/** * Class DOMSVGLength * * This class creates the DOM objects that wrap internal SVGLength objects that * are in an SVGLengthList. It is also used to create the objects returned by * SVGSVGElement.createSVGLength(). * * For the DOM wrapper classes for non-list SVGLength, see SVGAnimatedLength.h. * * See the architecture comment in DOMSVGAnimatedLengthList.h. * * This class is strongly intertwined with DOMSVGAnimatedLengthList and * DOMSVGLengthList. We are a friend of DOMSVGLengthList, and are responsible * for nulling out our DOMSVGLengthList's pointer to us when we die, making it * a real weak pointer. * * When objects of this type are in a DOMSVGLengthList they belong to an * attribute. While they belong to an attribute, the objects' values come from * their corresponding internal SVGLength objects in the internal SVGLengthList * objects for the attribute. Getting and setting values of a DOMSVGLength * requires reading and writing to its internal SVGLength. However, if the * DOMSVGLength is detached from its DOMSVGLengthList then it first makes a * copy of its internal SVGLength's value and unit so that it doesn't appear to * "lose" its value from script's perspective on being removed from the list. * This means that these DOM tearoffs have space to store these values, even * though they're not used in the common case. * * Objects of this type are also used to reflect the baseVal and animVal of * a single, non-list SVGLength attribute. Getting and settings values of the * DOMSVGLength in this case requires reading and writing to the corresponding * SVGAnimatedLength object. * * This class also stores its current list index, attribute enum, and whether * it belongs to a baseVal or animVal list. This is so that objects of this * type can find their corresponding internal SVGLength. * * To use these classes for <length> attributes as well as <list-of-length> * attributes, we would need to take a bit from mListIndex and use that to * indicate whether the object belongs to a list or non-list attribute, then * if-else as appropriate. The bug for doing that work is: * https://bugzilla.mozilla.org/show_bug.cgi?id=571734
