+ * of the {@code incomingEventSuffix} parameter to it.
+ * <li>It sets the version of the incoming event to the value of the {@code incomingEventVersion} parameter.
+ * <li>It sets the name space of the incoming event to be the value of the package of the class of the incoming Java
+ * object.
+ * <li>It sets the source of the incoming event to the value of the {@code incomingEventSource} parameter.
+ * <li>It sets the target of the incoming event to the value of the {@code incomingEventTarget} parameter.

+ * <li>incomingEventVersion: The event version to use for incoming Java class instances when they are encapsulated in

+ * <li>incomingEventSource: The event source to use for incoming Java class instances when they are encapsulated in Apex
