TStringHashMap

Summary

TStringHashMap is a string-pointer associative array.

Pascal

 public TStringHashMap = class(TObject);

Description

TStringHashMap is a string-pointer associative array. It uses a hash table for its implementation, which has several ramifications for its behaviour:

• Lookup by string takes a constant time, i.e. if the map is big enough it takes just as long to find an item from 10 as from 10 million (ignoring cache and paging effects).
• Items are unordered. An iteration of all the items using the Iterate or IterateMethod methods won't go through all the items in any order that has meaning, i.e. the ordering is essentially random.
