Bug 121462 – Introduce CSS_VALUE_TYPE_CASTS macro in order to cast CSSValue type

• Component: CSS
• Status: RESOLVED FIXED

[Gyuyoung Kim]

As r155429 introduced ELEMENT_TYPE_CASTS, CSS_VALUE_TYPE_CASTS can be used by css value type casting. This casting macro will help to detect bad-cast bugs. 

This patch adds the following methods,

 - CSSFooValue* toCSSFooValue(CSSValue*)
 - const CSSFooValue* toCSSFooValue(const CSSValue*)
 - CSSFooValue& toCSSFooValue(CSSValue&)
 - const CSSFooValue& toCSSFooValue(const CSSValue&)

Why do we need both CSS_VALUE_TYPE_CASTS and WEBKIT_CSS_VALUE_TYPE_CASTS?
Can't we just have one:

CSS_VALUE_TYPE_CASTS(CSSPrimitiveValue)
CSS_VALUE_TYPE_CASTS(WebKitCSSTransformValue)

Because, naming style of is*Value() is different from isWebKitCSS*Value()

  bool isFilterImageValue() const { return m_classType == FilterImageClass; }
  bool isWebKitCSSFilterValue() const { return m_classType == WebKitCSSFilterClass; }

  ASSERT_WITH_SECURITY_IMPLICATION(!value || value->is##ValueTypeName()); \
  ASSERT_WITH_SECURITY_IMPLICATION(!value || value->isWebKitCSS##ValueTypeName()); \


I couldn't find a way to support both cases in CSS_VALUE_TYPE_CASTS macro. That's why I added two macros as below,Anyway, I will try to find a way to use one macro further. Any idea ?

I feel this patch is too huge. It looks this patch needs to be separated. Patch will be prepared.

[Alexey Proskuryakov]

Rolled out in <http://trac.webkit.org/changeset/156260>, because this caused a bunch of assertion failures, and Gyuyoung agreed that this was the right course of action.

There is no layout test regression on latest patch. I will prepare following patches after landing this master patch.

Why no versions that take references? Maybe we should have versions that take RefPtr too?

Element.h also has similar inline functions. I think it would be good if we support version both together on new bug. I will file a bug.
