Constructor Details

AbstractNetworkCurve

public AbstractNetworkCurve()

Method Details

containsSq

public boolean containsSq(double px,
 double py,
 double squareDistance)

Test if the shape contains the point with the given coordinates (relative to this shape's container, i.e. in the same system with the coordinates of this shape, x and y), using the given tolerance

Parameters:: px - the x coordinate relative to this shape's container; py - the y coordinate relative to this shape's container; squareDistance - the square of distance tolerance to determine whether the given point lies on the path line or not
Returns:: true if the shape contains the point with the given coordinates

getNearestPointOnRay

public double getNearestPointOnRay(double x1,
 double y1,
 double x2,
 double y2,
 Point out)

Calculates the intersection point between this element and the given ray. If there are several intersections, returns the one nearest to the ray start

Parameters:: x1 - the x coordinate of ray start; y1 - the y coordinate of ray start; x2 - the x coordinate of some ray point; y2 - the y coordinate of some ray point; out - the output: intersection point, should be not null
Returns:: the offset of the nearest point or -1 if there is no intersections with the given ray

isClosed

public boolean isClosed()

Returns true if the end point of the last segment equals the start point of the first segment, false otherwise

Returns:: true if this curve is closed

lineTo

public abstract void lineTo(Point endPoint)

Adds line segment (available for markup elements created with no-argument constructor)

Parameters:: endPoint - the segment end point

startDrawing

public abstract void startDrawing(Point startPoint)

Starts drawing (available for markup elements created with no-argument constructor)

Parameters:: startPoint - starting point

getNearestPoint

public double getNearestPoint(Point givenPoint,
 Point out)

Returns the point on this curve closest to the specified point

Parameters:: givenPoint - specified point; out - output object, may be null
Returns:: closest point on the curve
