/**
|
|
* Helper methods for the type-specific WillChangeXXX methods.
|
|
*
|
|
* This method sends out appropriate pre-change notifications so that selector
|
|
* restyles (e.g. due to changes that cause |elem[attr="val"]| to start/stop
|
|
* matching) work, and it returns an nsAttrValue that _may_ contain the
|
|
* attribute's pre-change value.
|
|
*
|
|
* The nsAttrValue returned by this method depends on whether there are
|
|
* mutation event listeners listening for changes to this element's attributes.
|
|
* If not, then the object returned is empty. If there are, then the
|
|
* nsAttrValue returned contains a serialized copy of the attribute's value
|
|
* prior to the change, and this object should be passed to the corresponding
|
|
* DidChangeXXX method call (assuming a WillChangeXXX call is required for the
|
|
* SVG type - see comment below). This is necessary so that the 'prevValue'
|
|
* property of the mutation event that is dispatched will correctly contain the
|
|
* old value.
|
|
*
|
|
* The reason we need to serialize the old value if there are mutation
|
|
* event listeners is because the underlying nsAttrValue for the attribute
|
|
* points directly to a parsed representation of the attribute (e.g. an
|
|
* SVGAnimatedLengthList*) that is a member of the SVG element. That object
|
|
* will have changed by the time DidChangeXXX has been called, so without the
|
|
* serialization of the old attribute value that we provide, DidChangeXXX
|
|
* would have no way to get the old value to pass to SetAttrAndNotify.
|
|
*
|
|
* We only return the old value when there are mutation event listeners because
|
|
* it's not needed otherwise, and because it's expensive to serialize the old
|
|
* value. This is especially true for list type attributes, which may be built
|
|
* up via the SVG DOM resulting in a large number of Will/DidModifyXXX calls
|
|
* before the script finally finishes setting the attribute.
|
|
*
|
|
* Note that unlike using SetParsedAttr, using Will/DidChangeXXX does NOT check
|
|
* and filter out redundant changes. Before calling WillChangeXXX, the caller
|
|
* should check whether the new and old values are actually the same, and skip
|
|
* calling Will/DidChangeXXX if they are.
|
|
*
|
|
* Also note that not all SVG types use this scheme. For types that can be
|
|
* represented by an nsAttrValue without pointing back to an SVG object (e.g.
|
|
* enums, booleans, integers) we can simply use SetParsedAttr which will do all
|
|
* of the above for us. For such types there is no matching WillChangeXXX
|
|
* method, only DidChangeXXX which calls SetParsedAttr.
