Examples of com.google.gson.Gson.fromJson()

com.google.gson.Gson.fromJson()
This method deserializes the specified Json into an object of the specified class. It is not suitable to use if the specified class is a generic type since it will not have the generic type information because of the Type Erasure feature of Java. Therefore, this method should not be used if the desired type is a generic type. Note that this method works fine if the any of the fields of the specified object are generics, just the object itself should not be a generic type. For the cases when the object is of generic type, invoke {@link #fromJson(String,Type)}. If you have the Json in a {@link Reader} instead ofa String, use {@link #fromJson(Reader,Class)} instead. @param < T> the type of the desired object @param json the string from which the object is to be deserialized @param classOfT the class of T @return an object of type T from the string @throws JsonParseException if json is not a valid representation for an object of typeclassOfT
