示例1: replaceSurfaceData
import sun.java2d.ScreenUpdateManager; //导入方法依赖的package包/类
/**
* Multi-buffer version of replaceSurfaceData. This version is called
* by createBuffers(), which needs to acquire the same locks in the same
* order, but also needs to perform additional functions inside the
* locks.
*/
public void replaceSurfaceData(int newNumBackBuffers,
BufferCapabilities caps)
{
SurfaceData oldData = null;

synchronized(((Component)target).getTreeLock()) {
