Detailed Description

Converter for Beamline-, Cavity-, Epics- and EVR Data.

Will convert Beamline data, Cavity data, Epics Data and EVR Data

Note

maybe split this to several converters for the different data types will this work. ie is only the epics map copied or the whole event?

prevent copy construction

Member Function Documentation

void Converter::finalize ( CASSEvent *  evt )

virtual

called at the end of the conversion

Parameters

evt	pointer to the event that needs to be finalized

Reimplemented from cass::ConversionBackend.

Definition at line 719 of file machine_converter.cpp.

cass::ConversionBackend::shared_pointer Converter::instance ( )

static

create singleton if doesnt exist already

Definition at line 39 of file machine_converter.cpp.

void cass::MachineData::Converter::operator() ( const Pds::Xtc *  xtc, cass::CASSEvent *  evt  )

virtual

called for appropriate xtc part.

Parameters

xtc	the xtc that contains evr, epics, beamlinedata info
evt	pointer to the event that we will write the data to.

BldDataEBeamV7 is the same as BldDataEBeamV6. A sign-error error was discovered in the calculation of the photon energy that goes into the ebeam bld. This is fixed on the accelerator side, but we will increment the ebeam bld version number to V7 so the data is clearly marked as changed.

need to lock this operation as it involves the store used by all

get the epics header and the epics id for this epics variable

cntrl is a configuration type and will only be send with a configure transition

create a key for the epics list and index. If this is an additional list, prepend the detInfo to the epics variable name

now we need to create the map which we will fill later with real values if this epics variable is an array we want an entry in the map for each entry in the array

go through all entries of the array create an entry in the map with the the index in brackets and initialize it with 0

otherwise we just add the name to the map and initialze it with 0

time is the actual data, that will be send down the xtc with 1 Hz

now we need to find the variable name in the map, therefore we look up the name in the indexmap

if it is an array go through all entries of the array create an entry in the map with the the index in brackets and initialize it with 0

try to find the the name in the map this returns an iterator to the first entry we found if it was an array we can then use the iterator to the next values

if the name is not in the map, ouput error message

otherwise extract the epicsData and write it into the map

set the variable that the epics store was filled

clear the status bytes of the event code

get the evr data

how many events have happened between the last event and now

go through all events and extract the eventcode from them

check if the array is big enough to hold the recorded eventcode

add variables to store, cassevent and to log

BPM X values (mm)

BPM Y values (mm)

BPM TMIT values (Nel)

Converter& cass::MachineData::Converter::operator= ( const Converter &  )

private

prevent assignment

void Converter::prepare ( cass::CASSEvent *  evt )

virtual

called before the conversion

Parameters

evt	pointer to the event that needs to be finalized

clear the beamline data by setting every value to 0 and reset the filled flag

Note

clearing is needed to be done at this point, because the map will be updated multiple times during the conversion process and therefore clearing it during the conversion will erase variables that have already been set.

copy values in the store to the event

Note

we want to add the addional values that are in the store to the beamline data of the event therefore we should not use the assignment operator here
