示例1: InternalAnimValListWillChangeTo
void
DOMSVGAnimatedNumberList::InternalBaseValListWillChangeTo(const SVGNumberList& aNewValue)
{
// When the number of items in our internal counterpart's baseVal changes,
// we MUST keep our baseVal in sync. If we don't, script will either see a
// list that is too short and be unable to access indexes that should be
// valid, or else, MUCH WORSE, script will see a list that is too long and be
// able to access "items" at indexes that are out of bounds (read/write to
// bad memory)!!
RefPtr<DOMSVGAnimatedNumberList> kungFuDeathGrip;
if (mBaseVal) {
if (aNewValue.Length() < mBaseVal->LengthNoFlush()) {
// InternalListLengthWillChange might clear last reference to |this|.
// Retain a temporary reference to keep from dying before returning.
kungFuDeathGrip = this;
}
mBaseVal->InternalListLengthWillChange(aNewValue.Length());
}
// If our attribute is not animating, then our animVal mirrors our baseVal
// and we must sync its length too. (If our attribute is animating, then the
// SMIL engine takes care of calling InternalAnimValListWillChangeTo() if
// necessary.)
if (!IsAnimating()) {
InternalAnimValListWillChangeTo(aNewValue);
}
}示例2:
void
DOMSVGAnimatedNumberList::InternalAnimValListWillChangeTo(const SVGNumberList& aNewValue)
{
if (mAnimVal) {
mAnimVal->InternalListLengthWillChange(aNewValue.Length());
}
}示例3:
nsresult
SVGNumberList::CopyFrom(const SVGNumberList& rhs)
{
if (!mNumbers.SetCapacity(rhs.Length())) {
// Yes, we do want fallible alloc here
return NS_ERROR_OUT_OF_MEMORY;
}
mNumbers = rhs.mNumbers;
return NS_OK;
}
