Fabulous fork

This fork is a copy of the original Gson repository with the following changes:

• FieldNamingStrategy interface has a new default method translateNameWithAlternatives() that can be overridden so that we can create a universal deserializer which supports camelCase and snake_case naming conventions when deserializing
• ReflectiveTypeAdapterFactory uses fieldNamingPolicy.translateNameWithAlternatives() to consider alternative json field names when deserializing
• updated source version to 1.8
• added dependency to com.google.j2objc:j2objc-annotations:1.3 and used @Weak and @WeakOuter annotations to avoid memory leaks in j2objc

Building gson and using it in Fabulous Core project

1. Gson is built using maven. Run the following command to build the project:

   mvn source:jar package

2. this will create a gson-2.8.8.jar and gson-2.8.9-sources.jar files in the target directory
3. copy the above files to fabulous-core/libs/ directory in the Fabulous Core project

Gson

Gson is a Java library that can be used to convert Java Objects into their JSON representation. It can also be used to convert a JSON string to an equivalent Java object. Gson can work with arbitrary Java objects including pre-existing objects that you do not have source-code of.

There are a few open-source projects that can convert Java objects to JSON. However, most of them require that you place Java annotations in your classes; something that you can not do if you do not have access to the source-code. Most also do not fully support the use of Java Generics. Gson considers both of these as very important design goals.

Goals

• Provide simple toJson() and fromJson() methods to convert Java objects to JSON and vice-versa
• Allow pre-existing unmodifiable objects to be converted to and from JSON
• Extensive support of Java Generics
• Allow custom representations for objects
• Support arbitrarily complex objects (with deep inheritance hierarchies and extensive use of generic types)
