Class 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

      • getWidth

        public abstract double getWidth()
        Returns the width of this Dimension in double precision.
        Returns:
        the width of this Dimension.
        Since:

      • getHeight

        public abstract double getHeight()
        Returns the height of this Dimension in double precision.
        Returns:
        the height of this Dimension.
        Since:
        1.2

      • 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.
        Parameters:
        width - the new width for the Dimension object
        height - the new height for the Dimension 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 the Dimension2D object
        Since:
        1.2

      • clone

        public Object clone()
        Creates a new object of the same class as this object.
        Overrides:
        clone in class Object
        Returns:
        a clone of this instance.
        Throws:
        OutOfMemoryError - if there is not enough memory.
