Detailed Description

Acqiris Converter.

this class takes a xtc of type Id_AcqWaveform or Id_AcqConfig and extracts the acqiris channels for all instruments

User definable Parameters:

Converter/LCLSAcqirisDevices/Detector/{size}
Number of user defined detectors to be pulled out of the xtc

Converter/LCLSPixelDetectors/Detector/%id%/{TypeName}
The type of the detector. Only the following types are supported:

Id_AcqConfig : config for Acqiris device
Id_AcqWaveform : data of the Acqiris device

Converter/LCLSAcqirisDevices/%id%/{DetectorName}
Name of the detector. Default is invalid

Converter/LCLSAcqirisDevices/%id%/{DetectorID}
the id of the detector. Default is 0.

Converter/LCLSAcqirisDevices/%id%/{DeviceName}
Name of the detector device

Converter/LCLSAcqirisDevices/%id%/{DeviceID}
Id of the detector device

Converter/LCLSAcqirisDevices/%id%/{CASSID}
the Id the Acqiris should get in the CASSEvent. One needs this number for further processing. Note that the config and the data part must have the same CASSID.

sets up the pds type ids it is responsible for

skip if the either name has not been set or not correctly set

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

virtual

takes the xtc and copies the data to cassevent

skip if there is no corresponding cass key for that xtc

check whether xtc is a configuration or a event

use the right version to extract the info

get the config

if it is a event then extract all information from the event

extract the datadescriptor (waveform etc) from the xtc

retrieve reference to the right acqiris instrument

write the event id of the data to the instrument

retrieve a reference to the channel container of the instrument

resize the channel vector to how many channels are in the device

copy the channel values from the datadescriptor

get a reference instead of a pointer for easier writing

retrieve a reference to the channel we are working on

extract the infos from the datadesc

get pointer to waveform in the datadescriptor

need to shift the pointer so that it looks at the first real point of the waveform

retrieve a reference to waveform within the cassevent channel

resize cassevent waveform container to the correct size

copy the datapoints of the waveform the byte order has to be swapped for some reason that still has to be determined

iterate to next channel

Reimplemented from cass::ConversionBackend.
