class XML_API MutationEvent: public Event
The MutationEvent interface provides specific contextual
information associated with Mutation events.
{
public:
enum AttrChangeType
{
MODIFICATION = 1,
The Attr was modified in place.
ADDITION = 2,
The Attr was just added.
REMOVAL = 3
The Attr was just removed.
};
Node* relatedNode() const;
relatedNode is used to identify a secondary node related to a mutation
event. For example, if a mutation event is dispatched
to a node indicating that its parent has changed, the relatedNode is the
changed parent. If an event is instead dispatched to a
subtree indicating a node was changed within it, the relatedNode is
the changed node. In the case of the DOMAttrModified
event it indicates the Attr node which was modified, added, or removed.
const XMLString& prevValue() const;
prevValue indicates the previous value of the Attr node in DOMAttrModified
events, and of the CharacterData node in DOMCharDataModified events.
const XMLString& newValue() const;
newValue indicates the new value of the Attr node in DOMAttrModified
events, and of the CharacterData node in DOMCharDataModified events.
const XMLString& attrName() const;
attrName indicates the name of the changed Attr node in a DOMAttrModified event.
AttrChangeType attrChange() const;
attrChange indicates the type of change which triggered the
DOMAttrModified event. The values can be MODIFICATION,
ADDITION, or REMOVAL.
void initMutationEvent(const XMLString& type, bool canBubble, bool cancelable, Node* relatedNode,
const XMLString& prevValue, const XMLString& newValue, const XMLString& attrName, AttrChangeType change);
The initMutationEvent method is used to initialize the value of a
MutationEvent created through the DocumentEvent
interface. This method may only be called before the MutationEvent
has been dispatched via the dispatchEvent method,
though it may be called multiple times during that phase if
necessary. If called multiple times, the final invocation takes
precedence.
