Detailed Description

Align the two polarfires with drop/keep hints signalling successful merge.

• Only checking for /dropped/ events
• assuming that ticks and spills are already in correct ORDER
• assuming spill numbering is NOT the same between the two DPMs

Member Function Documentation

configure()

void hcal::HcalAlignPolarfires::configure ( framework::config::Parameters &  parameters )

overridevirtual

Callback for the EventProcessor to configure itself from the given set of parameters.

The parameters a processor has access to are the member variables of the python class in the sequence that has className equal to the EventProcessor class name.

For an example, look at MyProcessor.

Parameters

parameters

Parameters for configuration.

Reimplemented from framework::EventProcessor.

  max_tick_diff_ = ps.getParameter<int>("max_tick_diff");
}  // configure

produce()

void hcal::HcalAlignPolarfires::produce ( framework::Event &  event )

overridevirtual

Process the event and put new data products into it.

Parameters

event

The Event to process.

Implements framework::Producer.
