We have this internal-DOM split because DOM + * classes are relatively heavy-weight objects with non-optimal interfaces for + * internal code, and they're relatively infrequently used. Having separate + * internal and DOM classes does add complexity - especially for lists where + * the internal list and DOM lists (and their items) need to be kept in sync - + * but it keeps the internal classes light and fast, and in 99% of cases + * they're all that's used. DOM wrappers are only instantiated when script + * demands it. + * + * Ownership model: + * + * The diagram below shows the ownership model between the various DOM objects + * in the tree of DOM objects that correspond to an SVG length list attribute. + * The angled brackets ">" and "<" denote a reference from one object to + * another, where the "!" character denotes a strong reference, and the "~" + * character denotes a weak reference. + * + * .----<!----. .----<!----. .----<!----. + * | | | | | | + * element ~> DOMSVGAnimatedLengthList ~> DOMSVGLengthList ~> DOMSVGLength + * + * Rationale: + * + * The following three paragraphs explain the main three requirements that must + * be met by any design. These are followed by an explanation of the rationale + * behind our particular design. + * + * 1: DOMSVGAnimatedLengthList, DOMSVGLengthLists and DOMSVGLength get to their + * internal counterparts via their element, and they use their element to send + * out appropriate notifications when they change. Because of this, having + * their element disappear out from under them would be very bad. To keep their + * element alive at least as long as themselves, each of these classes must + * contain a _strong_ reference (directly or indirectly) to their element. + * + * 2: Another central requirement of any design is the SVG specification's + * requirement that script must always be given the exact same objects each + * time it accesses a given object in a DOM object tree corresponding to an SVG + * length list attribute. In practice "always" actually means "whenever script + * has kept a references to a DOM object it previously accessed", since a + * script will only be able to detect any difference in object identity if it + * has a previous reference to compare against. + * + * 3: The wiggle room in the "same object" requirement leads us to a third + * (self imposed) requirement: if script no longer has a reference to a given + * DOM object from an object tree corresponding to an SVG length list + * attribute, and if that object doesn't currently have any descendants, then + * that object should be released to free up memory. + * + * To help in understanding our current design, consider this BROKEN design: + * + * .-------------------------------<!-------------------------. + * |--------------------<!----------------. | + * |----<!----. | | + * | | | | + * element ~> DOMSVGAnimatedLengthList !> DOMSVGLengthList !> DOMSVGLength + * + * Having all the objects keep a reference directly to their element like this + * would reduce the number of dereferences that they need to make to get their + * internal counterpart. However, this design does not meet the "same object" + * requirement of the SVG specification. If script keeps a reference to a + * DOMSVGLength or DOMSVGLengthList object, but not to that object's + * DOMSVGAnimatedLengthList, then the DOMSVGAnimatedLengthList may be garbage + * collected. We'd then have no way to return the same DOMSVGLength / + * DOMSVGLengthList object that the script has a reference to if the script + * went looking for it via the DOMSVGAnimatedLengthList property on the + * element - we'd end up creating a fresh DOMSVGAnimatedLengthList, with no + * knowlegde of the existing DOMSVGLengthList or DOMSVGLength object. + * + * The way we solve this problem is by making sure that parent objects cannot + * die until all their children are dead by having child objects hold a strong + * reference to their parent object. Note that this design means that the child + * objects hold a strong reference to their element too, albeit indirectly via + * the strong reference to their parent object: + * + * .----<!----. .----<!----. .----<!----. + * | | | | | | + * element ~> DOMSVGAnimatedLengthList ~> DOMSVGLengthList ~> DOMSVGLength + * + * One drawback of this design is that objects must look up their parent + * chain to find their element, but that overhead is relatively small. + */ +class DOMSVGAnimatedLengthList final : public nsWrapperCache { + friend class DOMSVGLengthList; + + public: + NS_INLINE_DECL_CYCLE_COLLECTING_NATIVE_REFCOUNTING(DOMSVGAnimatedLengthList) + NS_DECL_CYCLE_COLLECTION_SCRIPT_HOLDER_NATIVE_CLASS(DOMSVGAnimatedLengthList) + + /** + * Factory method to create and return a DOMSVGAnimatedLengthList wrapper + * for a given internal SVGAnimatedLengthList object.

