示例1: transferTo
import java.nio.channels.WritableByteChannel; //導入方法依賴的package包/類
public long transferTo(long position, long count,
WritableByteChannel target)
throws IOException
{
ensureOpen();
if (!target.isOpen())
throw new ClosedChannelException();
if (!readable)
throw new NonReadableChannelException();
if (target instanceof FileChannelImpl &&
!((FileChannelImpl)target).writable)
throw new NonWritableChannelException();
if ((position < 0) || (count < 0))
throw new IllegalArgumentException();
long sz = size();
if (position > sz)
return 0;
int icount = (int)Math.min(count, Integer.MAX_VALUE);
if ((sz - position) < icount)
icount = (int)(sz - position);
// Slow path for untrusted targets
return transferToArbitraryChannel(position, icount, target);
