| * Payload and response for the SObject tree Composite API. The main interface |
| * for specifying what to include in the sumission to the API endpoint. To build |
| * the tree out use: <blockquote> |
| * |
| * <pre> |
| * {@code |
| * Account account = ... |
| * Contact president = ... |
| * Contact marketing = ... |
| * |
| * Account anotherAccount = ... |
| * Contact sales = ... |
| * Asset someAsset = ... |
| * |
| * SObjectTree request = new SObjectTree(); |
| * request.addObject(account).addChildren(president, marketing); |
| * request.addObject(anotherAccount).addChild(sales).addChild(someAsset); |
| * } |
| * </pre> |
| * |
| * </blockquote> This will generate a tree of SObjects resembling: <blockquote> |
| * |
| * <pre> |
| * . |
| * |-- account |
| * | |-- president |
| * | `-- marketing |
| * `-- anotherAccount |
| * `-- sales |
| * `-- someAsset |
| * </pre> |
| * |
| * </blockquote> By default references that correlate between SObjects in the |
| * tree and returned identifiers and errors are handled automatically, if you |
| * wish to customize the generation of the reference implement |
| * {@link ReferenceGenerator} and supply it as constructor argument to |
| * {@link #SObjectTree(ReferenceGenerator)}. |
| * <p/> |
| * Note that the tree can hold single object type at the root of the tree. |
| * |
| * @see ReferenceGenerator |
| * @see SObjectNode |
| * @see AbstractSObjectBase |
| * @see AbstractDescribedSObjectBase |
