Method Detail

• encodeBase64

  public static Writable encodeBase64​(Byte[] data,
                                      boolean chunked)

  Produce a Writable object which writes the Base64 encoding of the byte array. Calling toString() on the result returns the encoding as a String. For more information on Base64 encoding and chunking see RFC 4648.

  Parameters:

  data - Byte array to be encoded

  chunked - whether or not the Base64 encoded data should be MIME chunked

  Returns:

  object which will write the Base64 encoding of the byte array

  Since:

  1.5.1

• encodeBase64

  public static Writable encodeBase64​(Byte[] data)

  Produce a Writable object which writes the Base64 encoding of the byte array. Calling toString() on the result returns the encoding as a String. For more information on Base64 encoding and chunking see RFC 4648.

  Parameters:

  data - Byte array to be encoded

  Returns:

  object which will write the Base64 encoding of the byte array

  Since:

  1.0

• encodeBase64

  public static Writable encodeBase64​(byte[] data,
                                      boolean chunked)

  Produce a Writable object which writes the Base64 encoding of the byte array. Calling toString() on the result returns the encoding as a String. For more information on Base64 encoding and chunking see RFC 4648.

  Parameters:

  data - byte array to be encoded

  chunked - whether or not the Base64 encoded data should be MIME chunked

  Returns:

  object which will write the Base64 encoding of the byte array

  Since:

  1.5.7

• encodeBase64

  public static Writable encodeBase64​(byte[] data)

  Produce a Writable object which writes the Base64 encoding of the byte array. Calling toString() on the result returns the encoding as a String. For more information on Base64 encoding and chunking see RFC 4648.

  Parameters:

  data - byte array to be encoded

  Returns:

  object which will write the Base64 encoding of the byte array

  Since:

  1.0

• decodeBase64

  public static byte[] decodeBase64​(String value)

  Decode the String from Base64 into a byte array.

  Parameters:

  value - the string to be decoded

  Returns:

  the decoded bytes as an array

  Since:

  1.0

• encodeHex

  public static Writable encodeHex​(Byte[] data)

  Produces a Writable that writes the hex encoding of the Byte[]. Calling toString() on this Writable returns the hex encoding as a String. The hex encoding includes two characters for each byte and all letters are lower case.

  Parameters:

  data - byte array to be encoded

  Returns:

  object which will write the hex encoding of the byte array

  See Also:

  Integer.toHexString(int)

• encodeHex

  public static Writable encodeHex​(byte[] data)

  Produces a Writable that writes the hex encoding of the byte[]. Calling toString() on this Writable returns the hex encoding as a String. The hex encoding includes two characters for each byte and all letters are lower case.

  Parameters:

  data - byte array to be encoded

  Returns:

  object which will write the hex encoding of the byte array

  See Also:

  Integer.toHexString(int)

• decodeHex

  public static byte[] decodeHex​(String value)

  Decodes a hex string to a byte array. The hex string can contain either upper case or lower case letters.

  Parameters:

  value - string to be decoded

  Returns:

  decoded byte array

  Throws:

  NumberFormatException - If the string contains an odd number of characters or if the characters are not valid hexadecimal values.
