               throws IOException

Writes one byte to this stream.

Parameters:

value - a byte value to be written.

s - prefix to use if this write is logged. A value of null prevents logging altogether.

Throws:

IOException - if there was an IO error while writing

writeBoolean

public void writeBoolean(boolean value,
                         String s)
                  throws IOException

Writes a boolean value to this stream.

Parameters:

value - a boolean value to be written.

s - prefix to use if this write is logged. A value of null prevents logging altogether.

Throws:

IOException - if there was an IO error while writing

writeChar

public void writeChar(char value,
                      String s)
               throws IOException

Writes a char value to this stream.

Parameters:

value - a char value to be written.

s - prefix to use if this write is logged. A value of null prevents logging altogether.

Throws:

IOException - if there was an IO error while writing

writeShort

public void writeShort(short value,
                       String s)
                throws IOException

Writes a short value to this stream.

Parameters:

value - a short value to be written.

s - prefix to use if this write is logged. A value of null prevents logging altogether.

Throws:

IOException - if there was an IO error while writing

writeInt

public void writeInt(int value,
                     String s)
              throws IOException

Writes an int value to this stream.

Parameters:

value - an int value to be written.

s - prefix to use if this write is logged. A value of null prevents logging altogether.

Throws:

IOException - if there was an IO error while writing

writeLong

public void writeLong(long value,
                      String s)
               throws IOException

Writes a long value to this stream.

Parameters:

value - a long value to be written.

s - prefix to use if this write is logged. A value of null prevents logging altogether.

Throws:

IOException - if there was an IO error while writing

writeFloat

public void writeFloat(float value,
                       String s)
                throws IOException

Writes a float value to this stream.

Parameters:

value - a float value to be written.

s - prefix to use if this write is logged. A value of null prevents logging altogether.

Throws:

IOException - if there was an IO error while writing

writeDouble

public void writeDouble(double value,
                        String s)
                 throws IOException

Writes a double value to this stream.

Parameters:

value - a double value to be written.

s - prefix to use if this write is logged. A value of null prevents logging altogether.

Throws:

IOException - if there was an IO error while writing

writeString

public void writeString(String value,
                        String s)
                 throws IOException

Writes a string to the underlying output stream using UTF-8 encoding in a machine-independent manner.

First, four bytes are written to the output stream as if by the writeInt method giving the number of bytes to follow. This value is the number of bytes actually written out, not the length of the string. Following the length, each character of the string is output, in sequence, using the UTF-8 encoding for the character.

Parameters:

value - a string to be written.

s - prefix to use if this write is logged. A value of null prevents logging altogether.

Throws:

IOException - if there was an IO error while writing
