Method Detail

processAttribute

public void processAttribute(String namespace,
                    String localName,
                    String value)

Description copied from class: XmlParser.ElementHandler

Called to process an attribute. Designed to be overridden by derived classes.

Overrides:

processAttribute in class XmlParser.ElementHandler

Parameters:

namespace - Attribute namespace URI.

localName - Attribute name.

value - Attribute value.

getChildHandler

public XmlParser.ElementHandler getChildHandler(String namespace,
                                       String localName,
                                       Attributes attrs)
                                         throws ParseException,
                                                IOException

Description copied from class: XmlParser.ElementHandler

Determines a handler for a child element.

The default implementation doesn't recognize anything. The result is a schema error unless the parent handler accepts unrecognized XML. XmlParser. localname/namespace.

Overrides:

getChildHandler in class ExtensionPoint.ExtensionHandler

Parameters:

namespace - Child element namespace URI.

localName - Child element name.

attrs - Child element attributes. These attributes will be communicated to the child element handler through its XmlParser.ElementHandler.processAttribute(java.lang.String, java.lang.String, java.lang.String, java.lang.String) method. They are passed here because sometimes the value of some attribute determines the element's content type, so different element handlers may be needed.

Returns:

Child element handler, or null if the child is unrecognized.

Throws:

ParseException - Invalid child element.

IOException - Internal I/O exception (e.g., thrown by XML blob writer).
