[explicit] AbstractOperationTracer::AbstractOperationTracer(QInstaller::Operation *operation)
Constructs tracer for operation. Objects of this class cannot be constructed directly, but the derived classes should explicitly call the base class constructor in their constructors.
[virtual constexpr noexcept] AbstractOperationTracer::~AbstractOperationTracer()
Destructs object. A subclass may override this method.
[pure virtual] void AbstractOperationTracer::trace(const QString &state)
Prints trace output for starting operation in state. A subclass should implement this method.
