• Method Detail

  • writeObject

    void writeObject(Object obj)
     throws IOException 

    Write an object to the underlying storage or stream. The class that implements this interface defines how the object is written.

    Parameters:

    obj - the object to be written

    Throws:

    IOException - Any of the usual Input/Output related exceptions.

  • write

    void write(int b)
     throws IOException 

    Writes a byte. This method will block until the byte is actually written.

    Specified by:

    write in interface DataOutput

    Parameters:

    b - the byte

    Throws:

    IOException - If an I/O error has occurred.

  • write

    void write(byte[] b)
     throws IOException 

    Writes an array of bytes. This method will block until the bytes are actually written.

    Specified by:

    write in interface DataOutput

    Parameters:

    b - the data to be written

    Throws:

    IOException - If an I/O error has occurred.

  • write

    void write(byte[] b,
     int off,
     int len)
     throws IOException 

    Writes a sub array of bytes.

    Specified by:

    write in interface DataOutput

    Parameters:

    b - the data to be written

    off - the start offset in the data

    len - the number of bytes that are written

    Throws:

    IOException - If an I/O error has occurred.

  • flush

    void flush()
     throws IOException 

    Flushes the stream. This will write any buffered output bytes.

    Throws:

    IOException - If an I/O error has occurred.

  • close

    void close()
     throws IOException 

    Closes the stream. This method must be called to release any resources associated with the stream.

    Specified by:

    close in interface AutoCloseable

    Throws:

    IOException - If an I/O error has occurred.
