Path2D.Double,Path2D.Float
public abstract class Path2D extends Object implements Shape, Cloneable
ThePath2Dclass provides a simple, yet flexible shape which represents an arbitrary geometric path. It can fully represent any path which can be iterated by thePathIteratorinterface including all of its segment types and winding rules and it implements all of the basic hit testing methods of theShapeinterface.Use
Path2D.Floatwhen dealing with data that can be represented and used with floating point precision. UsePath2D.Doublefor data that requires the accuracy or range of double precision.Path2Dprovides exactly those facilities required for basic construction and management of a geometric path and implementation of the above interfaces with little added interpretation. If it is useful to manipulate the interiors of closed geometric shapes beyond simple hit testing then theAreaclass provides additional capabilities specifically targeted at closed figures. While both classes nominally implement theShapeinterface, they differ in purpose and together they provide two useful views of a geometric shape wherePath2Ddeals primarily with a trajectory formed by path segments andAreadeals more with interpretation and manipulation of enclosed regions of 2D geometric space.The
PathIteratorinterface has more detailed descriptions of the types of segments that make up a path and the winding rules that control how to determine which regions are inside or outside the path.- Since:

getBounds
public final Rectangle getBounds()
Returns an integerRectanglethat completely encloses theShape. Note that there is no guarantee that the returnedRectangleis the smallest bounding box that encloses theShape, only that theShapelies entirely within the indicatedRectangle. The returnedRectanglemight also fail to completely enclose theShapeif theShapeoverflows the limited range of the integer data type. ThegetBounds2Dmethod generally returns a tighter bounding box due to its greater flexibility in representation.Note that the definition of insideness can lead to situations where points on the defining outline of the
shapemay not be considered contained in the returnedboundsobject, but only in cases where those points are also not considered contained in the originalshape.If a
pointis inside theshapeaccording to thecontains(point)method, then it must be inside the returnedRectanglebounds object according to thecontains(point)method of thebounds. Specifically:shape.contains(x,y)requiresbounds.contains(x,y)If a
pointis not inside theshape, then it might still be contained in theboundsobject:bounds.contains(x,y)does not implyshape.contains(x,y)- Specified by:

getPathIterator
public final PathIterator getPathIterator(AffineTransform at, double flatness)
Returns an iterator object that iterates along theShapeboundary and provides access to a flattened view of theShapeoutline geometry.Only SEG_MOVETO, SEG_LINETO, and SEG_CLOSE point types are returned by the iterator.
If an optional
AffineTransformis specified, the coordinates returned in the iteration are transformed accordingly.The amount of subdivision of the curved segments is controlled by the
flatnessparameter, which specifies the maximum distance that any point on the unflattened transformed curve can deviate from the returned flattened path segments. Note that a limit on the accuracy of the flattened path might be silently imposed, causing very small flattening parameters to be treated as larger values. This limit, if there is one, is defined by the particular implementation that is used.Each call to this method returns a fresh
PathIteratorobject that traverses theShapeobject geometry independently from any otherPathIteratorobjects in use at the same time.It is recommended, but not guaranteed, that objects implementing the
Shapeinterface isolate iterations that are in process from any changes that might occur to the original object's geometry during such iterations.The iterator for this class is not multi-threaded safe, which means that this
Path2Dclass does not guarantee that modifications to the geometry of thisPath2Dobject do not affect any iterations of that geometry that are already in process.- Specified by:
