JAXB2 Copyable Plugin (original) (raw)

Copyable plugin

Copyable plugin generates methods for content copying:

public class PurchaseOrderType implements Cloneable, CopyTo //, ...

// ...   

public Object clone() {
    return copyTo(createNewInstance());
}

public Object copyTo(Object target) {
    final CopyStrategy strategy = JAXBCopyStrategy.INSTANCE;
    return copyTo(null, target, strategy);
}

public Object copyTo(ObjectLocator locator, Object target, CopyStrategy strategy) {
    final Object draftCopy = ((target == null)?createNewInstance():target);
    if (draftCopy instanceof PurchaseOrderType) {
        final PurchaseOrderType copy = ((PurchaseOrderType) draftCopy);
        if (this.shipTo!= null) {
            USAddress sourceShipTo;
            sourceShipTo = this.getShipTo();
            USAddress copyShipTo = ((USAddress) strategy.copy(LocatorUtils.property(locator, "shipTo", sourceShipTo), sourceShipTo));
            copy.setShipTo(copyShipTo);
        } else {
            copy.shipTo = null;
        }
        if (this.billTo!= null) {
            USAddress sourceBillTo;
            sourceBillTo = this.getBillTo();
            USAddress copyBillTo = ((USAddress) strategy.copy(LocatorUtils.property(locator, "billTo", sourceBillTo), sourceBillTo));
            copy.setBillTo(copyBillTo);
        } else {
            copy.billTo = null;
        }
        // ...
    }
    return draftCopy;
}

public Object createNewInstance() {
    return new PurchaseOrderType();
}

// ...

}

Generated methods allow you to specify a custom copy creation strategy (copy strategy).

Activation

Use the -Xcopyable argument to activate the plugin.

Configuration

By default, generated code uses :

• org.jvnet.jaxb2_commons.lang.JAXBCopyStrategy as copy strategy for JAXB 2 (javax namespace).
• org.jvnet.jaxb.lang.JAXBCopyStrategy as copy strategy for JAXB 3+ (jakarta namespace).

You can specify class name of your custom strategy using the -Xcopyable-copyStrategyClass argument:

-Xcopyable-copyStrategyClass=com.acme.foo.CustomCopyStrategy
