BufferCapabilities
public BufferCapabilities(ImageCapabilities frontCaps, ImageCapabilities backCaps, BufferCapabilities.FlipContents flipContents) Creates a new object for specifying buffering capabilities- Parameters:
frontCaps
- the capabilities of the front buffer; cannot benull
backCaps
- the capabilities of the back and intermediate buffers; cannot benull
flipContents
- the contents of the back buffer after page-flipping,null
if page flipping is not used (implies blitting)- Throws:
IllegalArgumentException
- if frontCaps or backCaps arenull
-
-
Method Details
-
getFrontBufferCapabilities
- Returns:
- the image capabilities of the front (displayed) buffer
-
getBackBufferCapabilities
- Returns:
- the image capabilities of all back buffers (intermediate buffers are considered back buffers)
-
isPageFlipping
public boolean isPageFlipping()- Returns:
- 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
returnsnull
-
getFlipContents
- Returns:
- the resulting contents of the back buffer after page-flipping.
This value is
null
when theisPageFlipping
returnsfalse
, implying blitting. It can be one ofFlipContents.UNDEFINED
(the assumed default),FlipContents.BACKGROUND
,FlipContents.PRIOR
, orFlipContents.COPIED
. - See Also:
-
isFullScreenRequired
public boolean isFullScreenRequired()- Returns:
- 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:
-
isMultiBufferAvailable
public boolean isMultiBufferAvailable()- Returns:
- 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).

clone
Description copied from class:Object
Answers a new instance of the same class as the receiver, whose slots have been filled in with the values in the slots of the receiver.Classes which wish to support cloning must specify that they implement the Cloneable interface, since the native implementation checks for this.
