Interface ObjectOutput
- DataOutput
- ObjectOutputStream
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.
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 | writeObject(Object obj)- This method writes a object instance to a stream.
|
write, write, write, writeBoolean, writeByte, writeBytes, writeChar, writeChars, writeDouble, writeFloat, writeInt, writeLong, writeShort, writeUTF |
close
public void close()
throws IOException This method closes the underlying stream.
flush
public void flush()
throws IOException This method causes any buffered data to be flushed out to the underlying
stream
write
public void write(byte[] buf)
throws IOException This method writes all the bytes in the specified byte array to the
output stream.
- write in interface DataOutput
buf - The array of bytes to write.
write
public void write(byte[] buf,
int offset,
int len)
throws IOException This method writes len bytes from the specified array
starting at index offset into that array.
- write in interface DataOutput
buf - The byte array to write from.offset - The index into the byte array to start writing from.len - The number of bytes to write.
writeObject
public void writeObject(Object obj)
throws IOException This method writes a object instance to a stream. The format of the
data written is determined by the actual implementation of this method
obj - The object to write
