Let’s say I have a JSON array like:

[
  "item1": {...},
  "item2": {...},
  "item3": {...}
]

What I’d like to do is to find the size in bytes of each item, so for example if item1 was {} that’d be 2.

A way of doing this would be to:

1. Deserialize it into a List<Object>.
2. Serialize each item into a String or byte[].
3. Get the length of each serialized item.

But I’m looking for something more efficient, where I can skip the serialization step.

Deserializing each item into a JSON string would solve this, but I couldn’t find a way of making that work, since it isn’t officially supported.

Any ideas will be appreciated.
