IndentedPrintWriter

public IndentedPrintWriter(java.io.Writer w,
                           int indent)

Create a new writer over the given one, with the given indentation value. The indentation charachter defaults to blank - use setIndentationChar() to set it differently if required.

Parameters:

w - the writer wrapped by this IndentationPrintWriter

indent - the indentation level

IndentedPrintWriter

public IndentedPrintWriter(java.io.OutputStream out,
                           int indent,
                           boolean autoFlush)

Create a new writer over the given stream, with the given indentation value. The indentation charachter defaults to blank - use setIndentationChar() to set it differently if required.

Parameters:

out - the stream wrapped by this IndentationPrintWriter

indent - the indentation level

autoFlush - if true, the println() methods will flush the output buffer

IndentedPrintWriter

public IndentedPrintWriter(java.io.OutputStream out,
                           int indent)

Parameters:

out - the stream wrapped by this IndentationPrintWriter

indent - the indentation level

setIndentation

public void setIndentation(int indent)

Sets the current indentation level

Parameters:

indent - the desired indentation level

incIndentation

public void incIndentation(int level)

Increment the current indentation level of the given level.

Parameters:

level - the indentation level to be incremented

decIndentation

public void decIndentation(int level)

setIndentationChar

public void setIndentationChar(char c)

Set the charachter used to indent to the given character

Parameters:

c - the charachter to use for indentation

getIndentationChar

public char getIndentationChar()

Return the charachter used to indent to the given character

Returns:

the charachter to use for indentation

write

public void write(java.lang.String s,
                  int off,
                  int len)

Write a substring of a string, of given length from a given offset

Overrides:

write in class java.io.PrintWriter

write

public void write(int c)

Write a character

Overrides:

write in class java.io.PrintWriter

write

public void write(char[] buf,
                  int off,
