Constructor Detail

LineFacetSequence

public LineFacetSequence(LineString line,
                 int start)

Creates a new sequence for a single point from a LineString.

Parameters:

line - the sequence holding the points in the facet sequence

start - the index of the point

LineFacetSequence

public LineFacetSequence(LineString line,
                 int start,
                 int end)

Creates a new section based on a LineString.

Parameters:

line - the sequence holding the points in the section

start - the index of the start point

end - the index of the end point + 1
