Specified by:

getParentLocalName in interface ElementContext

Returns:

the local name of the parent element, or the empty string if this element is the root.

getText

public java.lang.String getText()

Get the text contained in this element. It's only valid to call this from EDDElementHandler.handleEndElement.

Specified by:

getText in interface ElementEndContext

getAttributeValue

public java.lang.String getAttributeValue(java.lang.String attributeName)

Get the value of an attribute for this element. It's only valid to call this from EDDElementHandler.handleStartElement.

Specified by:

getAttributeValue in interface ElementStartContext

Parameters:

attributeName - the local name of an XML attribute, must not be null.

Returns:

the value of the specified attribute, or null if not present.

getAttributeNames

public java.util.Iterator getAttributeNames()

Iterates over the collection of attribute names for the element in context.

Specified by:

getAttributeNames in interface ElementStartContext

Returns:

a java.util.Iterator of all attribute names.

getValue

public java.lang.Object getValue(Key key)

Get a value stored in this context.

Specified by:

getValue in interface ElementContext

Parameters:

key - a key for the stored value

Returns:

the stored value, or null if no such value is stored, or the value is stored as null.

putValue

public void putValue(Key key,
                     java.lang.Object value)

Store a value in this context.

Specified by:

putValue in interface ElementContext

Parameters:

key - a key for the value.

value - the value to store, can be null.

public void removeValue(Key key)

Clear a value from this context. This *only* acts on the current scope level.

Specified by:

removeValue in interface ElementContext

registerChildHandler

public void registerChildHandler(java.lang.String namespaceURI,
                                 java.lang.String localName,

Register a handler that will be used only for immediate children of the current element.

Specified by:

registerChildHandler in interface ElementContext

Parameters:

namespaceURI -

localName -

handler -

registerScopeHandler

public void registerScopeHandler(java.lang.String localElementName,
                                 ElementHandler handler)

Description copied from interface: ElementContext

Register a handler that will bs used within the scope of the current element and all its descendants. You should normally call this from ElementHandler.beginElement(). Handlers registered this way are static. To register a factory that dynamically retrieves handlers, use the registerScopeHandlerFactory() method.

Specified by:

registerScopeHandler in interface ElementContext

Parameters:

localElementName - the name of the element to handle

handler - the handler to use

registerScopeHandler

public void registerScopeHandler(java.lang.String namespaceURI,
                                 java.lang.String localElementName,
                                 ElementHandler handler)

Description copied from interface: ElementContext

Register a handler that will bs used within the scope of the current element and all its descendants. You should normally call this from ElementHandler.beginElement(). Handlers registered this way are static. To register a factory that dynamically retrieves handlers, use the registerScopeHandlerFactory() method.

Specified by:

registerScopeHandler in interface ElementContext

Parameters:

namespaceURI - the namespace URI of the element to handle

localElementName - the name of the element to handle

handler - the handler to use

registerScopeHandlerFactory

public void registerScopeHandlerFactory(ElementHandlerFactory factory)

Description copied from interface: ElementContext

Register a factory that can dynamically retrieve element handlers for XML elements in the current scope.

Specified by:

registerScopeHandlerFactory in interface ElementContext

Parameters:

factory - the factory to register

getScopedHandler

public ElementHandler getScopedHandler()

Get a scoped handler for the current element (if any)

getLocator

public XMLLocator getLocator()

Get the locator for the EDD being parsed.

Specified by:

getLocator in interface ElementContext

Returns:

the locator for the EDD being parsed

getMessageReporter

public MessageReporter getMessageReporter()

Description copied from interface: ElementContext

Get the message reporter. Normally you only use this for reporting warnings; any thrown HandlerExceptions will be reported automatically.

Specified by:

getMessageReporter in interface ElementContext

Returns:

the parse message reporter.

setMessageReporter

public void setMessageReporter(MessageReporter reporter)

Specified by:
