- * Execute a function on each affected node.

- * The callback is passed two parameters. The first is a node object which looks
- * like this:
- *
- *   {
- *     // Type of diff, e.g. CreatedNode, ModifiedNode
- *     diffType: 'CreatedNode'
- *
- *     // Type of node affected, e.g. RippleState, AccountRoot
- *     entryType: 'RippleState',
- *
- *     // Index of the ledger this change occurred in
- *     ledgerIndex: '01AB01AB...',
- *
- *     // Contains all fields with later versions taking precedence
- *     //
- *     // This is a shorthand for doing things like checking which account
- *     // this affected without having to check the diffType.
- *     fields: {...},
- *
- *     // Old fields (before the change)
- *     fieldsPrev: {...},
- *
- *     // New fields (that have been added)
- *     fieldsNew: {...},
- *
- *     // Changed fields
- *     fieldsFinal: {...}
- *   }
- *
- * The second parameter to the callback is the index of the node in the metadata
- * (first entry is index 0).
