Instance Method

nodeIndex(for:callback:)nodeIndexForHash:callback:nodeIndexForHash_callback_

Enumerates matching node positions for a geometric hash.

func nodeIndex(
    for hash: GSPathHash,
    callback callbackBlock: @escaping (Int, CGFloat, NSPoint, UnsafeMutablePointer<ObjCBool>) -> Void
)
- (void) nodeIndexForHash:(GSPathHash *) hash
                 callback:(void (^)(NSInteger nodeIdx, CGFloat averageAngle, NSPoint averagePos, BOOL *stop)) callbackBlock;
nodeIndexForHash_callback_(
    hash: GSPathHash,
    nodeIdx: int,
    averageAngle: float,
    averagePos: NSPoint,
    stop: bool,
    callbackBlock
)

Discussion

The callback receives the matching node index, the average angle, and the average position. Set stop to YES in the callback to stop enumeration.
