Detailed Description

Processor to calculate the position in SSDs.

Member Function Documentation

virtual void PositionProcessor::DeclarePlots ( void  )

virtual

Declares the plots for the processor

Reimplemented from EventProcessor.

ChanEvent* PositionProcessor::FindMatchingEdge ( ChanEvent *  match, std::vector< ChanEvent * >::const_iterator  begin, std::vector< ChanEvent * >::const_iterator  end  ) const

private

Find the matching edge of the SSD

Parameters

[in]	match	: the matching edge
[in]	begin	: an iterator to the beginning of the event
[in]	end	: an iterator to the end of the event

Returns

a pointer to the matching ChanEvent

ChanEvent* PositionProcessor::FindMatchingEdge ( ChanEvent *  match, std::vector< ChanEvent * >::const_reverse_iterator  begin, std::vector< ChanEvent * >::const_reverse_iterator  end  ) const

private

Find the matching edge of the SSD

Parameters

[in]	match	: the matching edge
[in]	begin	: an iterator to the beginning of the event
[in]	end	: an iterator to the end of the event

Returns

a pointer to the matching ChanEvent

virtual bool PositionProcessor::Init ( RawEvent &  rawev )

virtual

Reads in QDC parameters from an input file.

The file format allows comment lines at the beginning Followed by QDC lengths Which QDC to use for position calculation followed by the amount to scale the [0,1] result by to physical units And min and max values of the normalized QDC for each location in form: (location) (min) (max) Note that QDC 0 is considered to be a baseline section of the trace for baseline removal for the other QDCs

Parameters

[in]

rawev

: the raw event to get the data from

Returns

true if everything was successful

Reimplemented from EventProcessor.

virtual bool PositionProcessor::Process ( RawEvent &  event )

virtual

Process the QDC data involved in top/bottom side for a strip.

Note: QDC lengths are HARD-CODED at the moment for the plots and to determine the position

Parameters

[in]

event

: the event to process

Returns

true if the processing was successful

Reimplemented from EventProcessor.
