示例1:
nsresult
SVGAnimatedLengthList::SetBaseValueString(const nsAString& aValue)
{
SVGLengthList newBaseValue;
nsresult rv = newBaseValue.SetValueFromString(aValue);
if (NS_FAILED(rv)) {
return rv;
}
DOMSVGAnimatedLengthList *domWrapper =
DOMSVGAnimatedLengthList::GetDOMWrapperIfExists(this);
if (domWrapper) {
// We must send this notification *before* changing mBaseVal! If the length
// of our baseVal is being reduced, our baseVal's DOM wrapper list may have
// to remove DOM items from itself, and any removed DOM items need to copy
// their internal counterpart values *before* we change them.
//
domWrapper->InternalBaseValListWillChangeTo(newBaseValue);
}
// We don't need to call DidChange* here - we're only called by
// nsSVGElement::ParseAttribute under nsGenericElement::SetAttr,
// which takes care of notifying.
rv = mBaseVal.CopyFrom(newBaseValue);
if (NS_FAILED(rv) && domWrapper) {
// Attempting to increase mBaseVal's length failed - reduce domWrapper
// back to the same length:
domWrapper->InternalBaseValListWillChangeTo(mBaseVal);
}
return rv;
