public interface ObjectOutput
This interface extends DataOutput
to provide the additional
facility of writing object instances to a stream. It also adds some
additional methods to make the interface more
OutputStream
like.
DataOutput
Method Summary | |
---|---|
void |
close()
This method closes the underlying stream. |
void |
flush()
This method causes any buffered data to be flushed out to the underlying stream |
void |
write(byte[] buf)
This method writes all the bytes in the specified byte array to the output stream. |
void |
write(byte[] buf,
int offset,
int len)
This method writes len bytes from the specified array
starting at index offset into that array. |
void |
write(int b)
This method writes the specified byte to the output stream. |
void |
