Detailed Description

template<class T, class TTT>
struct us::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

T	The type of the tracked object.
TTT	The tracked type traits class deriving from this class.
