Detailed Description

---

The default behavior of this tool is to use alpha = 1.0, but multiple values of alpha can be used simultaneously. The property AlphaList should be passed a list of floats. Values of < 0 or > 10 may result in problematic output variable names and all values will be rounded to the nearest 0.1. No suffix will be added to the outputs for alpha = 1.0 and for other values a suffix of _AlphaN will be added where N = int(10*alpha).

The DoDichroic option adds dichroic N-subjettiness ratios described in

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.

Get the name of an object that is / should be in the event store.

Returns

initialize()

StatusCode NSubjettinessTool::initialize ( void )

overridevirtual

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...

Call base class initialize to fix up m_prefix

Add alpha = 1.0 by default

Add alpha = m_Alpha by default to keep backwards compatibility

Give warning about deprecation

Use m_Alpha to not break analysis code

Clean up input list of alpha values

Round to the nearest 0.1

Skip negative values of alpha

Store value. std::map::emplace prevents duplicate entries

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.
