Method Summary

boolean	contains(GM_Object gmo) The Boolean valued operation "contains" shall return TRUE if this GM_Object contains another GM_Object.
CS_CoordinateSystem	getCoordinateSystem() returns the coordinate system of the curve segment
int	getNumberOfPoints() returns the number of points building the curve segment
GM_Position	getPositionAt(int index) returns the curve position at the submitted index
GM_Position[]	getPositions() returns all positions of the segement as array of GM_Point
boolean	intersects(GM_Object gmo) The Boolean valued operation "intersects" shall return TRUE if this GM_Object intersects another GM_Object.
void	reverse() reverses the direction of the curvesegment

Method Detail

getNumberOfPoints

public int getNumberOfPoints()

returns the number of points building the curve segment

getPositions

public GM_Position[] getPositions()

returns all positions of the segement as array of GM_Point

getPositionAt

public GM_Position getPositionAt(int index)

returns the curve position at the submitted index

reverse

public void reverse()

reverses the direction of the curvesegment

getCoordinateSystem

public CS_CoordinateSystem getCoordinateSystem()

returns the coordinate system of the curve segment

intersects

public boolean intersects(GM_Object gmo)

The Boolean valued operation "intersects" shall return TRUE if this GM_Object intersects another GM_Object. Within a GM_Complex, the GM_Primitives do not intersect one another. In general, topologically structured data uses shared geometric objects to capture intersection information.

contains

public boolean contains(GM_Object gmo)

The Boolean valued operation "contains" shall return TRUE if this GM_Object contains another GM_Object.
