Field Summary

private ImageCapabilities	backCaps
private java.awt.BufferCapabilities.FlipContents	flipContents
private ImageCapabilities	frontCaps

Constructor Summary

BufferCapabilities(ImageCapabilities frontCaps, ImageCapabilities backCaps, java.awt.BufferCapabilities.FlipContents flipContents)
Suppressed: Creates a new object for specifying buffering capabilities

Method Summary

Object	clone() Suppressed: @return a copy of this BufferCapabilities object.
ImageCapabilities	getBackBufferCapabilities() Enabled: @return the image capabilities of all back buffers (intermediate buffers are considered back buffers)
java.awt.BufferCapabilities.FlipContents	getFlipContents() Enabled: @return the resulting contents of the back buffer after page-flipping.
ImageCapabilities	getFrontBufferCapabilities() Enabled: @return the image capabilities of the front (displayed) buffer
boolean	isFullScreenRequired() Enabled: @return whether page flipping is only available in full-screen mode.
boolean	isMultiBufferAvailable() Enabled: @return whether or not page flipping can be performed using more than two buffers (one or more intermediate buffers as well as the front and back buffer).
boolean	isPageFlipping() Enabled: @return whether or not the buffer strategy uses page flipping; a set of buffers that uses page flipping can swap the contents internally between the front buffer and one or more back buffers by switching the video pointer (or by copying memory internally).

Constructor Detail

BufferCapabilities

public BufferCapabilities(ImageCapabilities frontCaps,
                          ImageCapabilities backCaps,
                          java.awt.BufferCapabilities.FlipContents flipContents)

Suppressed: Creates a new object for specifying buffering capabilities

Parameters:

frontCaps - the capabilities of the front buffer; cannot be null

backCaps - the capabilities of the back and intermediate buffers; cannot be null

flipContents - the contents of the back buffer after page-flipping, null if page flipping is not used (implies blitting)

Method Detail

getFrontBufferCapabilities

public ImageCapabilities getFrontBufferCapabilities()

Enabled: @return the image capabilities of the front (displayed) buffer

getBackBufferCapabilities

public ImageCapabilities getBackBufferCapabilities()

Enabled: @return the image capabilities of all back buffers (intermediate buffers are considered back buffers)

isPageFlipping

public boolean isPageFlipping()

Enabled: @return whether or not the buffer strategy uses page flipping; a set of buffers that uses page flipping can swap the contents internally between the front buffer and one or more back buffers by switching the video pointer (or by copying memory internally). A non-flipping set of buffers uses blitting to copy the contents from one buffer to another; when this is the case, getFlipContents returns null

getFlipContents

public java.awt.BufferCapabilities.FlipContents getFlipContents()

Enabled: @return the resulting contents of the back buffer after page-flipping. This value is null when the isPageFlipping returns false, implying blitting. It can be one of FlipContents.UNDEFINED (the assumed default), FlipContents.BACKGROUND, FlipContents.PRIOR, or FlipContents.COPIED.

See Also:

isPageFlipping(), FlipContents.UNDEFINED, FlipContents.BACKGROUND, FlipContents.PRIOR, FlipContents.COPIED

isFullScreenRequired

public boolean isFullScreenRequired()

Enabled: @return whether page flipping is only available in full-screen mode. If this is true, full-screen exclusive mode is required for page-flipping.

See Also:

isPageFlipping(), GraphicsDevice.setFullScreenWindow(java.awt.Window)

isMultiBufferAvailable

public boolean isMultiBufferAvailable()

Enabled: @return whether or not page flipping can be performed using more than two buffers (one or more intermediate buffers as well as the front and back buffer).

See Also:

isPageFlipping()

clone

public Object clone()

Suppressed: @return a copy of this BufferCapabilities object.

Overrides:

clone in class Object

Returns:

a clone of this instance.
