TheDefault
annotation is used to specify that all fields or methods should be serialized in a default manner. This basically allows an objects fields or properties to be serialized without the need to annotate them. This has advantages if the format of the serialized object is not important, as it allows the object to be serialized with a minimal use of annotations.@Root @Default(DefaultType.FIELD) public class Example { ... }
Defaults can be applied to either fields or property methods. If this annotation is applied to a class, certain fields or methods can be ignored using theTransient
annotation. If a member is marked as transient then it will not be serialized. The defaults are applied only to those members that are not otherwise annotated with an XML annotation.- Author:
