Detailed Description

Create / access multi purpose counters.

Counter Creation: ----------------- 

   // counter creation:
   ICounterSvc::CountObject obj = svc->create("AlgName","NumExecuted",0);

    obj++;
    obj += 10;

    ICounterSvc::Counter*  m_counter = obj.counter();
    // ICounterSvc::Counter*  m_counter = obj ; ///< the same

    ICounterSvc::Counter* m_counter = 0;
    if ( svc->create("AlgName","NumExecuted",0, m_counter).isSuccess() )
    {
       CountObject obj(m_counter);
       obj++;
    }

Counter access: ---------------

   ICounterSvc::Counter* m_counter = svc->get("AlgName","NumExecuted");
   if ( m_counter )  {....}

   // or:

   try {
     ICounterSvc::CountObject obj(svc->get("AlgName","NumExecuted"));
     obj++;
   }
   catch(std::invalid_argument e)  {
      ...handle exception ...
   }

typedef Stat ICounterSvc::CountObject

Ease the manipulation of counters in a way, that they behave like objects: Avoid: Counter* cnt = .

..; ++(*cnt);

Instead: Counter* cnt = ...; CountObject obj(cnt); ++cnt;

Note: No inheritance! This class has no virtual destructor

Member Function Documentation

ICounterSvc::DeclareInterfaceID ( ICounterSvc  ,
4  ,
0   
)

InterfaceID.

virtual Counter* ICounterSvc::get ( const std::string &  group,
const std::string &  name 
) const [pure virtual]

Access an existing counter object.

Parameters:
group [IN] Hint for smart printing
name [IN] Counter name
createIf [IN] flag to indicate the creation if not counter found
Returns:
Pointer to existing counter object (NULL if non existing).

Implemented in CounterSvc.

virtual Counters ICounterSvc::get ( const std::string &  group  )  const [pure virtual]

get all counters form the given group: 

    ICounterSvc::Counters cnts = svc->get("Efficiency") ;

    MsgStream& stream = ... ;
    for ( ICounterSvc::Counters::const_iterator ic = cnts.begin()  ;
          cnts.end() != ic ; ++ic )
       {
          stream << (*ic) << endmsg ;
       }
See also:
ICounterSvc::Counters
Parameters:
gorup the gorup name
Returns:
vector of the properly initialized counters

Implemented in CounterSvc.

virtual StatusCode ICounterSvc::create ( const std::string &  group,
const std::string &  name,
longlong  initial_value,
Counter *&  refpCounter 
) [pure virtual]

Create a new counter object.

If the counter object exists already the existing object is returned. In this event the return code is COUNTER_EXISTS. The ownership of the actual counter stays with the service.

Parameters:
group [IN] Hint for smart printing
name [IN] Counter name
initial_value [IN] Initial counter value
refpCounter [OUT] Reference to store pointer to counter.
Returns:
StatusCode indicating failure or success.

Implemented in CounterSvc.

virtual CountObject ICounterSvc::create ( const std::string &  group,
const std::string &  name,
longlong  initial_value = 0 
) [pure virtual]

If the counter object exists already, a std::runtime_error exception is thrown.

The ownership of the actual counter stays with the service.

Parameters:
group [IN] Hint for smart printing
name [IN] Counter name
initial_value [IN] Initial counter value
refpCounter [OUT] Reference to store pointer to counter.
Returns:
Fully initialized CountObject.

Implemented in CounterSvc.

virtual StatusCode ICounterSvc::remove ( const std::string &  group,
const std::string &  name 
) [pure virtual]

Remove a counter object.

If the counter object does not exists, the return code is COUNTER_NOT_PRESENT. The counter may not be used anymore after this call.

Parameters:
group [IN] Hint for smart printing
name [IN] Counter name
initial_value [IN] Initial counter value
refpCounter [OUT] Reference to store pointer to counter.
Returns:
StatusCode indicating failure or success.

Implemented in CounterSvc.

virtual StatusCode ICounterSvc::remove ( const std::string &  group  )  [pure virtual]

Remove all counters of a given group.

If no such counter exists the return code is COUNTER_NOT_PRESENT

Parameters:
group [IN] Hint for smart printing
Returns:
StatusCode indicating failure or success.

Implemented in CounterSvc.

virtual StatusCode ICounterSvc::print ( const std::string &  group,
const std::string &  name,
Printout &  printer 
) const [pure virtual]

Print counter value.

Parameters:
group [IN] Hint for smart printing
name [IN] Counter name
printer [IN] Print actor
Returns:
StatusCode indicating failure or success.

Implemented in CounterSvc.

virtual StatusCode ICounterSvc::print ( const std::string &  group,
Printout &  printer 
) const [pure virtual]

If no such counter exists the return code is COUNTER_NOT_PRESENT Note: This call is not direct access.

Parameters:
group [IN] Hint for smart printing
printer [IN] Print actor
Returns:
StatusCode indicating failure or success.

Implemented in CounterSvc.

virtual StatusCode ICounterSvc::print ( const Counter *  pCounter,
Printout &  printer 
) const [pure virtual]

Print counter value.

Parameters:
pCounter [IN] Pointer to Counter object
printer [IN] Print actor
Returns:
StatusCode indicating failure or success.

Implemented in CounterSvc.

virtual StatusCode ICounterSvc::print ( const CountObject &  pCounter,
Printout &  printer 
) const [pure virtual]

Print counter value.

Parameters:
refCounter [IN] Reference to CountObject object
printer [IN] Print actor
Returns:
StatusCode indicating failure or success.

Implemented in CounterSvc.

virtual StatusCode ICounterSvc::print ( Printout &  printer  )  const [pure virtual]

Parameters:
printer [IN] Print actor
Returns:
StatusCode indicating failure or success.

Implemented in CounterSvc.

virtual StatusCode ICounterSvc::defaultPrintout ( MsgStream &  log,
const Counter *  pCounter 
) const [pure virtual]

Default Printout for counters.

Implemented in CounterSvc.
