- * IHXValues implementation that preserves order when iterating.
- * This class wraps HXBuffer, buts maintains a linked-list of the
- * elements that are added to the IHXValues, so we can iterate
- * through in the same order they were added.
- *
- * Implemented using SimpleList, so this class is
- * inefficient for large collections.
- *
- * Only the CString methods are supported in this initial implementation
