Bug 136403 – Introduce CSS_SHAPES_BASIC_TYPE_CASTS, and use it

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Gyuyoung Kim]

toCSSBasicFoo() will help to detect wrong type casting. So this patch generates it, and use it instead of static_cast<const CSSBasicFoo*>().

Did you mean to call this function CSS_BASIC_SHAPES_TYPE_CASTS? Otherwise, what do you mean by "CSS_BASIC_TYPE"? I mean, this cast seems specific to the CSSBascShapes class hierarchy.

This led to compile errors as seen in comment #10. Either the second argument needs to be CSSBasicShape::CSSBasicShapeInsetType or, even better, we should namespace qualify the predicate in the definition of CSS_BASIC_TYPE_CASTS().

Would it make sense it call this macro function CSS_SHAPES_BASIC_TYPE_CASTS()?

err, I meant to write:

Would it make sense to call this macro function CSS_BASIC_SHAPE_TYPE_CASTS()?

(So that the name of the macro corresponds to the name of the class CSSBasicShape).