SVGAnimatedLengthList::SMILAnimatedLengthList's + * GetBaseValue() and ValueFromString() methods then override this for the + * SMILValue objects that they create to set this flag to the appropriate + * value for the attribute in question. + * + * The reason that we default to setting the mCanZeroPadList to true is + * because the SMIL engine creates "zero" valued SMILValue objects for + * intermediary calculations, and may pass such a SMILValue (along with a + * SMILValue from an animation element - that is a SMILValue created by + * SVGAnimatedLengthList::SMILAnimatedLengthList's GetBaseValue() or + * ValueFromString() methods) into the Add(), ComputeDistance() or + * Interpolate() methods below. Even in the case of animation of list + * attributes that may *not* be padded with zeros (such as 'x' and 'y' on the + * <text> element), we need to allow zero-padding of these "zero" valued + * SMILValue's lists. One reason for this is illustrated by the following + * example: + * + * <text x="2 4">foo + * <animate by="2 2" .../> + * </text> + * + * In this example there are two SMIL animation layers to be sandwiched: the + * base layer, and the layer created for the <animate> element. The SMIL + * engine calculates the result of each layer *independently*, before + * compositing the results together. Thus for the <animate> sandwich layer + * the SMIL engine interpolates between a "zero" SMILValue that it creates + * (since there is no explicit "from") and the "2 2", before the result of + * that interpolation is added to the "2 4" from the base layer. Clearly for + * the interpolation between the "zero" SMILValue and "2 2" to work, the + * "zero" SMILValue's SVGLengthListAndInfo must be zero paddable - hence + * why this method always sets mCanZeroPadList to true. + * + * (Since the Add(), ComputeDistance() and Interpolate() methods may be + * passed two input SMILValue objects for which CanZeroPadList() returns + * opposite values, these methods must be careful what they set the flag to + * on the SMILValue that they output. If *either* of the input SMILValues + * has an SVGLengthListAndInfo for which CanZeroPadList() returns false, + * then they must set the flag to false on the output SMILValue too.

WARNING! WATCH OUT!! + * + * Consumers that modify objects of this type absolutely MUST keep the DOM + * wrappers for those lists (if any) in sync!! That's why this class is so + * locked down. + * + * The DOM wrapper class for this class is DOMSVGPathSegList. + * + * This class is not called |class SVGPathSegList| for one very good reason; + * this class does not provide a list of "SVGPathSeg" items, it provides an + * array of floats into which path segments are encoded. See the paragraphs + * that follow for why. Note that the Length() method returns the number of + * floats in our array, not the number of encoded segments, and the index + * operator indexes floats in the array, not segments. If this class were + * called SVGPathSegList the names of these methods would be very misleading. + * + * The reason this class is designed in this way is because there are many + * different types of path segment, each taking a different numbers of + * arguments. We want to store the segments in an nsTArray to avoid individual + * allocations for each item, but the different size of segments means we can't + * have one single segment type for the nsTArray (not without using a space + * wasteful union or something similar). Since the internal code does not need + * to index into the list (the DOM wrapper does, but it handles that itself) + * the obvious solution is to have the items in this class take up variable + * width and have the internal code iterate over these lists rather than index + * into them. + * + * Implementing indexing to segments with O(1) performance would require us to + * allocate and maintain a separate segment index table (keeping that table in + * sync when items are inserted or removed from the list). So long as the + * internal code doesn't require indexing to segments, we can avoid that + * overhead and additional complexity. + * + * Segment encoding: the first float in the encoding of a segment contains the + * segment's type.
