Constructor & Destructor Documentation

SkClipStack::Iter::Iter

(

)

Creates an uninitialized iterator.

Must be reset()

Member Function Documentation

const Element* SkClipStack::Iter::next

(

)

Return the clip element for this iterator.

If next()/prev() returns NULL, then the iterator is done.

const Element* SkClipStack::Iter::skipToTopmost

(

SkRegion::Op

op

)

Moves the iterator to the topmost element with the specified RegionOp and returns that element.

If no clip element with that op is found, the first element is returned.
