Detailed Description

Tool using the ONNX Runtime C++ API to retrieve constituents based model for boson jet tagging.

this is inspired from the general athena example here: https://gitlab.cern.ch/atlas/athena/-/blob/21.2/Control/AthenaExamples/AthExOnnxRuntime/AthExOnnxRuntime/CxxApiAlgorithm.h

this is implementation is an extension from the one done in rel.21 https://gitlab.cern.ch/atlas/athena/-/tree/21.2/Reconstruction/Jet/AthOnnxRuntimeBJT as the plan is to move to use the central ONNX interface the tool has been merged with the BJT

monitoring jira ticket: https://its.cern.ch/jira/browse/ATLJETMET-1893

◆ extraDeps_update_handler()

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.

#else
      const SG::DataProxy* proxy = evtStore()->proxy( ptr );

#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.

◆ inputHandles()

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()

◆ 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
