Hi, I try to do exactly the same as show here:
QUOTE: http://svn.freepascal.org/svn/fpc/trunk/packages/fcl-stl/src/gvector.pp generic TVector<T> = class ... ... type TVectorEnumerator = class private FVector: TVector; FPosition: SizeUInt; FFirstDone: Boolean; function GetCurrent: T; inline; public *constructor Create(AVector: TVector);* function MoveNext: Boolean; inline; property Current: T read GetCurrent; end; ... ... public My code: generic TTreap<TKey, TValue> = class ... ... type TTreapEnumerator = class FStack: TStack; FCurrent: PNode; public *constructor Create(ATreap: TTreap);* destructor Destroy; override; function MoveNext: Boolean; property Current: PNode read FCurrent; end; ... ... private Error message I got is: Error: Generics without specialization cannot be used as a type for a variable Then I found this: http://bugs.freepascal.org/view.php?id=19499&history=1 I wonder if this bug's fix is release or not? How does the TVector class compile with this problem? Thanks! Xiangrong
