Gson ignore unknown enum value

[Sean Nguyen]

Hi,

Is there a way to configure gson to ignore an unknown enum value? For
example

in my client code there is an enum DeviceType has 2 enum value : PC,
MOBILE

But when a server is sent another type for example MAC as another
DeviceType. How can I configure my gson deserilalizer to set the
DeviceType = null instead of throwing an exception?

Thanks,

Sean

Have you considered registering a type adapter for your Enum class that implements the desired behavior?

Sean,

If you can recall this far back, how did you configure Gson such that it threw an exception on an unknown enum value? I have the opposite problem in that unknown enum values are deserialized to nulls and no exception is thrown. Thanks!

I guess, there's no way to do this without some own code, see http://code.google.com/p/google-gson/source/browse/trunk/gson/src/main/java/com/google/gson/internal/bind/TypeAdapters.java?r=1120#727.

However, writing a TypeAdapter or a JsonDeserializer should be trivial enough, see https://sites.google.com/site/gson/gson-user-guide#TOC-Custom-Serialization-and-Deserialization.
