GdomeMutationEvent objects are designed to signal notification of any changes
to the structure of a document, including attr and text modifications. It may
be noted that none of the mutation events are designated as cancelable. This
stems from the fact that it is very difficult to make use of existing DOM
interfaces which cause document modifications if any change to the document
might or might not take place due to cancelation of the related event.
Note: To create an instance of the GdomeMutationEvent interface, use the feature
string "MutationEvents" as the value of the input parameter used with the
gdome_doc_createEvent() method of the GdomeDocument interface.
the time (in milliseconds relative to the epoch) at which the
event was created. Due to the fact that some systems may not provide this
information the value of timeStamp may be not available for all events.
When not available, a value of 0 will be returned. Examples of epoch time
are the time of the system start or 0:0:0 UTC 1st January 1970.
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.
The initEvent method is used to initialize the value of an Event created
through the gdome_doc_createEvent() API. This method may only be called
before the Event 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. If called from a
subclass of Event interface only the values specified in the initEvent
method are modified, all other attributes are left unchanged.
self :
Event Object ref
eventTypeArg :
Specifies the event type. This type may be any event type
currently defined in this specification or a new event type.
The string must be an XML name.
Any new event type must not begin with any upper, lower, or
mixed case version of the string "DOM".
This prefix is reserved for future DOM event sets. It is
also strongly recommended that third parties adding their
own events use their own prefix to avoid confusion and
lessen the probability of conflicts with other new events.
canBubbleArg :
Specifies whether or not the event can bubble.
cancelableArg :
Specifies whether or not the event's default action can be
prevented.
If an event is cancelable, the preventDefault method is used to signify
that the event is to be canceled, meaning any default action normally
taken by the implementation as a result of the event will not occur. If,
during any stage of event flow, the preventDefault method is called the
event is canceled. Any default action associated with the event will not
occur. Calling this method for a non-cancelable event has no effect. Once
preventDefault has been called it will remain in effect throughout the
remainder of the event's propagation. This method may be used during any
stage of event flow.
The stopPropagation method is used prevent further propagation of an event
during event flow. If this method is called by any EventListener the event
will cease propagating through the tree. The event will complete dispatch
to all listeners on the current EventTarget before event flow stops. This
method may be used during any stage of event flow.
The initMutationEvent method is used to initialize the value of a
GdomeMutationEvent 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.
