Detailed Description

template<class T, class TTT>
struct TrackedTypeTraitsBase< T, TTT >

A base class template for type traits for objects tracked by a ServiceTracker instance.

It provides the TrackedType typedef and two dummy method definitions.

Tracked type traits (TTT) classes must additionally provide the following methods:

  • static bool IsValid(const TrackedType& t) Returns true if t is a valid object, false otherwise.
  • static void Dispose(TrackedType& t) Clears any resources held by the tracked object t.
  • static TrackedType DefaultValue() Returns the default value for newly created tracked objects.
Template Parameters
TThe type of the tracked object.
TTTThe tracked type traits class deriving from this class.
