@express-document-sdk / ReadOnlyItemList
Class: ReadOnlyItemList<T>
ReadOnlyItemList represents an ordered list of API objects, representing items that are all children of the same parent node. (The reverse is not necessarily true, however: this list might not include all children that exist in the parent node. See allChildren for details).
Items in a bare ReadOnlyItemList cannot be added, removed, or reordered. Subclasses like ItemList may add these capabilities, however.
