CRStyleSheet* cr_cascade_get_sheet CRCascade a_this,
enum CRStyleOrigin  a_origin
 

Gets a given origin sheet.

Note that the returned stylesheet is refcounted so if the caller wants to manage it's lifecycle, it must use cr_stylesheet_ref()/cr_stylesheet_unref() instead of the cr_stylesheet_destroy() method.

Parameters:
a_this the current instance of CRCascade.
a_origin the origin of the style sheet as defined in the css2 spec in chapter 6.4.
Returns:
the style sheet, or NULL if it does not exist.

CRCascade* cr_cascade_new CRStyleSheet a_author_sheet,
CRStyleSheet a_user_sheet,
CRStyleSheet a_ua_sheet
 

Constructor of the CRCascade class.

Note that all three parameters of this method are ref counted and their refcount is increased. Their refcount will be decreased at the destruction of the instance of CRCascade. So the caller should not call their destructor. The caller should call their ref/unref method instead if it wants

Parameters:
a_author_sheet the autor origin style sheet
a_user_sheet the user origin style sheet.
a_ua_sheet the user agent origin style sheet.
Returns:
the newly built instance of CRCascade or NULL if an error arose during constrution.
