Class DAC

java.lang.Object
  peakml.io.dac.DAC

public class DAC
extends java.lang.Object

Implementation of a 1-to-1 mapping of the Waters Datafile Access Component. This is a suite of Visual C++ Active Template Library (ATL) classes, allowing for relative easy access to MassLynx raw data files. This suite defines a number of classes to be used for data retrieval, which have been reproduced in this package (DACCalibrationInfo, DACExperimentInfo, DACExScanStats, DACFunctionInfo, DACHeader, DACProcessInfo, DACScanStats, DACSpectrum).

The setup is always that the open-function must be called, which accepts the filename as a parameter at a minimum (this means the file is opened at each access) and occasionally more. In order to track the ionisation mode and the data format (centroid or profile) the class DACExperimentInfo needs to be used. This class retrieves a free-text experiment information, which is interpreted.

This implementation utilizes the associated DLL with a JNI coupling in 'dac.dll'. This means that the MassLynx raw files are only accessible in the windows environment.

Field Summary

static int	RTCODE_FILE_NOT_CLOSED Could not close the data file correctly after reading it.
static int	RTCODE_FILE_NOT_FOUND Cannot find the data file specified.
static int	RTCODE_INVALID_CHROMATOGRAM_TYPE An unrecognized chromatogram type was specified.
static int	RTCODE_INVALID_PROCESS The specified process does not exist.
static int	RTCODE_MISSING_DATA Part of the RAW file is missing, or the process specified does not exist (could be a process "greyed out" in the history list).
static int	RTCODE_NO_HANDLE A handle cannot not be found for the data specified (check that the scan/process number combination is valid)
static int	RTCODE_NOT_INITIALIZED The header was not open
static int	RTCODE_OUT_OF_MEMORY Memory could not be allocated to the read the required data.
static int	RTCODE_PARAMETER_OUT_OF_RANGE One of the function parameters is out of its permitted range.
static int	RTCODE_SCANNUMBER_NOT_FOUND The requested scannumber cannot be found.
static int	RTCODE_SUCCESS The function was completed successfully
