public class DefaultCapabilitiesChooser extends Object implements CapabilitiesChooser
The default implementation of the CapabilitiesChooser interface, which provides consistent visual
selection behavior across platforms. The precise algorithm is
deliberately left loosely specified. Some properties are:
| Constructor and Description |
|---|
DefaultCapabilitiesChooser() |
| Modifier and Type | Method and Description |
|---|---|
int |
chooseCapabilities(CapabilitiesImmutable desired,
List<? extends CapabilitiesImmutable> available,
int windowSystemRecommendedChoice)
Chooses the index (0..available.length - 1) of the
Capabilities most closely matching the desired one from the
list of all supported. |
public int chooseCapabilities(CapabilitiesImmutable desired, List<? extends CapabilitiesImmutable> available, int windowSystemRecommendedChoice)
CapabilitiesChooserCapabilities most closely matching the desired one from the
list of all supported. Some of the entries in the
available array may be null; the chooser must
ignore these. The windowSystemRecommendedChoice
parameter may be provided to the chooser by the underlying
window system; if this index is valid, it is recommended, but
not necessarily required, that the chooser select that entry.
Note: this method is called automatically by the
GraphicsConfigurationFactory.chooseGraphicsConfiguration(javax.media.nativewindow.CapabilitiesImmutable, javax.media.nativewindow.CapabilitiesImmutable, javax.media.nativewindow.CapabilitiesChooser, javax.media.nativewindow.AbstractGraphicsScreen, int) method
when an instance of this class is passed in to it.
It should generally not be
invoked by users directly, unless it is desired to delegate the
choice to some other CapabilitiesChooser object.
