IOException - thrown if error

deSerialize

public static <T> T deSerialize(byte[] array)
                         throws IOException,
                                ClassNotFoundException

Deserialise based on byte array to object

deepClone

public static <T> T deepClone(T object)

clone an object by using the serialise/deserialise methods in this class. This is a costly operation

Type Parameters:

T - object type

Parameters:

object - to clone

Returns:

cloned version

deepCloneFromTo

public static <K,V> Map<K,V> deepCloneFromTo(Map<K,V> sourceMap,
                                                         Map<K,V> destinationMap)

clone object values (not keys) in source map by using the serialise/deserialise methods in this class. This is a costly operation

Type Parameters:

K - key type

V - object value type

Parameters:

sourceMap - to clone

destinationMap - to populate

Returns:

destination map
