Class BufferedOutput

java.lang.Object
  java.io.OutputStream
      java.io.FilterOutputStream
          java.io.BufferedOutputStream
              FlexOr.io.BufferedOutput

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable

public class BufferedOutput
extends java.io.BufferedOutputStream

Constructor Summary

BufferedOutput(java.lang.String fileName)
Creating an instance of BufferedOutput opens the named file.

Method Summary

int	getCharCount()
int	getLineLength()
int	getTabStopDist()
void	setTabStopDist(int tabStopDist)
void	write(byte[] buffer, int offset, int count) ---------------------------
void	write(int theChar) ---------------------------
void	writeInteger(int integer) We make use of the standard Java conversion routine combined with our custom output of strings.
void	writeInteger(int integer, int width) Require: String.valueOf(integer).length <= width Output an integer in a specified width of field.
void	writeNewline() When a new line character is emitted we want to reset lineLength.
void	writeNoCount(byte[] buffer, int offset, int count) Occasionally we need to output to the current line without adding to the line length (for example, when markup tags are output).

Constructor Detail

BufferedOutput

public BufferedOutput(java.lang.String fileName)
               throws java.io.IOException

Creating an instance of BufferedOutput opens the named file. There is no open required by the user. In the OO paradigm opening a file is analogous to creating a new object unlike procedural paradigm where the same variables are reused for each file. ---------------------------

Throws:

java.io.IOException

Method Detail

getCharCount

public int getCharCount()

getLineLength

public int getLineLength()

getTabStopDist

public int getTabStopDist()

setTabStopDist

public void setTabStopDist(int tabStopDist)

write

public void write(int theChar)

---------------------------

Overrides:

write in class java.io.BufferedOutputStream

writeNewline

public void writeNewline()

When a new line character is emitted we want to reset lineLength. Again, having a special purpose parameterless call is more efficient and descriptive in application programs. ---------------------------

write

public void write(byte[] buffer,
                  int offset,
                  int count)

---------------------------

Overrides:

write in class java.io.BufferedOutputStream

writeNoCount

public void writeNoCount(byte[] buffer,
                         int offset,
                         int count)

Occasionally we need to output to the current line without adding to the line length (for example, when markup tags are output). The following operation prints directly to the output file. The total number of output characters is incremented but the line length is not. ---------------------------

writeInteger

public void writeInteger(int integer)

We make use of the standard Java conversion routine combined with our custom output of strings. ---------------------------

writeInteger

public void writeInteger(int integer,
                         int width)

Require: String.valueOf(integer).length <= width Output an integer in a specified width of field. ---------------------------
