BufferStrategy

java.lang.Object

public abstract class BufferStrategy extends Object

The BufferStrategy abstract class provides an opportunity to organize the buffers for a Canvas or Window. The BufferStrategy implementation depends on hardware and software limitations. These limitations are detectable through the capabilities object which can be obtained by the GraphicsConfiguration of the Canvas or Window.
