Detailed Description

the interface to histogram storage on the worker

This interface summarizes the subset of Worker that is needed for generating outputs.

Definition at line 29 of file IHistogramWorker.h.

Constructor & Destructor Documentation

◆ ~IHistogramWorker()

virtual EL::IHistogramWorker::~IHistogramWorker ( )

virtualdefaultnoexcept

standard (virtual) destructor

Guarantee: no-fail

Member Function Documentation

◆ addOutput()

virtual void EL::IHistogramWorker::addOutput ( TObject * output_swallow )

pure virtual

effects: add an object to the output.

the worker takes over ownership of the object, but the caller may maintain a reference to it guarantee: basic, argument is always swallowed failures: out of memory I requires: output_swallow != 0 warning: so far I placed no requirements on the output objects. I may do that at a later stage though, possibly breaking existing code.

Implemented in EL::Worker.

◆ getOutputHist()

virtual TObject* EL::IHistogramWorker::getOutputHist ( const std::string & name ) const

pure virtual

get the output histogram with the given name

This is mostly meant, so that I can emulate the Athena histogram mechanism.

Guarantee: strong

Failures: object not found

Postcondition: result != 0
