Constructor & Destructor Documentation

Chrono::Chrono ( IChronoSvc *  svc = 0, const std::string &  tag = "CHRONO::UNNAMED"  )

inline

Constructor from Chrono Service and the tag.

IChronoSvc* svc = ... ;

{ // start the scope
  Chrono chrono ( svc , "some unique tag here" ) ;

  for ( long i = 0 ; i < 10000000 ; ++i )
   {
      .. put some CPU-intensive computations here
   }

} // end of the scope, destroy chrono

Parameters

svc	pointer to Chrono Service
tag	the unique tag

Definition at line 53 of file Chrono.h.

    : m_chrono ( 0 )
  { if ( 0 != svc ) { m_chrono = svc -> chronoStart ( tag ) ; } }

Chrono::Chrono ( const std::string &  tag, IChronoSvc *  svc  )

inline

Constructor from Chrono Service and the tag.

IChronoSvc* svc = ... ;

{ // start the scope
  Chrono chrono ( "some unique tag here" , svc ) ;

  for ( long i = 0 ; i < 10000000 ; ++i )
   {
      .. put some CPU-intensive computations here
   }

} // end of the scope, destroy chrono

Parameters

tag	the unique tag
svc	pointer to Chrono Service

    : m_chrono ( 0 )
  { if ( 0 != svc ) { m_chrono = svc -> chronoStart ( tag ) ; } }

Chrono::Chrono ( ChronoEntity *  c )

inline

Constructor from Chrono Object/Entity.

ChronoEntity* chronometer = ... ;

{ // start the scope
  Chrono chrono ( chronometer ) ;

  for ( long i = 0 ; i < 10000000 ; ++i )
   {
      .. put some CPU-intensive computations here
   }

} // end of the scope, destroy chrono

Parameters

c	the pointer to Chrono Object/Entity
