# MessageMedia Utility Classes for Jackson

[![Build Status](https://travis-ci.org/messagemedia/mm-jackson-support.svg?branch=master)](https://travis-ci.org/messagemedia/mm-jackson-support)

This repo contains utility/helper classes for Jackson, a Java JSON library.

## Currently it contains the following modules:

### jackson-support-core

This includes only classes which work with the core Jackson and have no further dependencies.

#### ValueWithNull

This class allows you to distinguish between an explicit null in the JSON and an absent value.

```

public class MyBean {

    @JsonProperty("foobar")

    public ValueWithNull foobar;

    ...

}

```

- JSON ````{}```` => foobar is null

- JSON ````{ "foobar" : null }```` => foobar.isExplicitNull() is true

- JSON ````{ "foobar" : "bla" }```` => foobar.get() returns bla

## Compatibility issues

- Currently there are no known issues with any version other than the specified one in the pom. But please test carefully if you are using another version.

## Installation

### Maven
