Method Detail

clearLocal

protected void clearLocal()

Description copied from class: MappedHandler

Subclasses may override this method to add code to be invoked when MappedHandler.clear() is called.

Overrides:

clearLocal in class MappedHandler<ISemanticArgType>

startTaggedBlock

public void startTaggedBlock(java.lang.String uri,
                             java.lang.String localName,
                             java.lang.String qName,
                             org.xml.sax.Attributes attrs)
                      throws org.xml.sax.SAXException

Description copied from interface: ITaggedBlockTaskHandler

This method is used to run code when entering a tagged block.

Specified by:

startTaggedBlock in interface ITaggedBlockTaskHandler

Overrides:

startTaggedBlock in class MappedHandler<ISemanticArgType>

Parameters:

uri - the Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed

localName - the local name (without prefix), or the empty string if Namespace processing is not being performed

qName - the qualified name (with prefix), or the empty string if qualified names are not available

attrs - the attributes attached to the element. If there are no attributes, it shall be an empty Attributes object. The value of this object after startElement returns is undefined

Throws:

org.xml.sax.SAXException - any SAX exception, possibly wrapping another exception

doGetElement

public ISemanticArgType doGetElement()

Description copied from class: MappedHandler

If subclasses intend to use the MappedHandler.getElement() method, they should override this method to provide the code that constructs the object corresponding to the tagged block.

Overrides:

doGetElement in class MappedHandler<ISemanticArgType>

Returns:

the object corresponding to the tagged block
