TIHashTable Class

Warning
Deprecated since Delphi XE4. Please use the RSInterfaceCollections\|TIHashTable class instead.

• Add or delete the interfaces in the table.

• Locate and access interfaces in the table.

Note
For a small numbers of items, this class may be slower than a TList because its retrieval time constant is larger. It also consumes more memory than a TList.

Namespace: InterfaceCollections
