Method Details

length

double length()

Returns the length of the path segment

Returns:: the length of the path segment, a positive number

getStart

Point getStart(Point out)

Gets start point of markup segment.

Parameters:: out - the point to store the result of method's execution
Returns:: the start point of this segment

getEnd

Point getEnd(Point out)

Gets end point of markup segment.

Parameters:: out - the point to store the result of method's execution
Returns:: the start point of this segment

setStart

void setStart(Point startPoint)

Sets start point of this segment.

Parameters:: startPoint - the point to set as start point of this segment

setEnd

void setEnd(Point endPoint)

Sets end point of this segment.

Parameters:: endPoint - the point to set as end point of this segment

getDistanceSq

double getDistanceSq(Point givenPoint)

Calculates and returns the square of distance to the given point.

Parameters:: givenPoint -
Returns:: the square of distance to the given point

getNearestPoint

double getNearestPoint(Point givenPoint,
 Point out)

For horizontal segments, calculates (using the output object) the point in this space markup element nearest to the given (x, y) point. Returns the square of distance to the point (in the XY-projection). All the calculations are performed in the horizontal projection (z-coordinates aren't used, as if all of the z coordinates were zero).

Parameters:: x - x coordinate of the point; y - y coordinate of the point; out - the output point to write result to. Note that output.z is left unchanged.
Returns:: the square of distance to the nearest point in the horizontal (XY) projection

getNearestPointOnRay2D

double getNearestPointOnRay2D(double x1,
 double y1,
 double x2,
 double y2,
 Point out)

Calculates (and sets in the 'out' object) the point where this segment intersects the given ray with the minimum distance from ray beginning (if there are several intersection points like in arc segments). Returns the square of that distance.
Returns +infinity if there is no intersections.

Parameters:: x1 - the X coordinate of the start point of the ray; y1 - the Y coordinate of the start point of the ray; x2 - the X coordinate of some point on the ray; y2 - the Y coordinate of some point on the ray; out - the Point object to write result to
Returns:: the square of the distance from ray beginning to the nearest intersection point or +infinity if there is no intersections

getOffsetOfPoint

double getOffsetOfPoint(double x,
 double y)

Calculates distance by segment to the given point. Point is specified by a pair of coordinates. The given point should by on this segment.

Parameters:: x - the x coordinate of the given point.
In case of GIS environment this is the latitude of the given point, measured in degrees (-90 ... (South) ... 0 ... (North) ... +90); y - the y coordinate of the given point
In case of GIS environment this is the longitude of the given point, measured in degrees (-180 ... (West) ... 0 ... (East) ... +180)
Returns:: the distance by segment to the given point

setStartNextTo

void setStartNextTo(IMarkupSegment previousSegment)

Sets coordinates of the end of the specified segment as start coordinates of this segment.

Parameters:: previousSegment - implementation of IMarkupSegment

addTo

@Deprecated
void addTo(Path2D path)

Deprecated.

Adds this segment to the given path assuming that path is currently positioned on the start point of this segment

Parameters:: path - the path to add this segment to
