Interface java.io.DataOutput

public interface DataOutput
The data output interface is implemented by streams that can write primitive Java data types to an output stream in a machine-independent manner.

Methods

 o write
 public abstract void write(int b) throws IOException
Writes the specified byte to this data output stream.

Parameters:
b - the byte to be written.
Throws: IOException
if an I/O error occurs.
 o write
 public abstract void write(byte b[]) throws IOException
Writes b.length bytes from the specified byte array to this output stream.

Parameters:
b - the data.
Throws: IOException
if an I/O error occurs.
 o write
 public abstract void write(byte b[],
                            int off,
                            int len) throws IOException
Writes len bytes from the specified byte array starting at offset off to this output stream.

Parameters:
b - the data.
off - the start offset in the data.
len - the number of bytes to write.
Throws: IOException
if an I/O error occurs.
 o writeBoolean
 public abstract void writeBoolean(boolean v) throws IOException

Parameters:
v - the byte value to be written.
Throws: IOException
if an I/O error occurs.
 o writeShort
 public abstract void writeShort(int v) throws IOException
Writes a 16-bit value to this output stream.

Parameters:
v - the short value to be written.
Throws: IOException
if an I/O error occurs.
