JSON Tuple Databinding Examples

Usually, logical records/structs are encoded as JSON objects. For example, a search API might return:

{
    "elapsed": 321000,
    "entries": [
        {"name": "Manifesto.txt", "metadata": {"size": 914235, "date": "2014-01-12"}},
        {"name": ".bashrc", "metadata": {"size": 670, "date": "2010-09-28"}}
    ]
}

If you define classes for each of the structures, JSON libraries with databinding support can automatically create object instances for you.

But lets say that instead of using a JSON object for each element of "entries", the search API returned a tuple-like representation using JSON arrays:

{
    "elapsed": 321000,
    "entries": [
        ["Manifesto.txt", {"size": 914235, "date": "2014-01-12"}],
        [".bashrc", {"size": 670, "date": "2010-09-28"}]
    ]
}

JSON libraries with automatic databinding won't know how to convert each tuple into an Entry object.

This repo has code that shows you how to get tuples to work for different JSON libraries:

Java:

• Jackson - JacksonEntryCustomizer.java
• Gson - GsonEntryCustomizer.java
