public class IlpSAXArrayHandler
extends IlpAbstractChainedSAXHandler

Default SAX handler for arrays.

This class is used to retrieve the values of an array in an XML file or stream. It reads the following format:

 [<value [isNull="true"|"false"] javaClass="Java class name">VVV</value>]*
 

Where isNull is false by defaulr and the javaClass is by default the class of the attribute.

VVV can be anything, as long as it can be converted using the type converter IlpDefaultTypeConverter.

JTGO 3.0

readValue

startElement

public void startElement(String namespaceURI,
                         String localName,
                         String qName,
                         Attributes atts)
                  throws SAXException

Notifies the beginning of an element. By default, this method checks whether there is a null XML attribute and clears the content of the element. If you redefine this method, make sure you always call this implementation.

Specified by:

startElement in interface ContentHandler

Overrides:

startElement in class org.xml.sax.helpers.DefaultHandler

Throws:

SAXException

endElement

public void endElement(String namespaceURI,
                       String localName,
                       String qName)
                throws SAXException

Notifies that the end of an element is reached. When this method is called for the finalTag element, the getAttributeValue method is called, the resultHandler.setAttributeValue method is called, and the parsing continues with the parent contentHandler. If you redefine this method, make sure you always call this implementation.

Specified by:

endElement in interface ContentHandler

Overrides:

endElement in class org.xml.sax.helpers.DefaultHandler

Throws:

SAXException
