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

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

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.

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.

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.

writeBoolean

 public abstract void writeBoolean(boolean v) throws IOException

Writes a boolean value to this output stream.

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

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.

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.

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.

writeInt

 public abstract void writeInt(int v) throws IOException

Writes an int value to this output stream.

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

writeLong

 public abstract void writeLong(long v) throws IOException

Writes a long value to this output stream.

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

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.

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.

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.

writeChars

 public abstract void writeChars(String s) throws IOException
