public class MzDataImpMzArrayBinaryBlock
extends MzDataImpCommonPeakList

This class processes an "mzArrayBinary" 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

MzDataImpMzArrayBinaryBlock

public MzDataImpMzArrayBinaryBlock(SessionControl sc)

Default constructor.

Parameters:

sc -

Method Detail

isDoublePrecision

public boolean isDoublePrecision()

Get the doublePrecision.

Returns:

doublePrecision boolean the doublePrecision

setPrecision

public void setPrecision(boolean doublePrecision)

Set the doublePrecision.

Parameters:

doublePrecision - boolean the doublePrecision to set.

getEndian

public String getEndian()

Get the endian.

Returns:

endian String the endian

setEndian

public void setEndian(String endian)

Set the endian.

Parameters:

endian - String the endian to set.

getDataLength

public int getDataLength()

Get the dataLength.

Returns:

dataLength int the dataLength

setDataLength

public void setDataLength(int dataLength)

Set the dataLength.

Parameters:

dataLength - int the dataLength to set.

getDecodedBase64List

public List<Double> getDecodedBase64List()

Get the decodedBase64List.

Returns:

decodedBase64List List the decodedBase64List

setDecodedBase64List

public void setDecodedBase64List(List<Double> decodedBase64List)

Set the decodedBase64List.

Parameters:

decodedBase64List - List the decodedBase64List to set.

isBigEndian

public boolean isBigEndian()

Get the bigEndian.

Returns:

bigEndian boolean bigEndian based on String endian

processInternalStartElement

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

Processes an Internal StartElement event. The blocks in the if-else section are placed in the order of appearance of the start elements in the mzData XML file. This not essential for the functionality, but makes it easier to see if a specific element is handled or not. Elements that may be daughter elements to different types of parent elements, e.g. and , are placed at a suitable location.

Overrides:

processInternalStartElement in class MzDataImpCommon

Parameters:

parser - XMLStreamReader instance.

Throws:

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

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
