OrderedDictionary - An Overview | Embarcadero

An OrderedDictionary is a data structure that maintains the order of keys while allowing key-value pairs to be stored and accessed. Unlike standard dictionaries, which do not guarantee order, an OrderedDictionary preserves the sequence in which items are added. This makes it ideal for scenarios where the order of insertion matters, providing efficient lookups and ordered iteration over elements.
