Annotation Interface AlsoLoad

@Retention(RUNTIME) @Target({FIELD,METHOD}) public @interface AlsoLoad

Annotation which helps migrate schemas by loading one of several possible properties in the document into fields or methods. This is typically used when a field is renamed, allowing the field to be populated by both its current name and any prior names.

When placed on a field, the additional names (document field) will be checked when this field is loaded. If the document contains data for more than one of the names, an exception will be thrown.
