Class GraphicsConfigTemplate

java.lang.Object

java.awt.GraphicsConfigTemplate

All Implemented Interfaces:

Serializable

public abstract class GraphicsConfigTemplate
extends Object
implements Serializable

The GraphicsConfigTemplate class is used to obtain a valid GraphicsConfiguration. A user instantiates one of these objects and then sets all non-default attributes as desired. The GraphicsDevice.getBestConfiguration(GraphicsConfigTemplate) method found in the GraphicsDevice class is then called with this GraphicsConfigTemplate. A valid GraphicsConfiguration is returned that meets or exceeds what was requested in the GraphicsConfigTemplate.

Since:

1.2

Methods declared in class Object

clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait

Modifier and Type	Method	Description
protected Object	clone()	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.
boolean	equals(Object o)	Compares the argument to the receiver, and answers true if they represent the same object using a class specific comparison.
protected void	finalize()	Deprecated, for removal: This API element is subject to removal in a future version. May cause performance issues, deadlocks and hangs.
final Class<? extends Object>	getClass()	Answers the unique instance of java.lang.Class which represents the class of the receiver.
int	hashCode()	Answers an integer hash code for the receiver.
final void	notify()	Causes one thread which is waiting on the receiver to be made ready to run.
final void	notifyAll()	Causes all threads which are waiting on the receiver to be made ready to run.
String	toString()	Answers a string containing a concise, human-readable description of the receiver.
final void	wait()	Causes the thread which sent this message to be made not ready to run pending some change in the receiver (as indicated by notify or notifyAll).
final void	wait(long time)	Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout.
final void	wait(long time, int frac)	Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout.

Field Details

REQUIRED

public static final int REQUIRED

Value used for "Enum" (Integer) type. States that this feature is required for the GraphicsConfiguration object. If this feature is not available, do not select the GraphicsConfiguration object.

See Also:

• Constant Field Values

PREFERRED

public static final int PREFERRED

Value used for "Enum" (Integer) type. States that this feature is desired for the GraphicsConfiguration object. A selection with this feature is preferred over a selection that does not include this feature, although both selections can be considered valid matches.

See Also:

• Constant Field Values

UNNECESSARY

public static final int UNNECESSARY

Value used for "Enum" (Integer) type. States that this feature is not necessary for the selection of the GraphicsConfiguration object. A selection without this feature is preferred over a selection that includes this feature since it is not used.

• Constant Field Values

Constructor Details

GraphicsConfigTemplate

public GraphicsConfigTemplate()

This class is an abstract class so only subclasses can be instantiated.

Method Details

getBestConfiguration

public abstract GraphicsConfiguration getBestConfiguration(GraphicsConfiguration[] gc)

Returns the "best" configuration possible that passes the criteria defined in the GraphicsConfigTemplate.

Parameters:

gc - the array of GraphicsConfiguration objects to choose from.

Returns:

a GraphicsConfiguration object that is the best configuration possible.

• GraphicsConfiguration

isGraphicsConfigSupported

public abstract boolean isGraphicsConfigSupported(GraphicsConfiguration gc)

Returns a boolean indicating whether or not the specified GraphicsConfiguration can be used to create a drawing surface that supports the indicated features.

Parameters:

gc - the GraphicsConfiguration object to test

Returns:

true if this GraphicsConfiguration object can be used to create surfaces that support the indicated features; false if the GraphicsConfiguration can not be used to create a drawing surface usable by this Java(tm) API.
