Constructor Detail

GDimension

public GDimension()

Constructs a new dimension object with zero values for width and height.

GDimension

public GDimension(double width,
          double height)

Constructs a new dimension object with the specified components.

Parameters:

width - The width of the dimension object

height - The height of the dimension object

GDimension

public GDimension(GDimension size)

Constructs a new GDimension object from an existing one.

Parameters:

size - An existing GDimension object specifying the size

GDimension

public GDimension(java.awt.Dimension size)

Constructs a new GDimension object from an AWT Dimension.

Parameters:

size - An AWT Dimension object specifying the size

Method Detail

getWidth

public double getWidth()

Returns the width of this GDimension.

Returns:

The width of this GDimension

getHeight

public double getHeight()

Returns the height of this GDimension.

Returns:

The height of this GDimension

setSize

public void setSize(double width,
           double height)

Sets the components of the dimension object from the specified parameters.

Parameters:

width - The new width of the dimension object

height - The new height of the dimension object

setSize

public void setSize(GDimension size)

Sets the width and height of one GDimension object equal to that of another.

Parameters:

size - A GDimension object specifying the new size

getSize

public GDimension getSize()

Returns a new GDimension object equal to this one.

Returns:

A new GDimension object with the same size

toDimension

public java.awt.Dimension toDimension()

Converts this GDimension to the nearest integer-based Dimension.

Returns:

The closest integer-based Dimension object

hashCode

public int hashCode()

Returns an integer hash code for the dimension object. The hash code for a GDimension is constructed from the hash codes from the float values of the width and height, which are the ones used in the equals method.

Overrides:

hashCode in class java.lang.Object

Returns:

The hash code for this dimension object

equals

public boolean equals(java.lang.Object obj)

Tests whether two GDimension objects are equal. Because floating-point values are inexact, this method checks for equality by comparing the float values (rather than the double values) of the coordinates.

Overrides:

equals in class java.lang.Object

Parameters:

obj - Any object

Returns:

true if the obj is a GDimension equal to this one, and false otherwise

toString

public java.lang.String toString()

Converts this GDimension to its string representation.

Overrides:

toString in class java.lang.Object

Returns:

A string representation of this dimension object
