## org.ajax4jsf.util.base64
Class URL64Codec

    java.lang.Object
      org.ajax4jsf.util.base64.URL64Codec

All Implemented Interfaces:
  BinaryDecoder, BinaryEncoder, Decoder, Encoder

    public class URL64Codec

extends Object
implements BinaryEncoder, BinaryDecoder

Provides Base64 encoding and decoding like defined by RFC 2045, but with little difference : chars '=' '+' and '/' , incorrectly processed in URL by any browsers, replaced by '_' '-' '!',

Since:
  1.0-dev

Method Summary
`byte[]` | `decode(byte[] pArray)` Decodes a byte[] containing containing characters in the Base64 alphabet.
`Object` | `decode(Object pObject)` Decodes an Object using the base64 algorithm.
`static byte[]` | `decodeBase64(byte[] base64Data)` Decodes Base64 data into octects
`byte[]` | `encode(byte[] pArray)` Encodes a byte[] containing binary data, into a byte[] containing characters in the Base64 alphabet.
`Object` | `encode(Object pObject)` Encodes an Object using the base64 algorithm.
`static byte[]` | `encodeBase64(byte[] binaryData)` Encodes binary data using the base64 algorithm but does not chunk the output.

Constructor Detail

### URL64Codec

    public URL64Codec()

Method Detail

### isArrayByteBase64

    public static boolean isArrayByteBase64(byte[] arrayOctect)

  Tests a given byte array to see if it contains only valid characters within the Base64 alphabet.

  Parameters:
    `arrayOctect` - byte array to test
  Returns:
    true if all bytes are valid characters in the Base64 alphabet or if the byte array is empty; false, otherwise

### encodeBase64

    public static byte[] encodeBase64(byte[] binaryData)

  Encodes binary data using the base64 algorithm but does not chunk the output.

  Parameters:
    `binaryData` - binary data to encode
  Returns:
    Base64 characters

### encodeBase64Chunked

    public static byte[] encodeBase64Chunked(byte[] binaryData)

  Encodes binary data using the base64 algorithm and chunks the encoded output into 76 character blocks

  Parameters:
    `binaryData` - binary data to encode
  Returns:
    Base64 characters chunked in 76 character blocks

### decode

    public Object decode(Object pObject)
                  throws DecoderException

  Decodes an Object using the base64 algorithm. This method is provided in order to satisfy the requirements of the Decoder interface, and will throw a DecoderException if the supplied object is not of type byte[].

  Specified by:
    `decode` in interface `Decoder`
  Parameters:
    `pObject` - Object to decode
  Returns:
    An object (of type byte[]) containing the binary data which corresponds to the byte[] supplied.
  Throws:
    `DecoderException` - if the parameter supplied is not of type byte[]

### decode

    public byte[] decode(byte[] pArray)

  Decodes a byte[] containing containing characters in the Base64 alphabet.

  Specified by:
    `decode` in interface `BinaryDecoder`
  Parameters:
    `pArray` - A byte array containing Base64 character data
  Returns:
    a byte array containing binary data

### encodeBase64

    public static byte[] encodeBase64(byte[] binaryData,
                                      boolean isChunked)

  Encodes binary data using the base64 algorithm, optionally chunking the output into 76 character blocks.

  Parameters:
    `binaryData` - Array containing binary data to encode.
    `isChunked` - if isChunked is true this encoder will chunk the base64 output into 76 character blocks
  Returns:
    Base64-encoded data.

### decodeBase64

    public static byte[] decodeBase64(byte[] base64Data)

  Decodes Base64 data into octects

  Parameters:
    `base64Data` - Byte array containing Base64 data
  Returns:
    Array containing decoded data.

### encode

    public Object encode(Object pObject)
                  throws EncoderException

  Encodes an Object using the base64 algorithm. This method is provided in order to satisfy the requirements of the Encoder interface, and will throw an EncoderException if the supplied object is not of type byte[].

  Specified by:
    `encode` in interface `Encoder`
  Parameters:
    `pObject` - Object to encode
  Returns:
    An object (of type byte[]) containing the base64 encoded data which corresponds to the byte[] supplied.
  Throws:
    `EncoderException` - if the parameter supplied is not of type byte[]

### encode

    public byte[] encode(byte[] pArray)

  Encodes a byte[] containing binary data, into a byte[] containing characters in the Base64 alphabet.

  Specified by:
    `encode` in interface `BinaryEncoder`
  Parameters:
    `pArray` - a byte array containing binary data
  Returns:
    A byte array containing only Base64 character data
