| SAXalizerHelper | | public class SAXalizerHelper extends HandlerBase (Code) | | This useful helper class can be used if the XML
root tag itself is required to be the root of the deserialised
object tree. In this case, we can avoid direct use of the SAXalizer and
the SAX API itself, and merely pass in an InputStream attached to the
XML document. The SAXalizerHelper class parses the stream and
returns the single object corresponding to the XML root node,
at the head of the tree of deserialised Java objects.

| produceSubtree | | public Object produceSubtree(Object rootobj, InputStream stream) throws SAXException(Code) | | This method parses a stream attached to an XML document, and returns
a deserialised object tree corresponding to its root node.
Parameters:
rootobj - The required root object to receive the SAXalized subtree. Thisclass must implement (at least) the SAXalizable interface.
Parameters:
stream - A stream attached to an XML document.This stream WILL be closed by this call.
exception:
SAXException - if the stream could not be parsed as XML. An object representing the XML root node. |
| setDocumentLocator | | public void setDocumentLocator(Locator l)(Code) | | |
| startElement | | public void startElement(String tagname, AttributeList attrlist) throws SAXException(Code) | | Implements the DocumentHandler interface. This method is only implemented to
intercept the very first opening tag for the root object, at which point
handling is forwarded to the internal SAXalizer object.
Parameters:
tagname - The tag name for the element just seen in the SAX stream.
Parameters:
attrlist - The attribute list of the tag just seen in the SAX stream.
exception:
SAXException - If any exception requires to be propagated from thisinterface. |
