◆ getAndRecordJets()

StatusCode JetProvider< xAOD::JetAuxContainer >::getAndRecordJets ( SG::WriteHandle< xAOD::JetContainer > & jetHandle ) const

inlinevirtualinherited

Method to allow the client to pass in a WriteHandle for the container and aux container to be recorded, while the client remains free to modify the output but does not need to know the type of the aux container.

Every class derived from IJetProvider needs to implement the record, providing the explicit type – we should give StoreGate maximal information rather than recording AuxContainerBase

The recommended solution is for the concrete tool to inherit from the templated JetProvider class provided below.

Implements IJetProvider.

◆ 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.

                                                     {

       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.

Parameters

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

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...

◆ initWithOutput()

virtual StatusCode IJetProvider::initWithOutput ( const SG::WriteHandleKey< xAOD::JetContainer > & )

inlinevirtualinherited

Method to allow the client to pass in a WriteHandle during initialisation, in case this is needed for anything...

The main (only?) use case is for copying jets, and propagating any decorations already on the original to the copy in StoreGate

Quietly return success in the general case – the JetRecAlg will always call this, so as to remain agnostic as to the concrete type.

Reimplemented in JetCopier.

Definition at line 65 of file IJetProvider.h.

65 {return StatusCode::SUCCESS;};

◆ inputHandles()

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

   }

◆ 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
