示例1: createSurfaceManager
import java.awt.ImageCapabilities; //导入方法依赖的package包/类
protected VolatileSurfaceManager createSurfaceManager(Object context,
ImageCapabilities caps)
{
/**
* Platform-specific SurfaceManagerFactories will return a
* manager suited to acceleration on each platform. But if
* the user is asking for a VolatileImage from a BufferedImageGC,
* then we need to return the appropriate unaccelerated manager.
* Note: this could change in the future; if some platform would
* like to accelerate BIGC volatile images, then this special-casing
* of the BIGC graphicsConfig should live in platform-specific
* code instead.
* We do the same for a Printer Device, and if user requested an
* unaccelerated VolatileImage by passing the capabilities object.
