inlineinherited

Declare a new Gaudi property.

Parameters

name	Name of the property.
property	Object holding the property value.
doc	Documentation string for the property.

This is the generic version, for types that do not derive from SG::VarHandleKey. It just forwards to the base class version of declareProperty.

Declare a new Gaudi property.

Parameters

name	Name of the property.
property	Object holding the property value.
doc	Documentation string for the property.

This dispatches to either the generic declareProperty or the one for VarHandle/Key/KeyArray.

◆ extraDeps_update_handler()

void AthCommonDataStore< AthCommonMsg< AlgTool > >::extraDeps_update_handler ( Gaudi::Details::PropertyBase & ExtraDeps )

protectedinherited

Add StoreName to extra input/output deps as needed.

use the logic of the VarHandleKey to parse the DataObjID keys supplied via the ExtraInputs and ExtraOuputs Properties to add the StoreName if it's not explicitly given

◆ 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.

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.

◆ initialize()

StatusCode InDet::InDetTrackTruthOriginTool::initialize ( )

overrideprivatevirtual

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.

◆ 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
