Gson invokes this call-back method during deserialization when it encounters a field of the specified type.

In the implementation of this call-back method, you should consider invoking JsonDeserializationContext.deserialize(JsonElement, Type) method to create objects for any non-trivial field of the returned object. However, you should never invoke it on the the same type passing json since that will cause an infinite loop (Gson will call your call-back method again).

Specified by:

deserialize in interface com.google.gson.JsonDeserializer<List<JobExecutionPlan>>

Parameters:

json - The Json data being deserialized

typeOfT - The type of the Object to deserialize to

context -

Returns:

a deserialized object of the specified type typeOfT which is a subclass of T

Throws:

com.google.gson.JsonParseException - if json is not in the expected format of typeofT
