Method Summary

Attributes	merge(Attributes attributes) Inform this element that it is being merged with an existing element.
WingMergeableElement	mergeChild(String namespace, String localName, String qName, Attributes attributes) Merge the given SAX startElement event into this element's child.

Method Detail

mergeEqual

boolean mergeEqual(String namespace,
                   String localName,
                   String qName,
                   Attributes attributes)
                   throws SAXException,
                          WingException

Determine if the given SAX startElement event is equivalent to this WingElement.

Parameters:

namespace - The element's name space

localName - The local, unqualified, name for this element

qName - The qualified name for this element

attributes - The element's attributes

Returns:

True if this WingElement is equivalent to the given SAX Event.

Throws:

SAXException

WingException

mergeChild

WingMergeableElement mergeChild(String namespace,
                                String localName,
                                String qName,
                                Attributes attributes)
                                throws SAXException,
                                       WingException

Merge the given SAX startElement event into this element's child. If this SAX event matches a child element of this element then it should be removed from the internal book keep of this element and returned. typically this is accomplished by looping through all children elements and returned the first one that returns true for the mergeEqual method.

Parameters:

namespace - The element's name space

localName - The local, unqualified, name for this element *

qName - The qualified name for this element

attributes - The element's attributes

Returns:

The child element

Throws:

SAXException

WingException

merge

Attributes merge(Attributes attributes)
                 throws SAXException,
                        WingException

Inform this element that it is being merged with an existing element. Practically this means that when this method is being transformed to SAX it should assume that the element's SAX events have already been sent. In this case the element would only need to transform to SAX the children of this element. Furthermore, if the element needs to add any attributes to the SAX startElement event it may modify the attributes object passed to make changes.

Returns:

The attributes for this merged element

Throws:

SAXException

WingException
