Creating DataObjects
Using DataFactory
DataObjects can be created by Type using DataFactory:
Type customerType = TypeHelper.INSTANCE.getType("http://www.example.org/customer-example", "customer-type"); DataObject customerDO = DataFactory.INSTANCE.create(customerType);
Using DataObject
Once you have a DataObject you can use it to create child DataObjects based on its properties:
DataObject contactInfoDO = customerDO.createDataObject("contact-info"); DataObject billingAddressDO = contactInfoDO.createDataObject("billing-address");
Getting/Setting Properties
An SDO path (similar to XPath) can be used with the String based accessors:
DataObject billingAddressDO = customerDO.getDataObject("contact-info/billing-address");
