Method Details

reset

public void reset(double x,
 double y,
 double radiusDEG)

Description copied from interface: Circle

Expert: Resets the state of this shape given the arguments. This is a performance feature to avoid excessive Shape object allocation as well as some argument error checking. Mutable shapes is error-prone so use with care.

Specified by:

reset in interface Circle

Overrides:

reset in class CircleImpl

getYAxis

protected double getYAxis()

Description copied from class: CircleImpl

The Y coordinate of where the circle axis intersect.

Overrides:

getYAxis in class CircleImpl

relateRectanglePhase2

protected SpatialRelation relateRectanglePhase2(Rectangle r,
 SpatialRelation bboxSect)

Called after bounding box is intersected.

Overrides:

relateRectanglePhase2 in class CircleImpl

Parameters:

bboxSect - INTERSECTS or CONTAINS from enclosingBox's intersection

Returns:

DISJOINT, CONTAINS, or INTERSECTS (not WITHIN)

toString

public String toString()

Overrides:

toString in class CircleImpl
