Class DisplayMode

java.lang.Object
  extended byjava.awt.DisplayMode

public final class DisplayMode
extends Object

The DisplayMode class encapsulates the bit depth, height, width, and refresh rate of a GraphicsDevice. Display modes are hardware-dependent and may not always be available.

Since:
1.4
See Also:
GraphicsDevice

Field Summary
static int BIT_DEPTH_MULTI
          Value of the bit depth if multiple bit depths are supported in this dislay 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.

BIT_DEPTH_MULTI

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

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

getWidth

public int getWidth()
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.
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.
See Also:
REFRESH_RATE_UNKNOWN

equals

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

hashCode

public int hashCode()
Description copied from class: Object
Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable.

The general contract of hashCode is:

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)

Overrides:
hashCode in class Object
Returns:
a hash code value for this object

Object.equals(java.lang.Object), Hashtable
