int PassCuts(const xAOD::TrackParticle *jet, const xAOD::Vertex *pvx)
StatusCode algInitialize()

Run any initializations commmon to all xAH Algorithms (such as registerInstance). Call this inside histInitialize for best results.

StatusCode algFinalize()

Run any finalizations common to all xAH Algorithms (such as unregisterInstance). Call this inside histFinalize for best results.

StatusCode parseSystValVector()

Parse string of systematic sigma levels in m_systValVectorString into m_systValVector.

input container name

std::string m_outContainerName = ""

output container name

std::string m_inJetContainerName = ""

input jet container name

bool m_decorateSelectedObjects = true

decorate selected objects? defaul passSel

bool m_createSelectedContainer = false

fill using SG::VIEW_ELEMENTS to be light weight

int m_nToProcess = -1

look at n objects

int m_pass_min = -1

minimum number of objects passing cuts

int m_pass_max = -1

maximum number of objects passing cuts

bool m_doTracksInJets = false

do track selection on track within jets

std::string m_name = "UnnamedAlgorithm"

All algorithms initialized should have a unique name, to differentiate them at the TObject level.

Note, GetName() returns a char* while this returns a std::string.

bool m_debug = false

m_debug is being deprecated

bool m_verbose = false

m_verbose is being deprecated

MSG::Level m_msgLevel = MSG::INFO

debug level

std::string m_systName = ""

If running systematics, the name of the systematic

float m_systVal = 0.0

If running systematics, the value to set the systematic to

Note

This will set the systematic to the value \(\pm x\).

std::string m_systValVectorString = ""

If running systematics, you can run multiple points and store them in here. A comma separated list of working points should be given to m_systValVectorString, and then parsed by calling parseSystValVector.

std::vector<float> m_systValVector
std::string m_eventInfoContainerName = "EventInfo"

If the xAOD has a different EventInfo container name, set it here

int m_isMC = -1

This is an override at the algorithm level to force analyzing MC or not.

Value Meaning
-1 Default, use eventInfo object to determine if data or mc
0 Treat the input as data
1 Treat the input as MC

Protected Functions

bool isMC()

Try to determine if we are running over data or MC. The xAH::Algorithm::m_isMC can be used

to fix the return value. Otherwise the EventInfo object is queried.

An exception is thrown if the type cannot be determined.

Return Value Meaning
0 Data
1 MC

void registerInstance()

Register the given instance under the moniker xAH::Algorithm::m_className

This will increase the reference count by 1.

int numInstances()

Return number of instances registered under the moniker xAH::Algorithm::m_className

This will return the reference count.

Warning

If for some reason the instance wasn’t registered, we spit out a warning.

void unregisterInstance()

Unregister the given instance under the moniker xAH::Algorithm::m_className

This will decrease the reference count by 1.

Warning

If for some reason the instance wasn’t registered, we spit out a warning.

template <typename T>
StatusCode checkToolStore(const std::string &tool_name)

Check whether the input CP tool already exists with this name in the asg::ToolStore

Depending on the outcome, the content of the map xAH::Algorithm::m_toolAlreadyUsed wll be set accordingly.

bool isToolAlreadyUsed(const std::string &tool_name)

Check whether the input CP tool has been already used by any xAH::Algorithm in the current job by scanning xAH::Algorithm::m_toolAlreadyUsed.

template <typename T>
void setToolName(asg::AnaToolHandle<T> &handle, std::string name = "") const

Note: This function does nothing in release 21.1! The native private tool mechanism is used instead.

Sets the name of a tool. If no name is needed, the tool will use the name of the algorithm plus a unique identifier (xAH::Algorithm::getAddress()) appended to ensure the tool is unique and effectively private.

The tool will not be guaranteed unique if two tools of the same type are created without a name passed in. But this is, at this point, up to the user and a more complex scenario than what this function tries to simplify on its own.

std::string getAddress() const

Return a std::string representation of this

Protected Attributes

std::string m_className = "Algorithm"

The moniker by which all instances are tracked in xAH::Algorithm::m_instanceRegistry

xAOD::TEvent *m_event = nullptr

The TEvent object

xAOD::TStore *m_store = nullptr

The TStore object
