Interface ObjectOutput

All Superinterfaces:

DataOutput

public interface ObjectOutput
extends DataOutput

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.

Method Detail

write

void write(int b)
    throws IOException

This method writes the specified byte to the output stream.

Specified by:

write in interface DataOutput

Parameters:

b - The byte to write.

Throws:

IOException - If an error occurs.

write

void write(byte[] buf)
    throws IOException

This method writes all the bytes in the specified byte array to the output stream.

Specified by:

write in interface DataOutput

Parameters:

buf - The array of bytes to write.

Throws:

IOException - If an error occurs.

write

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.

Specified by:

write in interface DataOutput

Parameters:

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.

Throws:

IOException - If an error occurs.

writeObject

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

Parameters:

obj - The object to write

Throws:

IOException - If an error occurs

flush

void flush()
    throws IOException

This method causes any buffered data to be flushed out to the underlying stream

Throws:

IOException - If an error occurs

close

void close()
    throws IOException

This method closes the underlying stream.

Throws:

IOException - If an error occurs
