Function Documentation

chase_hrefs()

static SPGradient * chase_hrefs ( SPGradient *const  src, bool(*)(SPGradient const *)  match  )

static

Returns the first of {src, src->ref->getObject(), src->ref->getObject()->ref->getObject(),...} for which match is true, or NULL if none found.

The raison d'être of this routine is that it correctly handles cycles in the href chain (e.g., if a gradient gives itself as its href, or if each of two gradients gives the other as its href).
