|
216 |
* Hack for making JAXBElement unmarshalling work. |
|
217 |
* |
|
218 |
* <p> |
|
219 |
* While the unmarshalling is in progress, the {@link #target} field stores the object being unmarshalled. |
|
220 |
* This makes it convenient to keep track of the unmarshalling activity in context of XML infoset, but |
|
221 |
* since there's only one {@link State} per element, this mechanism only works when there's one object |
|
222 |
* per element, which breaks down when we have {@link JAXBElement}, since the presence of JAXBElement |
|
223 |
* requires that we have two objects unmarshalled (a JAXBElement X and a value object Y bound to an XML type.) |
|
224 |
* |
|
225 |
* <p> |
|
226 |
* So to make room for storing both, this {@link #backup} field is used. When we create X instance |
|
227 |
* in the above example, we set that to {@code state.prev.target} and displace its old value to |
|
228 |
* {@code state.prev.backup} (where Y goes to {@code state.target}.) Upon the completion of the unmarshalling |
|
229 |
* of Y, we revert this. |
|
230 |
* |
|
231 |
* <p> |
|
232 |
* While this attributes X incorrectly to its parent element, this preserves the parent/child |
|
233 |
* relationship between unmarshalled objects and {@link State} parent/child relationship, and |
|
234 |
* it thereby makes {@link Receiver} mechanism simpler. |
|
235 |
* |
|
236 |
* <p> |
|
237 |
* Yes, I know this is a hack, and no, I'm not proud of it. |
