Node Navigation

• node(at:)nodeAtIndex:nodeAtIndex_

  The node at an index.

• firstOncurveNodeIndex()firstOncurveNodeIndexfirstOncurveNodeIndex

  An index from which every segment can be traversed in node order.

• nextOncurveNode(from:)nextOncurveNodeFromIndex:nextOncurveNodeFromIndex_

  The next on-curve node after an index.

• previousOncurveNode(from:)previousOncurveNodeFromIndex:previousOncurveNodeFromIndex_

  The previous on-curve node before an index.

• startNode

  For open paths, returns the first node of the path, otherwise nil.

• endNode

  For open paths, returns the last node of the path, otherwise nil.

• findStartNode()findStartNodefindStartNode

  The node used to begin traversing a closed path, or nil for an open path.

• findMinNode()findMinNodefindMinNode

  The lowest on-curve node, preferring the leftmost node at equal height.

• fixStartNode()fixStartNodefixStartNode

  Moves trailing off-curve nodes to the beginning of a closed path.

• makeNodeFirst(_:)makeNodeFirst:makeNodeFirst_

  Makes a node the start node of the path.

• indexOfTTStartNode()indexOfTTStartNodeindexOfTTStartNode
