revision
double revision
This represents the revision of the class. A revision is used by the deserialization process to determine how to match the annotated fields and methods to the XML elements and attributes. If the version deserialized is different to the annotated revision then annotated fields and methods are not required and if there are excessive XML nodes they are ignored.- Returns:
- this returns the version of the XML class schema
- Default:
- 1.0
