ohair@286 | 215 | * |
ohair@286 | 216 | * <p> |
ohair@286 | 217 | * While the unmarshalling is in progress, the {@link #target} field stores the object being unmarshalled. |
ohair@286 | 218 | * This makes it convenient to keep track of the unmarshalling activity in context of XML infoset, but |
ohair@286 | 219 | * since there's only one {@link State} per element, this mechanism only works when there's one object |
ohair@286 | 220 | * per element, which breaks down when we have {@link JAXBElement}, since the presence of JAXBElement |
ohair@286 | 221 | * requires that we have two objects unmarshalled (a JAXBElement X and a value object Y bound to an XML type.) |
ohair@286 | 222 | * |
ohair@286 | 223 | * <p> |
ohair@286 | 224 | * So to make room for storing both, this {@link #backup} field is used. When we create X instance |
ohair@286 | 225 | * in the above example, we set that to {@code state.prev.target} and displace its old value to |
ohair@286 | 226 | * {@code state.prev.backup} (where Y goes to {@code state.target}.) Upon the completion of the unmarshalling |
ohair@286 | 227 | * of Y, we revert this. |
ohair@286 | 228 | * |
ohair@286 | 229 | * <p> |
ohair@286 | 230 | * While this attributes X incorrectly to its parent element, this preserves the parent/child |
ohair@286 | 231 | * relationship between unmarshalled objects and {@link State} parent/child relationship, and |
ohair@286 | 232 | * it thereby makes {@link Receiver} mechanism simpler. |
ohair@286 | 233 | * |
ohair@286 | 234 | * <p> |
ohair@286 | 235 | * Yes, I know this is a hack, and no, I'm not proud of it. |
