.
        Throws:
        java.lang.IllegalStateException - Thrown when a UnsupportedEncodingException is caught, which should never happen for a required charset name.

      • newStringUtf8

        public static java.lang.String newStringUtf8​(byte[] bytes)
        Constructs a new String by decoding the specified array of bytes using the UTF-8 charset.
        Parameters:
        bytes - The bytes to be decoded into characters
        Returns:
        A new String decoded from the specified array of bytes using the given charset.
        Throws:
        java.lang.IllegalStateException - Thrown when a UnsupportedEncodingException is caught, which should never happen since the charset is required.

      • getBytesUtf8

        public static byte[] getBytesUtf8​(java.lang.String string)
        Encodes the given string into a sequence of bytes using the UTF-8 charset, storing the result into a new byte array.
        Parameters:
        string - the String to encode
        Returns:
        encoded bytes
        Throws:
        java.lang.IllegalStateException - Thrown when the charset is missing, which should be never according the the Java specification.

      • getBytesUnchecked

        public static byte[] getBytesUnchecked​(java.lang.String string,
                                       java.lang.String charsetName)
        Encodes the given string into a sequence of bytes using the named charset, storing the result into a new byte array.

        This method catches UnsupportedEncodingException and rethrows it as IllegalStateException, which should never happen for a required charset name. Use this method when the encoding is required to be in the JRE.

        Parameters:
        string - the String to encode
        charsetName - The name of a required Charset
        Returns:
        encoded bytes
        Throws:
        java.lang.IllegalStateException - Thrown when a UnsupportedEncodingException is caught, which should never happen for a required charset name.
