示例1: testSetByteArray
import sun.misc.Unsafe; //导入方法依赖的package包/类
private static void testSetByteArray(Unsafe unsafe) throws Exception {
System.out.println("Testing setMemory() for byte[]...");
byte[] b = new byte[BUFFER_SIZE];
for (int i = 0; i < N; i++) {
set(b, 0, BUFFER_SIZE, FILLER);
int ofs = random.nextInt(BUFFER_SIZE / 2);
int len = random.nextInt(BUFFER_SIZE / 2);
int val = random.nextInt(256);
unsafe.setMemory(b, Unsafe.ARRAY_BYTE_BASE_OFFSET + ofs, len, (byte)val);
check(b, 0, ofs - 1, FILLER);
check(b, ofs, len, val);
check(b, ofs + len, BUFFER_SIZE - (ofs + len), FILLER);
}
