Class SchemaRootBase.ExtensionUnmarshaller

java.lang.Object

org.jibx.schema.codegen.custom.SchemaRootBase.ExtensionUnmarshaller

All Implemented Interfaces:

IUnmarshaller

Direct Known Subclasses:

SchemaRootBase.ClassDecoratorUnmarshaller, SchemaRootBase.NameConverterUnmarshaller

Enclosing class:

SchemaRootBase

public abstract static class SchemaRootBase.ExtensionUnmarshaller
extends Object
implements IUnmarshaller

Unmarshaller for extension elements. This expects to find a 'class' attribute giving the name of the class to be created, along with other attributes used to set properties on an instance of the class. The latter attributes are handled by converting the attribute name into a field (with an 'm_' prefix) or method (with a 'set' prefix) name, then storing the value to that field or method.

Constructor Detail

SchemaRootBase.ExtensionUnmarshaller

public SchemaRootBase.ExtensionUnmarshaller(String name)

Constructor.

Parameters:

name - local name for the element handled

Method Detail

createInstance

protected abstract Object createInstance(String cname,
                    UnmarshallingContext ctx)

Instance creation method. This is called by the unmarshal(Object, IUnmarshallingContext) method to create the actual object instance to be handled. Subclasses must implement this method to create the instance and perform any appropriate initialization.

Parameters:

cname - class name from element (null if not supplied)

ctx - unmarshalling context

Returns:

object instance to be unmarshalled, or null if error

isPresent

public boolean isPresent(IUnmarshallingContext ictx)
                  throws JiBXException

Check for element present.

Specified by:

isPresent in interface IUnmarshaller

Parameters:

ictx -

Returns:

true if present, false if not

Throws:

JiBXException - on error

unmarshal

public Object unmarshal(Object obj,
               IUnmarshallingContext ictx)
                 throws JiBXException

Unmarshal instance of element. This ignores the 'class' attribute, if present, since that's intended for use by the subclass.

Specified by:

unmarshal in interface IUnmarshaller

Parameters:

obj - ignored (new instance always created)

ictx -

Returns:

unmarshalled instance

Throws:

JiBXException - on error
