Method Summary

Modifier and Type	Method and Description
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
boolean	isNodeAdded() Reports whether the HotPixel caused a node to be added in any target segmentString (including its own).
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.

Constructor Detail

HotPixelSnapAction

public HotPixelSnapAction(HotPixel hotPixel,
                          SegmentString parentEdge,
                          int hotPixelVertexIndex)

Method Detail

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
