Usage

From Java

    public Observable<List<MessageResponse>> getMessages() {
        return RxRealm.listenList(realm -> realm.where(MessageResponse.class)
                .findAllSorted(MessageResponse.CREATED_AT, Sort.DESCENDING));
    }

    public Single<List<MessageResponse>> loadMessages() {
        return mApi.messages()
                .observeOn(Schedulers.computation())
                .doOnSuccess(this::saveMessages);
    }
    
    private Completable saveMessages(List<MessageResponse> messages) {
        return RxRealm.doTransactional(realm -> {
                realm.where(MessageResponse.class).findAll().deleteAllFromRealm();
                realm.copyToRealmOrUpdate(messages);
            });
    }

From Kotlin

    fun getMessages(): Observable<List<MessageResponse>> {
        return RxRealm.listenList{it.where(MessageResponse::class.java)
                .findAllSorted(MessageResponse.CREATED_AT, Sort.DESCENDING)}
    }

    fun loadMessages(): Single<List<MessageResponse>> {
        return mApi.messages()
                .observeOn(Schedulers.computation())
                .doOnSuccess(this::saveMessages)
    }
    
    private saveMessages(messages: List<MessageResponse>): Completable {
        return RxRealm.doTransactional {
                it.where(MessageResponse::class.java).findAll().deleteAllFromRealm()
                it.copyToRealmOrUpdate(messages)
            }
    }
