MutationEvent

# GdomeSmartDOM::MutationEvent

The MutationEvent interface provides specific contextual information associated with Mutation events.

Inherits from
Event

Default Constructor
MutationEvent(GdomeMutationEvent* = 0)
Creates a smart pointer for the Gdome element whose pointer is passed as an argument. The user should never pass a non-null pointer to this constructor.

Copy and Cast Constructors
MutationEvent(const MutationEvent&) MutationEvent(const Event&)
These constructors can be used to copy a smart pointer or to downcast it. If the downcasting is not possible, the resulting smart pointer will be null.

Copy Operator
MutationEvent& operator=(const MutationEvent&)

Equality
bool operator==(const MutationEvent&) const bool operator!=(const MutationEvent&) const
Two smart pointers are equal if they point to the same Gdome object.

Constants
MODIFICATION = 1 ADDITION = 2 REMOVAL = 3

Attributes
Node get_relatedNode(void) 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.
DOMString get_prevValue(void) const
prevValue indicates the previous value of the Attr node in DOMAttrModified events, and of the CharacterData node in DOMCharDataModified events.
DOMString get_newValue(void) const
newValue indicates the new value of the Attr node in DOMAttrModified events, and of the CharacterData node in DOMCharDataModified events.
DOMString get_attrName(void) const
attrName indicates the name of the changed Attr node in a DOMAttrModified event.
unsigned short get_attrChange(void) const
attrChange indicates the type of change which triggered the DOMAttrModified event. The values can be MODIFICATION, ADDITION, or REMOVAL.

Methods
void initMutationEvent(const DOMString& typeArg, const boolcanBubbleArg, const boolcancelableArg, const Node& relatedNodeArg, const DOMString& prevValueArg, const DOMString& newValueArg, const DOMString& attrNameArg, const unsigned shortattrChangeArg) const
Parameters: typeArg Specifies the event type. canBubbleArg Specifies whether or not the event can bubble. cancelableArg Specifies whether or not the event's default action can be prevented. relatedNodeArg Specifies the Event's related Node prevValueArg Specifies the Event's prevValue attribute newValueArg Specifies the Event's newValue attribute attrNameArg Specifies the Event's attrName attribute attrChangeArg Specifies the Event's attrName attribute Description: 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.
