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");
