What is a deepClone?
Deep copy, in C#, refers to a technique by which a copy of an object is created such that it contains copies of both instance members and the objects pointed to by reference members. Deep copy is used in scenarios where a new copy (clone) is created without any reference to original data.
What is clone in Apex?
All fields on the SObject are duplicated in memory, including relationship fields. Consequently, if you make changes to a field on the cloned SObject, the original SObject is not affected. If set to false , the method performs a shallow copy of the SObject fields.
What is the difference between shallow cloning and deep cloning in Java?
Shallow Copy stores the references of objects to the original memory address. Deep copy stores copies of the object’s value. Shallow Copy reflects changes made to the new/copied object in the original object. Deep copy doesn’t reflect changes made to the new/copied object in the original object.
Which is better cloning vs Imaging?
Cloning is great for fast recovery, but imaging gives you a lot more backup options. Taking an incremental backup snapshot gives you the option to save multiple images without taking up a lot more space. This can be helpful if you download a virus and need to roll back to an earlier disk image.

Can a deepclone string be cloned to another object?
Unfortunately, deepClone cannot be used with anything that isn’t SObject based. The cloner code must do more. Continuing this example, the values can be cloned too via: Since String instances are immutable there is no harm sharing these between maps/lists/sets/objects. Such an example really should appear in the documentation.
What’s the difference between a root object and a clone?
The “clone” method documentation should describe how just the “root object” is cloned (the object on which clone is called), whilst nested/referenced objects are maintained by reference (and not copied by value), whether these are SObjects or other Apex objects.
