static byte[] |
decode(byte[] source,
int off,
int len) |
Very low-level access to decoding ASCII characters in the form of a byte array.
|
static byte[] |
decode(java.lang.String s) |
Decodes data from Base64 notation, automatically detecting gzip-compressed data and
decompressing it.
|
static java.lang.String |
encodeBytes(byte[] source) |
Encodes a byte array into Base64 notation.
|
static java.lang.String |
encodeBytes(byte[] source,
int options) |
Encodes a byte array into Base64 notation.
|
static java.lang.String |
encodeBytes(byte[] source,
int off,
int len) |
Encodes a byte array into Base64 notation.
|
static java.lang.String |
encodeBytes(byte[] source,
int off,
int len,

- The data to convertpublic static java.lang.String encodeBytes(byte[] source, int options)
Valid options:
GZIP: gzip-compresses object before encoding it. DONT_BREAK_LINES: don't break lines at 76 characters Note: Technically, this makes your encoding non-compliant.
Example: encodeBytes( myData, Base64.GZIP )
or
