`public`
`constructor Create();` |  | Create a new instance of TFPObjectHashTable
`constructor CreateWith();` |  | Create a new hash table with given size and hash function
`function Iterate(); virtual;` |  | Iterate over the objects in the hash table
`procedure Add(); virtual;` |  | Add a new object to the hash table
`property Items: TObject; default; [rw]` |  | Key-based access to the objects

## Description

TFPStringHashTable is a TFPCustomHashTable descendent which stores object instances together with the keys. In case the data associated with the keys are strings themselves, it's better to use TFPStringHashTable, or for arbitrary pointer data, TFPDataHashTable is more suitable. The objects are exposed with their keys through the Items property.
