Method Details

deserializeFromBase64

public static Map<String,? extends Serializable> deserializeFromBase64(String rawString)
                                                                throws IOException

Deserializes a Base64-encoded String into a HashMap. Both the keys and values must implement Serializable.

Parameters:

rawString - the String contents containing the map to be deserialized

Returns:

the attributes, parsed into a Map

Throws:

IOException - if the contents cannot be parsed for any reason

serializeToBase64

public static String serializeToBase64(Map<String,Serializable> map)
                                throws IOException

Serializes a Map and formats it into a Base64-encoded String. For ease of serialization, the Map contents are first copied into a HashMap, then serialized into a byte array that is encoded as a Base64 String.

Parameters:

map - the Map to serialize

Returns:

a String representing the serialized form of the Map

Throws:

IOException - If serialization cannot be done
