Method Detail

encodeBytes

public static java.lang.String encodeBytes(byte[] source)

Encodes a byte array into Base64 notation.

Parameters:

source - The data to convert

Since:

1.4

encodeBytes

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

Encodes a byte array into Base64 notation.

Valid options:

   DONT_BREAK_LINES: don't break lines at 76 characters
     Note: Technically, this makes your encoding non-compliant.
 

Example: encodeBytes( myData, Base64.GZIP ) or

Example: encodeBytes( myData, Base64.GZIP | Base64.DONT_BREAK_LINES )

Parameters:

source - The data to convert

off - Offset in array where conversion should begin

len - Length of data to convert

Returns:

the encoded content as string

Since:

2.0

decode

public static byte[] decode(byte[] source,
                            int off,
                            int len)
                     throws MXQueryException

Very low-level access to decoding ASCII characters in the form of a byte array.

Parameters:

source - The Base64 encoded data

off - The offset of where to begin decoding

len - The length of characters to decode

Returns:

decoded data

Throws:

MXQueryException

Since:

1.3

decode

public static byte[] decode(java.lang.String s)
                     throws MXQueryException

Decodes data from Base64 notation

Parameters:

s - the string to decode

Returns:

the decoded data

Throws:

MXQueryException

Since:

1.4
