TInterfaceListIterator.HasMoreElements Method

 Scroll Prev Top Next More

Returns True if there are more elements to retrieve from the enumeration. While this method returns true, the RSInterfaceCollections.TInterfaceListIterator.NextElement method will not raise an exception.

This method is part of the CommonInterfaces.IInterfaceIterator interface.
 

Namespace: RSInterfaceCollections

Delphi

public 
  function HasMoreElements: Boolean; 
 

Return Value

Type: Boolean

Implements

IInterfaceIterator.HasMoreElements
 

The following code shows how to use the iterator to get all the values in a list object, note that this code assumes that every interface in the list is an IFact interface:

Delphi

var
   Values: IInterfaceIterator;
 begin
   Values := TInterfaceListIterator.Create( InterfaceList );
   while Values.HasMoreElements do
   begin
     Values.NextElement;
     ShowMessage( IntToStr((Values.CurrentElement as IFact).ID) + ' = ' +
                  (Values.CurrentElement as IFact).ToString );
   end;
 end;
