Constructor Summary

Constructors

Constructor	Description
ImageCapabilities(boolean accelerated)	Creates a new object for specifying image capabilities.

Method Summary

Modifier and Type	Method	Description
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	isAccelerated()	Returns true if the object whose capabilities are encapsulated in this ImageCapabilities can be or is accelerated.
boolean	isTrueVolatile()	Returns true if the VolatileImage described by this ImageCapabilities can lose its surfaces.

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

Modifier and Type	Method	Description
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.

Constructor Details

ImageCapabilities

public ImageCapabilities(boolean accelerated)

Creates a new object for specifying image capabilities.

Parameters:

accelerated - whether or not an accelerated image is desired

Method Details

isAccelerated

public boolean isAccelerated()

Returns true if the object whose capabilities are encapsulated in this ImageCapabilities can be or is accelerated.

Returns:

whether or not an image can be, or is, accelerated. There are various platform-specific ways to accelerate an image, including pixmaps, VRAM, AGP. This is the general acceleration method (as opposed to residing in system memory).

isTrueVolatile

public boolean isTrueVolatile()

Returns true if the VolatileImage described by this ImageCapabilities can lose its surfaces.

Returns:

whether or not a volatile image is subject to losing its surfaces at the whim of the operating system.

clone

public Object 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.

Overrides:

clone in class Object

Returns:

a copy of this ImageCapabilities object.
