Java Serialization Problems, while using guava Lists.transform

Question

I had to serialize a complex object, but one of its component was non-serializable ( a third party graph object), so I created a custom serializable version of this Graph class

Answer 1

Lists.transform() does perform lazily as you suspected. You could do one of

Lists.newArrayList(Lists.transform(...))

or, if you want an immutable version,

ImmutableList.copyOf(Lists.transform(...))

and then serialize the resulting list.
