Class DisplayMode

java.lang.Object
  extended by java.awt.DisplayMode

public final class DisplayMode
extends Object

The DisplayMode class encapsulates the bit depth, height, width, and refresh rate of a GraphicsDevice. The ability to change graphics device's display mode is platform- and configuration-dependent and may not always be available (see GraphicsDevice.isDisplayChangeSupported()).

For more information on full-screen exclusive mode API, see the Full-Screen Exclusive Mode API Tutorial.

Since:
1.4
See Also:
GraphicsDevice, GraphicsDevice.isDisplayChangeSupported(), GraphicsDevice.getDisplayModes(), GraphicsDevice.setDisplayMode(java.awt.DisplayMode)

Field Summary
static int BIT_DEPTH_MULTI
          Value of the bit depth if multiple bit depths are supported in this display mode.
static int REFRESH_RATE_UNKNOWN
          Value of the refresh rate if not known.
 
Constructor Summary
DisplayMode(int width, int height, int bitDepth, int refreshRate)
          Create a new display mode object with the supplied parameters.
 
Method Summary
 boolean equals(DisplayMode dm)
          Returns whether the two display modes are equal.
 boolean equals(Object dm)
          equals compares this object to another object.
 int getBitDepth()
          Returns the bit depth of the display, in bits per pixel.
 int getHeight()
          Returns the height of the display, in pixels.
 int getRefreshRate()
          Returns the refresh rate of the display, in hertz.
 int getWidth()
          Returns the width of the display, in pixels.

Field Detail

BIT_DEPTH_MULTI

public static final int BIT_DEPTH_MULTI
Value of the bit depth if multiple bit depths are supported in this display mode.

getBitDepth(), Constant Field Values

REFRESH_RATE_UNKNOWN

public static final int REFRESH_RATE_UNKNOWN
Value of the refresh rate if not known.

Constructor Detail

DisplayMode

public DisplayMode(int width,
                   int height,
                   int bitDepth,
                   int refreshRate)
Create a new display mode object with the supplied parameters.

Parameters:
width - the width of the display, in pixels
height - the height of the display, in pixels
bitDepth - the bit depth of the display, in bits per pixel. This can be BIT_DEPTH_MULTI if multiple bit depths are available.
refreshRate - the refresh rate of the display, in hertz. This can be REFRESH_RATE_UNKNOWN if the information is not available.
See Also:
BIT_DEPTH_MULTI, REFRESH_RATE_UNKNOWN
Method Detail

getHeight

public int getHeight()
Returns the height of the display, in pixels.

Returns:
the height of the display, in pixels

getWidth

public int getWidth()
Returns the width of the display, in pixels.

Returns:
the width of the display, in pixels

getBitDepth

public int getBitDepth()
Returns the bit depth of the display, in bits per pixel. This may be BIT_DEPTH_MULTI if multiple bit depths are supported in this display mode.

Returns:
the bit depth of the display, in bits per pixel.
See Also:
BIT_DEPTH_MULTI

getRefreshRate

public int getRefreshRate()
Returns the refresh rate of the display, in hertz. This may be REFRESH_RATE_UNKNOWN if the information is not available.

Returns:
the refresh rate of the display, in hertz.
See Also:
REFRESH_RATE_UNKNOWN

equals

public boolean equals(DisplayMode dm)
Returns whether the two display modes are equal.

Returns:
whether the two display modes are equal

equals

public boolean equals(Object dm)
equals compares this object to another object.

Equals must be symmetric (a.equals(b) == b.equals(a)), reflexive (a.equals(a)==true) and transitive (a.equals(b) && b.equals(c) IMPLIES (a.equals(c))) and not change over time (a.equals(b) == a.equals(b)). a.equals(null) should always return false.

If a.equals(b) is true for two objects a and b, then a.hashCode()==b.hashCode() must hold.

The default implementation of equals returns this==other.

Overrides:
equals in class Object
Parameters:
dm - the other object.
Returns:
if this and other are considered equal.

hashCode

public int hashCode()
hashCode returns a hash code for this object. The hash code must be equal for two objects a and b if a.equals(b) is true.

The default implementation returns System.identityHashCode(this).

Overrides:
hashCode in class Object
Returns:
a hash code value.
