Sample code using hypothetical TSortedDiskDictionary class

If you had defined your own TSortedDictionary class, the following example shows how the class might be used. Key-value pairs are added to the sorted disk dictionary and then retrieved to verify that they have been properly stored.

      SortedDictionarySample()
      {
          // Create a new disk dictionary.
          TSortedDiskDictionary* myDictionary = new TSortedDiskDictionary("mynewdict");
          
          // NOTE:
          // TOrderableCollectibleLong is an imaginary class that inherits
          // from MOrderableCollectible.
      
          TOrderableCollectibleLong key1(11);
          TCollectibleLong value1(1001);
      
          TOrderableCollectibleLong key2(5);
          TCollectibleLong value2(999);
          
          TOrderableCollectibleLong key3(75);
          TCollectibleLong value3(102456);
      
          // Add some entries to the disk dictionary
          mySortedDictionary->Add(key1, value1);
          mySortedDictionary->Add(key2, value2);
          mySortedDictionary->Add(key3, value3);
      
          // Delete the instance in memory
          delete mySortedDictionary;
      
          // ...Some time later....
          mySortedDictionary = new TSortedDiskDictionary("mynewdict");
      
          // Checking to see if various keys are in the dictionary.
          Boolean found = mySortedDictionary->Member(TOrderableCollectibleLong(11));
          qprintf("11 was found as a key in the sorted dictionary = %d\n", found);
      
          found = mySortedDictionary->Member(TOrderableCollectibleLong(1001));
          qprintf("1001 was found as a key in the sorted dictionary = %d\n", found);
      
          found = mySortedDictionary->Member(TOrderableCollectibleLong(5));
          qprintf("5 was found as a key in the sorted dictionary = %d\n", found);
      
          found = mySortedDictionary->Member(TCollectibleLong(69));
          qprintf("69 was found as a key in the sorted dictionary = %d\n", found);
          
          // Retrieving a value given a key
          TOrderableCollectibleLong* someLong = (TOrderableCollectibleLong*) 
                  mySortedDictionary->Retrieve(TOrderableCollectibleLong(11));
          qprintf("Value associated with 11 is: %d\n", someLong->GetValue());
          delete someLong;
          
          someLong = (TOrderableCollectibleLong*)
                  mySortedDictionary->Retrieve(TOrderableCollectibleLong(75));
          qprintf("Value associated with 75 is: %d\n", someLong->GetValue());
          
          mySortedDictionary->SetDestroyFileOnDelete(TRUE); 
          delete someLong;
          delete mySortedDictionary;
      }
