Detailed Description

template<class _Tp>
struct zypp::debug::TraceCAD< _Tp >

A simple tracer for (copy) Construction, Assignment, and Destruction.

To trace class Foo, derive public from TraceCAD<Foo>. This tracer simply calls traceCAD in each traced method, and traceCAD simply drops a line in the log.

This tracer logs construction, copy construction, assignment, destruction and _PING.

assignment: In case the traced class defines an operator= it must be altered to call TraceCAD::operator=, otherwise it won't be triggered.

_PING: Completely up to you. Call _PING somewhere in the traced class to indicate something. In case you overload traceCAD, do whatever is appropriate on _PING. It's just an offer to perform logging or actions here, and not in the traced code.

But traceCAD may be overloaded to produce more stats.
