Method Detail

### toIntArray

    public static int[] toIntArray(java.util.List list)

### getChains

    public static java.util.List getChains(Coordinate[] pts)

### getChains

    public static java.util.List getChains(Coordinate[] pts,
                                           java.lang.Object context)

  Return a list of the `MonotoneChain`s for the given list of coordinates.

### getChainStartIndices

    public static int[] getChainStartIndices(Coordinate[] pts)

  Return an array containing lists of start/end indexes of the monotone chains for the given list of coordinates. The last entry in the array points to the end point of the point array, for use as a sentinel.
