◆ getKey()

SG::sgkey_t asg::AsgTool::getKey ( const void * ptr ) const

inherited

Get the (hashed) key of an object that is in the event store.

This is a bit of a special one. StoreGateSvc and xAOD::TEvent both provide ways for getting the SG::sgkey_t key for an object that is in the store, based on a bare pointer. But they provide different interfaces for doing so.

In order to allow tools to efficiently perform this operation, they can use this helper function.

See also: asg::AsgTool::getName

Parameters

ptr	The bare pointer to the object that the event store should know about

Returns: The hashed key of the object in the store. If not found, an invalid (zero) key.

Definition at line 119 of file AsgTool.cxx.

                                                    {
 
#ifdef XAOD_STANDALONE
      // In case we use @c xAOD::TEvent, we have a direct function call
      // for this.
      return evtStore()->event()->getKey( ptr );
#else
      const SG::DataProxy* proxy = evtStore()->proxy( ptr );
      return ( proxy == nullptr ? 0 : proxy->sgkey() );
#endif // XAOD_STANDALONE
   }

◆ getName()

const std::string & asg::AsgTool::getName ( const void * ptr ) const

inherited

Get the name of an object that is / should be in the event store.

This is a bit of a special one. StoreGateSvc and xAOD::TEvent both provide ways for getting the std::string name for an object that is in the store, based on a bare pointer. But they provide different interfaces for doing so.

In order to allow tools to efficiently perform this operation, they can use this helper function.

See also: asg::AsgTool::getKey

Parameters

ptr	The bare pointer to the object that the event store should know about

Returns: The string name of the object in the store. If not found, an empty string.

Definition at line 106 of file AsgTool.cxx.

                                                            {

#endif // XAOD_STANDALONE
   }

◆ getProperty()

template<class T>

const T * asg::AsgTool::getProperty ( const std::string & name ) const

inherited

Get one of the tool's properties.

◆ initialize()

StatusCode JetDRTrackAssocTool::initialize ( void )

overridevirtual

Dummy implementation of the initialisation function.

It's here to allow the dual-use tools to skip defining an initialisation function. Since many are doing so...

Reimplemented from asg::AsgTool.

◆ inputHandles()

virtual std::vector< Gaudi::DataHandle * > AthCommonDataStore< AthCommonMsg< AlgTool > >::inputHandles ( ) const

overridevirtualinherited

Return this algorithm's input handles.

We override this to include handle instances from key arrays if they have not yet been declared. See comments on updateVHKA.

◆ modify()

virtual StatusCode IJetDecorator::modify ( xAOD::JetContainer & jets ) const

inlinefinaloverridevirtualinherited

Concrete implementation of the function inherited from IJetModifier.

Implements IJetModifier.

Definition at line 32 of file IJetDecorator.h.

32{return decorate(jets);};

IJetDecorator::decorate

virtual StatusCode decorate(const xAOD::JetContainer &jets) const =0

Decorate a jet collection without otherwise modifying it.

    return this->msgStream();
  }

◆ msg_level_name()

const std::string & asg::AsgTool::msg_level_name ( ) const

inherited

A deprecated function for getting the message level's name.

Instead of using this, weirdly named function, user code should get the string name of the current minimum message level (in case they really need it...), with:

MSG::name( msg().level() )

This function's name doesn't follow the ATLAS coding rules, and as such will be removed in the not too distant future.

Returns: The string name of the current minimum message level that's printed

Definition at line 101 of file AsgTool.cxx.

                                                  {

◆ outputHandles()
