Detailed Description

Use Iter instead. This class will soon be removed and RangeIter will be made private.

Constructor & Destructor Documentation

RawIter() [1/2]

SkPath::RawIter::RawIter ( )

inline

Initializes RawIter with an empty SkPath. next() on RawIter returns kDone_Verb. Call setPath to initialize SkPath::Iter at a later time.

Returns

RawIter of empty SkPath

Definition at line 1650 of file SkPath.h.

{}

RawIter() [2/2]

SkPath::RawIter::RawIter ( const SkPath &  path )

inline

Sets RawIter to return elements of verb array, SkPoint array, and conic weight in path.

Parameters

path	SkPath to iterate

Returns

RawIter of path

Definition at line 1657 of file SkPath.h.

                                    {
            setPath(path);
        }

Member Function Documentation

conicWeight()

SkScalar SkPath::RawIter::conicWeight ( ) const

inline

Returns conic weight if next() returned kConic_Verb.

If next() has not been called, or next() did not return kConic_Verb, result is undefined.

Returns

conic weight for conic SkPoint returned by next()

Definition at line 1692 of file SkPath.h.

                                     {
            return fConicWeight;
        }

next()

SkPath::Verb SkPath::RawIter::next

(

SkPoint

pts[4]

)

Returns next SkPath::Verb in verb array, and advances RawIter. When verb array is exhausted, returns kDone_Verb. Zero to four SkPoint are stored in pts, depending on the returned SkPath::Verb.

Parameters

pts	storage for SkPoint data describing returned SkPath::Verb

Returns

next SkPath::Verb from verb array

                                             {
    if (!(fIter != fEnd)) {
        return kDone_Verb;
    }
    auto [verb, iterPts, weights] = *fIter;
    int numPts;
    switch (verb) {
        case SkPathVerb::kMove: numPts = 1; break;
        case SkPathVerb::kLine: numPts = 2; break;
        case SkPathVerb::kQuad: numPts = 3; break;
        case SkPathVerb::kConic:
            numPts = 3;
            fConicWeight = *weights;
            break;
        case SkPathVerb::kCubic: numPts = 4; break;
        case SkPathVerb::kClose: numPts = 0; break;
    }
    memcpy(pts, iterPts, sizeof(SkPoint) * numPts);
    ++fIter;
    return (Verb) verb;
}

peek()

Verb SkPath::RawIter::peek ( ) const

inline

Returns next SkPath::Verb, but does not advance RawIter.

Returns

next SkPath::Verb from verb array

Definition at line 1681 of file SkPath.h.

                          {
            return (fIter != fEnd) ? static_cast<Verb>(std::get<0>(*fIter)) : kDone_Verb;
        }

setPath()

void SkPath::RawIter::setPath

(

const SkPath &

path

)

Sets SkPath::Iter to return elements of verb array, SkPoint array, and conic weight in path.

Parameters

path	SkPath to iterate

Definition at line 1911 of file SkPath.cpp.

                                              {
    SkPathPriv::Iterate iterate(path);
    fIter = iterate.begin();
    fEnd = iterate.end();
}
