This section explains where and how you use EclipseLink SDO to customize your application to meet requirements.


Performing Actions on Data Objects at Run Time

Use the following classes to perform actions on your data objects:


For more information, see EclipseLink SDO examples.


Using HelperContext

SDO defines a HelperContext interface. You use it to access related SDO helper classes that let you perform common operations such as reading and writing XML documents, defining SDO types from XML Schema, and so on.

To obtain a default context, call the HelperProvider getDefaultContext method.

You can obtain the local context provided by EclipseLink as follows:

HelperContext helperContext = new SDOHelperContext();

For more information, see the following:


What You May Need to Know About Local and Global HelperContext

Using the EclipseLink SDOHelperContext <ttmakeDefaultContext</tt> method, you can promote your local context to become the global (default) one.

Using DataFactory

You use the DataFactory to create disconnected instances of the DataObject.

You can obtain the DataFactory from the HelperContext, and vice versa.
