Detailed Description

template<typename T>
class ns3::TracedValue< T >

Trace classes with value semantics.

If you want to trace the change of value of a class or primitive type which have value semantics (they must support operator !=), you can wrap them in an instance of this template. This instance will behave just like the original class (if it did not export any special method), and will define Connect/DisconnectWithoutContext methods to work with MakeTraceSourceAccessor.

Template Parameters

T	[explicit] The type of the underlying value being traced.
