Class XSIElementHandler

Object
  XSIElementHandler

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

AnyAttributeHandler, AttributeGroupHandler, AttributeHandler, ComplexContentHandler, ComplexTypeHandler, ElementGroupingHandler, ExtensionHandler, FacetHandler, FieldHandler, IgnoreHandler, ImportHandler, IncludeHandler, KeyHandler, KeyrefHandler, ListHandler, RedefineHandler, RestrictionHandler, RootHandler, SchemaHandler, SelectorHandler, SimpleContentHandler, SimpleTypeHandler, UnionHandler, UniqueHandler

public abstract class XSIElementHandler
extends Object
implements Serializable

This abstract class is intended to act as both a definition of what a generic handler is, and a default handler.

When extending this class, one should as a minimum replace the start/end Element methods.

XSIElementHandler() Creates a new XSIElementHandler object.

Method Summary

void	characters(String text) In most cases this class should not be called within this framework as we do not intend to parse + store all the information required to recreate the exact Schema document being parsed.
abstract void	endElement(String namespaceURI, String localName) handles SAX end Element events. this is an opportunity to complete some post-processing
boolean	equals(Object obj)
abstract XSIElementHandler	getHandler(String namespaceURI, String localName) This method will be used to create the XSI document.
abstract int	getHandlerType() Returns one of the Specified types ... intended for use by the child packages only
abstract String	getLocalName() Returns the LocalName for this element (ie this declaration in the Schema ... so ComplexType or Sequence ...)
abstract int	hashCode()
static void	setLogLevel(Level l) Sets the logging level for all XSIElementHandlers
abstract void	startElement(String namespaceURI, String localName, Attributes attr) handles SAX start Element events.

Constructor Detail

XSIElementHandler

protected XSIElementHandler()

Creates a new XSIElementHandler object. Intended to limit creation to the sub-packages

Method Detail

getHandlerType

public abstract int getHandlerType()

Returns one of the Specified types ... intended for use by the child packages only

Returns:

int (DEFAULT?)

characters

public void characters(String text)
                throws SAXException

In most cases this class should not be called within this framework as we do not intend to parse + store all the information required to recreate the exact Schema document being parsed. As a result, information such as annotations are ignored. When used, they method may be called multiple times for one element. This means the implementor should keep this in mind when overriding this method.

Parameters:

text -

Throws:

SAXException

SAXNotSupportedException

endElement

public abstract void endElement(String namespaceURI,
                                String localName)
                         throws SAXException

handles SAX end Element events. this is an opportunity to complete some post-processing

Parameters:

namespaceURI -

localName -

Throws:

SAXException

startElement

public abstract void startElement(String namespaceURI,
                                  String localName,
                                  Attributes attr)
                           throws SAXException

handles SAX start Element events. This is an opportunity to complete some pre-processing.

Parameters:

namespaceURI -

localName -

attr -

Throws:

SAXException

getHandler

public abstract XSIElementHandler getHandler(String namespaceURI,
                                             String localName)
                                      throws SAXException

This method will be used to create the XSI document. Validation and in-fix processing is expected to exist within this method, along with data logging for post-processing. This method will directly affect the stack being used to complete the parse.

Parameters:

namespaceURI -

localName -

Returns:

XSIElementHandler, or null

Throws:

SAXException

getLocalName

public abstract String getLocalName()

Returns the LocalName for this element (ie this declaration in the Schema ... so ComplexType or Sequence ...)

Returns:

String (not-null)

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

See Also:

Object.equals(java.lang.Object)

hashCode

public abstract int hashCode()

Overrides:

hashCode in class Object

See Also:

Object.hashCode()

setLogLevel

public static void setLogLevel(Level l)

Sets the logging level for all XSIElementHandlers

Parameters:

l -
