Improve JsonDeserializationContext type safety #448

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?

Foo foo = ctx.deserialize(jsonElement, Bar.class);

JsonDeserializationContext have the method
<T> T deserialize(JsonElement json, Type typeOfT)

You may accidentally pass wrong typeOfT argument here and it'll explode at 
runtime (Bar do not extend Foo).

Why not make it type safer and make compiler catch the problem:
<T> T deserialize(JsonElement json, TypeToken<T> typeOfT)
<T> T deserialize(JsonElement json, Class<T> typeOfT)

Acknowledged. Unfortunately it's too late to address this. We're encouraging 
use of our new TypeAdapter APIs which are type safe in this way.
