Method Details

getName
Each io component must have a name that is used inIOFactory.newIO(String)
. The name must be unique thus it is usefull to use a short description or to the class name (this.getClass().getName()
). -
isHandlerFor
Checks if the io component is capable to perform the operation for objects of this class.A typical implementation looks like:
public boolean isHandlerFor(Class value) { if (DataObject.class.isAssignableFrom(value)) return true; return false; }
- Specified by:
isHandlerFor
in interfaceIO
- Parameters:
value
- The class that has to be checked.- Returns:
- Results
true
if the class can oeprate with the given class.
-
copy
overwritten copy-method from Object; use it to copy a complete operator -
getObject
After parsing the document, this method must be called to get the Object. This method can only be called once, because after calling the internal variables are resetted to reuse the object.- Specified by:
getObject
in classAbstractXMLHandler
-
isHandlerFor
Queries the handler for possible handling of the given (SAX-)parameters- Specified by:
isHandlerFor
in classAbstractXMLHandler
- Returns:
-
startElement
public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException SAXParser standard method
- Specified by:
startElement
in interfaceContentHandler
- Throws:
SAXException
-
endElement
- Specified by:
endElement
in interfaceContentHandler
- Throws:
