This section explains where and how you use EclipseLink SDO to customize your application to meet requirements.
Contents
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 create the local context provided by EclipseLink as follows:
HelperContext helperContext = new SDOHelperContext();
For more information, see the following:
- EclipseLink SDOHelperContext API
- EclipseLink HelperContext examples
What You May Need to Know About Local and Global HelperContext
Using the EclipseLink SDOHelperContext makeDefaultContext 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.
