Class Dimension2D
- java.lang.Object
-
- java.awt.geom.Dimension2D
- All Implemented Interfaces:
Cloneable
- Direct Known Subclasses:
Dimension
public abstract class Dimension2D extends Object implements Cloneable
The Dimension2D
class is to encapsulate a width and a height dimension.
This class is only the abstract superclass for all objects that store a 2D dimension. The actual storage representation of the sizes is left to the subclass.
- Since:
- 1.2

Method Detail
getWidth
public abstract double getWidth()
Returns the width of this Dimension
in double precision.
- Returns:
- the width of this
Dimension
. - Since:
- 1.2
getHeight
public abstract double getHeight()
Returns the height of this Dimension
in double precision.
- Returns:
- the height of this
Dimension
. - Since:

setSize
public abstract void setSize(double width, double height)
Sets the size of this Dimension
object to the specified width and height. This method is included for completeness, to parallel the getSize
method of Component
.

object -
height
- the new height for theDimension
object - Since:
- 1.2
setSize
public void setSize(Dimension2D d)
Sets the size of this Dimension2D
object to match the specified size. This method is included for completeness, to parallel the getSize
method of Component
.
- Parameters:
-
d
- the new size for theDimension2D
object - Since:
- 1.2
clone
public Object clone()
Creates a new object of the same class as this object.
- Overrides:
-
clone
in classObject
- Returns:
- a clone of this instance.
- Throws:
-
OutOfMemoryError
- if there is not enough memory. - Since:
- 1.2
