public static class MCIndexPointSnapper.HotPixelSnapAction extends MonotoneChainSelectAction

Constructor Details
- HotPixelSnapAction
  
  public HotPixelSnapAction(HotPixel hotPixel, SegmentString parentEdge, int hotPixelVertexIndex)
Method Details
- isNodeAdded
  
  public boolean isNodeAdded()
  
  Reports whether the HotPixel caused a node to be added in any target segmentString (including its own). If so, the HotPixel must be added as a node as well.
  
  Returns:
  
  true if a node was added in any target segmentString.
- select
  
  public void select(MonotoneChain mc, int startIndex)
  
  Check if a segment of the monotone chain intersects the hot pixel vertex and introduce a snap node if so. Optimized to avoid noding segments which contain the vertex (which otherwise would cause every vertex to be noded).
  
  Overrides:
  
  select in class MonotoneChainSelectAction
  
  Parameters:
  
  mc - the parent chain
  
  startIndex - the index of the start vertex of the segment being processed
- addSnappedNode
  
  public boolean addSnappedNode(HotPixel hotPixel, NodedSegmentString segStr, int segIndex)
  
  Adds a new node (equal to the snap pt) to the specified segment if the segment passes through the hot pixel
  
  Parameters:
  
  segStr -
  
  segIndex -
  
  Returns:
  
  true if a node was added to the segment
