Create flag that allows only one-way conversion (serialization or deserialization)

[andreas-aeschlimann]

It would be nice if there was a flag for a property that decides whether it should only be serialized or deserialized.

For example, you could have

    @JsonProperty("a", Number)
    a: number = 0;

    @JsonProperty("a", Number)
    b: number = 0;

Now you want deserialize the JSON property a to both class properties a and b, but when serializing you only want to use the class property a.

As of now, in that case there is a collision and b will override a.
