FacetSequence

public FacetSequence(CoordinateSequence pts,
                     int start,
                     int end)

Creates a new section based on a CoordinateSequence.

Parameters:

pts - the sequence holding the points in the section

start - the index of the start point

end - the index of the end point + 1

FacetSequence

public FacetSequence(CoordinateSequence pts,
