Delivery Payloads

+

The SDK provides the JsonUtils class which can be used to deserialize the delivery payload sent + by a subscription. Using the DeliveryPayload class + it will deserialize it correctly to a MessageDeliveryPayload, + ResourceCreatedDeliveryPayload, + ResourceUpdatedDeliveryPayload, or + ResourceDeletedDeliveryPayload

+ + 
DeliveryPayload delivery = JsonUtils.fromJsonString(stringFromResource("messagedeliverypayload.json"),
+    DeliveryPayload.class);
+assertThat(delivery).isInstanceOf(DeliveryPayload.class);
+assertThat(delivery).isInstanceOf(MessageDeliveryPayload.class);
+
See the test code.
+ +

Message Payloads

+

The MessageDeliveryPayload include a helper method to + cast to the inner message delivery and return the wrapped message.

+ + 
DeliveryPayload delivery = JsonUtils.fromJsonString(stringFromResource("messagedeliverypayload.json"),
+    DeliveryPayload.class);
+
+assertThat(delivery).isInstanceOf(MessageDeliveryPayload.class);
+MessageDeliveryPayload messageDelivery = (MessageDeliveryPayload) delivery;
+
+assertThat(messageDelivery.getMessagePayload()).isInstanceOf(CustomerLastNameSetMessagePayload.class);
+
+assertThat(messageDelivery.getMessagePayload().as(CustomerLastNameSetMessagePayload.class))
+        .isInstanceOf(CustomerLastNameSetMessagePayload.class);
+
+assertThat(messageDelivery.hasCompleteMessage()).isTrue();
+
+assertThatThrownBy(() -> messageDelivery.getMessagePayload().as(CustomerFirstNameSetMessagePayload.class))
+        .isInstanceOf(IllegalArgumentException.class);
+
See the test code.

Change Payloads

+ + 
DeliveryPayload delivery = JsonUtils.fromJsonString(stringFromResource("changedeliverypayload.json"),
+    DeliveryPayload.class);
+
+assertThat(delivery).isInstanceOf(ResourceCreatedDeliveryPayload.class);
