deepCopy

public static Object deepCopy(Object original,
                              Serializer serializer)

Produce a deep copy of the given object. Serializes the entire object to a byte array in memory. Recommended for relatively small objects, such as individual transactions.

deepCopyParallel

public static Object deepCopyParallel(Object original,
                                      Serializer serializer)
                               throws Exception

Produce a deep copy of the given object. Serializes the object through a pipe between two threads. Recommended for very large objects, such as an entire prevalent system. The current thread is used for serializing the original object in order to respect any synchronization the caller may have around it, and a new thread is used for deserializing the copy.

Throws:

Exception
