Method Detail

deserialize

public static Object deserialize(String s,
                                 boolean gzip)
                          throws IOException,
                                 ClassNotFoundException

Read the object from Base64 string.

Parameters:

s - the string representation of serialized object.

gzip - if gzip stream

Returns:

the deserialize object

Throws:

IOException - if any io pb

ClassNotFoundException - if class not found ?

serialize

public static String serialize(Object o,
                               boolean gzip)
                        throws IOException

Write the object to a Base64 string.

Parameters:

o - the object to serialize

gzip - if gzip stream

Returns:

the string representation

Throws:

IOException - if any io pb

encodeString

public static String encodeString(String s)

Encodes a string into Base64 format. No blanks or line breaks are inserted.

Parameters:

s - a String to be encoded.

Returns:

A String with the Base64 encoded data.

encode

public static char[] encode(byte[] in)

Encodes a byte array into Base64 format. No blanks or line breaks are inserted.

Parameters:

in - an array containing the data bytes to be encoded.

Returns:

A character array with the Base64 encoded data.

encode

public static char[] encode(byte[] in,
                            int iLen)

Encodes a byte array into Base64 format. No blanks or line breaks are inserted.

Parameters:

in - an array containing the data bytes to be encoded.

iLen - number of bytes to process in in.

Returns:

A character array with the Base64 encoded data.

decodeString

public static String decodeString(String s)

Decodes a string from Base64 format.

Parameters:

s - a Base64 String to be decoded.

Returns:

A String containing the decoded data.

Throws:

IllegalArgumentException - if the input is not valid Base64 encoded data.

decode

public static byte[] decode(String s)

Decodes a byte array from Base64 format.

Parameters:

s - a Base64 String to be decoded.

Returns:

An array containing the decoded data bytes.

Throws:

IllegalArgumentException - if the input is not valid Base64 encoded data.

decode

public static byte[] decode(char[] in)

Decodes a byte array from Base64 format. No blanks or line breaks are allowed within the Base64 encoded data.

Parameters:

in - a character array containing the Base64 encoded data.

Returns:

An array containing the decoded data bytes.

Throws:

IllegalArgumentException - if the input is not valid Base64 encoded data.
