Public Constructors

public ExtensionPoint.ExtensionHandler (ExtensionProfile profile, Class<? extends ExtensionPoint> extendedClass)

Constructs a new Handler instance that process extensions on a class associated with the ExtensionPoint. e

Parameters
profile The extension profile associatd with the Handler.
extendedClass The extended class within the profile for this handler

public ExtensionPoint.ExtensionHandler (ExtensionProfile profile, Class<? extends ExtensionPoint> extendedClass, Attributes attrs)

Constructs a new Handler instance that process extensions on a class associated with the ExtensionPoint, and consumes the attributes.

Parameters
profile The extension profile associatd with the Handler.
extendedClass The extended class within the profile for this handler
attrs XML attributes or null to suppress the use of AttributeHelper

Public Methods

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

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.

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 processAttribute(String, String, 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
IOException

public void processEndElement ()

Called to process this element when the closing tag is encountered. The default implementation refuses to accept text() content, unless the handler is configured to accept unrecognized XML with mixed content.

Throws
ParseException
