Class Base64Codec

    java.lang.Object
      org.apache.cayenne.util.Base64Codec

    public class Base64Codec

extends java.lang.Object

Provides Base64 encoding and decoding as defined by RFC 2045.

This codec is based on Apache commons.codec implementation, copyright The Apache Software Foundation.

Constructor Summary
`Base64Codec()`

Method Summary
`static byte[]` | `decodeBase64(byte[] base64Data)` Decodes Base64 data into octects
`static byte[]` | `encodeBase64(byte[] binaryData)` Encodes binary data using the base64 algorithm but does not chunk the output.
`static byte[]` | `encodeBase64(byte[] binaryData, boolean isChunked)` Encodes binary data using the base64 algorithm, optionally chunking the output into 76 character blocks.
`static byte[]` | `encodeBase64Chunked(byte[] binaryData)` Encodes binary data using the base64 algorithm and chunks the encoded output into 76 character blocks
`static boolean` | `isArrayByteBase64(byte[] arrayOctect)` Tests a given byte array to see if it contains only valid characters within the Base64 alphabet.

Constructor Detail

### Base64Codec

    public Base64Codec()

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

### 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.
