DefaultArcString

public DefaultArcString(Points controlPoints)

Creates a new DefaultArcString instance from the given parameters.

Parameters:

controlPoints - interpolation points

Method Detail

getCoordinateDimension

public int getCoordinateDimension()

Description copied from interface: CurveSegment

Returns the coordinate dimension, i.e. the dimension of the space that the curve is embedded in.

Specified by:

getCoordinateDimension in interface CurveSegment

Returns:

Returns the number of arcs of the string.

Specified by:

getNumArcs in interface ArcString

Returns:

the number n of arcs (n >= 1)

getStartPoint

public Point getStartPoint()

Description copied from interface: CurveSegment

Returns the start point of the segment.

Specified by:

getStartPoint in interface CurveSegment

Returns:

the start point of the segment

getEndPoint

public Point getEndPoint()

Description copied from interface: CurveSegment

Returns the end point of the segment.

Specified by:

getEndPoint in interface CurveSegment

Returns:

the end point of the segment

getSegmentType

public CurveSegment.CurveSegmentType getSegmentType()

Description copied from interface: CurveSegment

Returns the type of curve segment.

Specified by:

getSegmentType in interface CurveSegment

Returns:

the type of curve segment
