Method Summary

Modifier and Type	Method and Description
static String	encode(String string) Encode string as a byte array in Base64 annotation.
static String	encodeBytes(byte[] source) Encodes a byte array into Base64 notation.
static String	encodeBytes(byte[] source, int off, int len) Encodes a byte array into Base64 notation.
static byte[]	encodeBytesToBytes(byte[] source, int off, int len) Similar to encodeBytes(byte[], int, int) but returns a byte array instead of instantiating a String.

Method Detail

encode

public static String encode(String string)

Encode string as a byte array in Base64 annotation.

Parameters:

string -

Returns:

The Base64-encoded data as a string

encodeBytes

public static String encodeBytes(byte[] source)

Encodes a byte array into Base64 notation.

Parameters:

source - The data to convert

Returns:

The Base64-encoded data as a String

Throws:

NullPointerException - if source array is null

IllegalArgumentException - if source array, offset, or length are invalid

Since:

2.0

encodeBytes

public static String encodeBytes(byte[] source,
                                 int off,
                                 int len)

Encodes a byte array into Base64 notation.

Parameters:

source - The data to convert

off - Offset in array where conversion should begin

len - Length of data to convert

Returns:

The Base64-encoded data as a String

Throws:

NullPointerException - if source array is null

IllegalArgumentException - if source array, offset, or length are invalid

Since:

2.0

encodeBytesToBytes

public static byte[] encodeBytesToBytes(byte[] source,
                                        int off,
                                        int len)

Similar to encodeBytes(byte[], int, int) but returns a byte array instead of instantiating a String. This is more efficient if you're working with I/O streams and have large data sets to encode.

Parameters:

source - The data to convert

off - Offset in array where conversion should begin

len - Length of data to convert

Returns:

The Base64-encoded data as a String if there is an error

Throws:

NullPointerException - if source array is null

IllegalArgumentException - if source array, offset, or length are invalid

Since:
