type

  TFPObjectHashTable = class(TFPCustomHashTable)
  public
    constructor Create;
    constructor CreateWith;
    function Iterate(aMethod: TObjectIteratorMethod) : TObject;
    function Iterate(aMethod: TObjectIteratorCallback) : TObject;

Inheritance¶

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.

Properties¶

Member	Visibility	Description
Items	public	Key-based access to the objects.
OwnsObjects read only	public	Does the hash table own the objects ?
