public class MzDataImpDetectorBlock
extends MzDataImpCommonPeakListSet

This class processes a "detector" XML block in an mzData file. An mzData file contains information on a mass spectrometry experiment. The mzData file is first vaildated against the XML Schema Definition file mzdata.xsd. If the file is valid, its content is parsed and selected information stored in Proteios. The mzData file is parsed using cursor-based XML stream parsing. The StAX (Stream API for XML) parser finds start and stop (end) tags, which are then processed. Element attributes are located in the start tag, and elements of simple types are stored directly after the start tag is read. For more complex elements, values of attributes and sub-elements are collected in temporary variables, until the end tag is reached, and the colelcted contents are stored. Example: XML tag tagData At start tag: Method thisTagElementStart() stores attribute values. Between tags: tagData is stored in temporary StringBuffer. At end tag: Method thisTagItem() processes collected data. Tag data may be exchanged for a start/end tag pair, etc.

Constructor Detail

MzDataImpDetectorBlock

public MzDataImpDetectorBlock(SessionControl sc)

Default constructor.

Method Detail

blockEnd

public void blockEnd(javax.xml.stream.XMLStreamReader parser)
              throws javax.xml.stream.XMLStreamException

Processes end of XML block processed by this class. Extracts data in block.

Overrides:

blockEnd in class MzDataImpCommon

Parameters:

parser - XMLStreamReader instance.

Throws:

javax.xml.stream.XMLStreamException - If there is an XML Stream related error

processInternalStartElement

public void processInternalStartElement(javax.xml.stream.XMLStreamReader parser)
                                 throws javax.xml.stream.XMLStreamException

Processes an internal StartElement event.

Overrides:

processInternalStartElement in class MzDataImpCommon

Parameters:

parser - XMLStreamReader instance.

Throws:

javax.xml.stream.XMLStreamException - If there is an XML Stream related error

cvParamElementStart

public void cvParamElementStart(javax.xml.stream.XMLStreamReader parser)
                         throws javax.xml.stream.XMLStreamException

Processes start of cvParam XML element. Extracts data from attributes.

Parameters:

parser - XMLStreamReader instance.

Throws:

javax.xml.stream.XMLStreamException - If there is an XML Stream related error

userParamElementStart

public void userParamElementStart(javax.xml.stream.XMLStreamReader parser)
                           throws javax.xml.stream.XMLStreamException

Processes start of userParam XML element. Extracts data from attributes. A userParam tag has the format: where [userParamName} and {userParamValue} are the strings that are extracted.

Parameters:

parser - XMLStreamReader instance.

Throws:

javax.xml.stream.XMLStreamException - If there is an XML Stream related error

detectorItem

public HardwareConfiguration detectorItem(PeakListSet peakListSet,
                                          Hardware instrument)

Creates a detector item.

Parameters:

peakListSet - PeakListSet peakListSet

instrument - Hardware instrument

Returns:

HardwareConfiguration detector

storeDetectorAnnotations

public void storeDetectorAnnotations(HardwareConfiguration detector)

Stores variable values as annotations for detector.

Parameters:

detector - HardwareConfiguration detector
