Add support for entity specified with Immutables.org

[pogo19]

Hi!

In my project I've recently changed from POJO to Immutables.org. As far as I got, java-dirty doesn't support it. It would be great to support Immutables.org or custom (de)serialization.

Thanks!

Hi Jan,

Can you give an example of where storing an Immutables.org object fails? I've never used this library.

Thanks!

I have a class annotated for generation by Immutables.org, Event.java

@SuppressWarnings("serial")
@Immutable
@Gson.TypeAdapters
public abstract class Event<K, T> implements Serializable {

    @Parameter
    public abstract String getUuid();

    @Parameter
    public abstract long getTimestamp();

    @Parameter
    public abstract int getSchemaVersion();

    @Parameter
    public abstract EventType getType();

    @Parameter
    public abstract String getOriginator();

    @SuppressWarnings("rawtypes")
    @Parameter
    public abstract Class getPayloadIdClass();

    @Parameter
    @Nullable
    public abstract K getPayloadId();

    @SuppressWarnings("rawtypes")
    @Parameter
    public abstract Class getPayloadClass();

    @Parameter
    @Nullable
    public abstract T getPayload();

}

Immutables.org then as a port of java compilation generates ImmutableEvent.java and it is compiled. This ImmutableEvent is standard class extending Event.

When I use directly Event.class in Store.of(), it doesn't know how to handle abstract class. If I use ImmutableEvent.class than I get this error.

Does java-dirty support custom Java objects serialization? Also my Event object has another object (also Immutable) as an attribute (getPayload()), so that the serialized form size can change depending on type of payload object.
