• nodeAtIndex:nodeAtIndex_

  The node at an index.

• indexOfNode:indexOfNode_

  The index of a node, or NSNotFound when the node is not in the path.

• firstOncurveNodeIndexfirstOncurveNodeIndex

• nextOncurveNodeFromIndex:nextOncurveNodeFromIndex_

  The next on-curve node after an index.

• previousOncurveNodeFromIndex:previousOncurveNodeFromIndex_

• 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.

• findMinNodefindMinNode

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

• fixStartNodefixStartNode

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

• makeNodeFirst:makeNodeFirst_
