Class JAXBValueStore

java.lang.Object

org.eclipse.persistence.sdo.helper.jaxb.JAXBValueStore

All Implemented Interfaces:

ValueStore

public class JAXBValueStore
extends Object
implements ValueStore

The JAXBValueStore enables a DataObject to access data from a POJO. The link between an SDO property and a POJO property is through their XML representation. For the POJO property this corresponds to its JAXB mapping.

Method Detail

initialize

public void initialize(DataObject aDataObject)

Initialize the value store with its associated DataObject.

Specified by:

initialize in interface ValueStore

getDeclaredProperty

public Object getDeclaredProperty(int propertyIndex)

Get the value from the wrapped POJO, wrapping in DataObjects as necessary.

Specified by:

getDeclaredProperty in interface ValueStore

setDeclaredProperty

public void setDeclaredProperty(int propertyIndex,
                                Object value)

Set the value on the underlying POJO, unwrapping values as necessary.

Specified by:

setDeclaredProperty in interface ValueStore

isSetDeclaredProperty

public boolean isSetDeclaredProperty(int propertyIndex)
