Specified by:

close in interface AutoCloseable

Overrides:

close in class Curve

getCenter

@NotNull
public Coordinate getCenter()

Returns the center of the elliptical arc.

Returns:

the center of the elliptical arc.

getA

public double getA()

Returns the length of the semi-major axis of the elliptical arc.

If the coordinate reference is a geodetic reference, this is expressed in meters. Otherwise the unit of the reference is used.

Returns:

the length of the semi-major axis of the elliptical arc.

getB

public double getB()

Returns the length of the semi-minor axis of the elliptical arc.

If the coordinate reference is a geodetic reference, this is expressed in meters. Otherwise the unit of the reference is used.

Returns:

the length of the semi-minor axis of the elliptical arc.

getStartAngle

@NotNull
public Angle getStartAngle()

Returns the start angle of the elliptical arc.

Returns:

the start angle of the elliptical arc.

getEndAngle

@NotNull
public Angle getEndAngle()

Returns the end angle of the elliptical arc.

Returns:

the end angle of the elliptical arc.

getRotationAngle

@NotNull
public Angle getRotationAngle()

Returns the rotation angle of the elliptical arc.

This property determines the rotation of the axes of the ellipse in which the arc is defined

Returns:

the rotation angle of the elliptical arc.

getAngleDirection

@NotNull
public Angle.Direction getAngleDirection()

Returns the orientation of the arc.

This property determines in which direction the arc extends form the start to the end angle

Returns:

the orientation of the arc.
