Class EDRFieldMap

java.lang.Object

com.portal.pfc.infranetui.edrviewer.EDRFieldMap

public class EDRFieldMap
extends Object

A field map is an XML document that maps serialized EDR field ids to EDR field names.

EDRFieldMap parses the provided XML document and allows retrieving EDR field names based on the ID specified in the serialized EDR.

The class also provides a static method that takes a serialized EDR and extracts from it the field map name and poid that's specified in the edr's element.

EDRFieldMap

public EDRFieldMap(String fieldMapString)
            throws IOException,
ParserConfigurationException,
SAXException

Creates a FieldMap object by parsing field map XML document.

Parameters:

fieldMapString - XML document in string format that contains the field mapping for serialized EDRs.

Throws:

IOException

ParserConfigurationException

SAXException

Method Details

getElementName

public String getElementName(String id)

Returns name of the edr field specified by id.

This method is currently fairly inefficient as it walks the tree in order to find each element. We should figure out how to use the more efficient getElementById method in order to access the desired element directly.

getFieldMapInfo

public static Pair getFieldMapInfo(String edr)
                            throws SAXException,
IOException

Returns field map's name and poid as specified in the edr. This method uses the SAX parser to parse just enough of the EDR to get the field map information.

Parameters:

edr - Serialized EDR XML in string format

Throws:

SAXException

IOException
