示例1: getShort
import org.apache.hadoop.hbase.util.ByteBufferUtils; //导入方法依赖的package包/类
private short getShort(int index, int itemIndex) {
ByteBuffer item = items[itemIndex];
int offsetInItem = index - this.itemBeginPos[itemIndex];
int remainingLen = item.limit() - offsetInItem;
if (remainingLen >= Bytes.SIZEOF_SHORT) {
return ByteBufferUtils.toShort(item, offsetInItem);
}
if (items.length - 1 == itemIndex) {
// means cur item is the last one and we wont be able to read a int. Throw exception
throw new BufferUnderflowException();
}
ByteBuffer nextItem = items[itemIndex + 1];
// Get available bytes from this item and remaining from next
short l = 0;
for (int i = offsetInItem; i < item.capacity(); i++) {
l = (short) (l << 8);
l = (short) (l ^ (ByteBufferUtils.toByte(item, i) & 0xFF));
}
