jdk.awt.geom.Arc2D — clojure-interop/java.awt 1.0.5

Arc2D is the abstract superclass for all objects that store a 2D arc defined by a framing rectangle, start angle, angular extent (length of the arc), and a closure type (OPEN, CHORD, or PIE).

The arc is a partial section of a full ellipse which inscribes the framing rectangle of its parent RectangularShape.

The angles are specified relative to the non-square framing rectangle such that 45 degrees always falls on the line from the center of the ellipse to the upper right corner of the framing rectangle. As a result, if the framing rectangle is noticeably longer along one axis than the other, the angles to the start and end of the arc segment will be skewed farther along the longer axis of the frame.

The actual storage representation of the coordinates is left to the subclass.

*-chord clj

Static Constant.

The closure type for an arc closed by drawing a straight line segment from the start of the arc segment to the end of the arc segment.

type: int

*-open clj

Static Constant.

The closure type for an open arc with no path segments connecting the two ends of the arc segment.

type: int

*-pie clj

Static Constant.

The closure type for an arc closed by drawing straight line segments from the start of the arc segment to the center of the full ellipse and from that point to the end of the arc segment.

type: int

contains clj

(contains this r)

(contains this x y)

(contains this x y w h)

Determines whether or not the interior of the arc entirely contains the specified rectangle.

x - The X coordinate of the rectangle's upper-left corner. - double y - The Y coordinate of the rectangle's upper-left corner. - double w - The width of the rectangle. - double h - The height of the rectangle. - double

returns: true if the arc contains the rectangle, false if the arc doesn't contain the rectangle. - boolean

contains-angle clj

(contains-angle this angle)

Determines whether or not the specified angle is within the angular extents of the arc.

angle - The angle to test. - double

returns: true if the arc contains the angle, false if the arc doesn't contain the angle. - boolean

equals clj

(equals this obj)

Determines whether or not the specified Object is equal to this Arc2D. The specified Object is equal to this Arc2D if it is an instance of Arc2D and if its location, size, arc extents and type are the same as this Arc2D.

obj - an Object to be compared with this Arc2D. - java.lang.Object

returns: true if obj is an instance of Arc2D and has the same values; false otherwise. - boolean

get-angle-extent clj

(get-angle-extent this)

Returns the angular extent of the arc.

returns: A double value that represents the angular extent of the arc in degrees. - double

get-angle-start clj

(get-angle-start this)

Returns the starting angle of the arc.

returns: A double value that represents the starting angle of the arc in degrees. - double

get-arc-type clj

(get-arc-type this)

Returns the arc closure type of the arc: OPEN, CHORD, or PIE.

returns: One of the integer constant closure types defined in this class. - int

get-bounds-2-d clj

(get-bounds-2-d this)

Returns the high-precision framing rectangle of the arc. The framing rectangle contains only the part of this Arc2D that is in between the starting and ending angles and contains the pie wedge, if this Arc2D has a PIE closure type.

This method differs from the getBounds in that the getBounds method only returns the bounds of the enclosing ellipse of this Arc2D without considering the starting and ending angles of this Arc2D.

returns: the Rectangle2D that represents the arc's framing rectangle. - java.awt.geom.Rectangle2D

get-end-point clj

(get-end-point this)

Returns the ending point of the arc. This point is the intersection of the ray from the center defined by the starting angle plus the angular extent of the arc and the elliptical boundary of the arc.

returns: A Point2D object representing the x,y coordinates of the ending point of the arc. - java.awt.geom.Point2D

get-path-iterator clj

(get-path-iterator this at)

Returns an iteration object that defines the boundary of the arc. This iterator is multithread safe. Arc2D guarantees that modifications to the geometry of the arc do not affect any iterations of that geometry that are already in process.

at - an optional AffineTransform to be applied to the coordinates as they are returned in the iteration, or null if the untransformed coordinates are desired. - java.awt.geom.AffineTransform

returns: A PathIterator that defines the arc's boundary. - java.awt.geom.PathIterator

get-start-point clj

(get-start-point this)

Returns the starting point of the arc. This point is the intersection of the ray from the center defined by the starting angle and the elliptical boundary of the arc.

returns: A Point2D object representing the x,y coordinates of the starting point of the arc. - java.awt.geom.Point2D

hash-code clj

(hash-code this)

Returns the hashcode for this Arc2D.

returns: the hashcode for this Arc2D. - int

intersects clj

(intersects this x y w h)

Determines whether or not the interior of the arc intersects the interior of the specified rectangle.

x - The X coordinate of the rectangle's upper-left corner. - double y - The Y coordinate of the rectangle's upper-left corner. - double w - The width of the rectangle. - double h - The height of the rectangle. - double

returns: true if the arc intersects the rectangle, false if the arc doesn't intersect the rectangle. - boolean

ang-st - The starting angle of the arc in degrees. - double

set-angles clj

(set-angles this p-1 p-2)

(set-angles this x-1 y-1 x-2 y-2)

Sets the starting angle and angular extent of this arc using two sets of coordinates. The first set of coordinates is used to determine the angle of the starting point relative to the arc's center.

The arc will always be non-empty and extend counterclockwise from the first point around to the second point.
