◆ 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
ptrThe 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.

ServiceHandle< StoreGateSvc > & evtStore()

◆ 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
ptrThe 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.

Get one of the tool's properties.

◆ initialize()

StatusCode BJetCorrectionTool::initialize ( void )

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...

◆ 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.

◆ msg()

MsgStream & AthCommonMsg< AlgTool >::msg ( ) const
inlineinherited

Definition at line 24 of file AthCommonMsg.h.

24 {
25 return this->msgStream();
26 }

◆ 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.

101 {
102
103 return MSG::name( msg().level() );
104 }
MsgStream & msg() const
const std::string & name(Level lvl)
Convenience function for translating message levels to strings.

◆ outputHandles()
