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.

See Also:
DataInput, DataOutputStream

Method Index

 o write(byte[])
Writes b.length bytes from the specified byte array to this output stream.
 o write(byte[], int, int)
Writes len bytes from the specified byte array starting at offset off to this output stream.
 o write(int)
Writes the specified byte to this data output stream.
 o writeBoolean(boolean)
Writes a boolean value to this output stream.
 o writeByte(int)
Writes an 8-bit value to this output stream.
 o writeBytes(String)
Writes a string to this output stream.
 o writeChar(int)
Writes a char value to this output stream.
 o writeChars(String)
Writes a string to this output stream.
 o writeDouble(double)
Writes a double value to this output stream.
 o writeFloat(float)
Writes a float value to this output stream.
 o writeInt(int)
Writes an int value to this output stream.
 o writeLong(long)
Writes a long value to this output stream.
 o writeShort(int)
Writes a 16-bit value to this output stream.
 o writeUTF(String)
Writes a Unicode string by encoding it using modified UTF-8 format.

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 boolean to be written.
Throws: IOException
if an I/O error occurs.
 o writeByte
 public abstract void writeByte(int v) throws IOException
Writes an 8-bit value to this output stream.

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.
 o writeChar
 public abstract void writeChar(int v) throws IOException
Writes a char value to this output stream.

Parameters:
v - the char value to be written.
Throws: IOException
if an I/O error occurs.
 o writeInt
 public abstract void writeInt(int v) throws IOException

if an I/O error occurs.
 o writeFloat
 public abstract void writeFloat(float v) throws IOException
Writes a float value to this output stream.

Parameters:
v - the float value to be written.
Throws: IOException
if an I/O error occurs.
 o writeDouble
 public abstract void writeDouble(double v) throws IOException
Writes a double value to this output stream.

Parameters:
v - the double value to be written.
Throws: IOException
if an I/O error occurs.
 o writeBytes
 public abstract void writeBytes(String s) throws IOException
Writes a string to this output stream.

Parameters:
s - the string of bytes to be written.
Throws: IOException
if an I/O error occurs.
 o writeChars
 public abstract void writeChars(String s) throws IOException
Writes a string to this output stream.

Parameters:
s - the string value to be written.
Throws: IOException
if an I/O error occurs.
 o writeUTF
 public abstract void writeUTF(String str) throws IOException
Writes a Unicode string by encoding it using modified UTF-8 format.

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