What's the opposite of 'clone'?

Question

I have a class that implements ICloneable. I need it to have a backup of an entity, so when the user clicks cancel, etc., I have all values asides.

I want to create in the cloneable class another function, that clones in, i.e. receives another class of the same type and uses the same clone but to the opposite direction while the other members are still the same, i.e. the instance is the same.

How should I name that function?

I would say my question is what's the opposite of 'Clone' something like 'swallow' etc., you're the expert, I don't know English.

Thanks

Answer 1

How about Merge?

Answer 2

CopyFrom?

Answer 3

Restore, I'd say. The backup/restore metaphor applies.

Answer 4

ThereCanBeOnlyOne()?

Answer 5

In Java, we have String.intern() to do as you want. So maybe Interner makes sense. Guava will also use this term, I believe.

Answer 6

Compose may also work for the opposite of clone.

Answer 7

What about Absorb?
