oracle.javatools.marshal.AttributeMarker

All Implemented Interfaces:

java.io.Serializable

public final class AttributeMarker

extends java.lang.RuntimeException

The AttributeMarker class can be declared in the throws clause of a getter method to indicate to the marshalling code that a particular persistent property should be persisted in XML as an attribute instead of an element. In order for this to succeed, the type of the property must be directly convertible to and from a String form.

Java's ability to annotate methods with metadata at compile-time is very limited. BeanInfo classes tend to be cumbersome and the information in the BeanInfo class can often be overlooked since the BeanInfo code is usually in a separate file and sometimes even in a separate package. By using a "marker exception" in the throws clause of the getter, the fact that the getter represents an XML attribute is readily apparent, especially once the purpose of AttributeMarker is understood.
