write

public void write(java.lang.String s)

Description copied from class: CodeWriter

Print the string s verbatim on the output stream.

Overrides:

write in class CodeWriter

newline

public void newline(int n)

Description copied from class: CodeWriter

Like newline(), but forces a newline with a specified indentation.

allowBreak

public void allowBreak(int n)

Description copied from class: CodeWriter

The most common use of "allowBreak": level 1, with an alternative of a single space.

Overrides:

allowBreak in class CodeWriter

Parameters:

n - the indentation relative to the current block.

allowBreak

public void allowBreak(int n,
                       java.lang.String alt)

Overrides:

allowBreak in class CodeWriter

begin

public void begin(int n)

Description copied from class: CodeWriter

Start a new block with a relative indentation of n characters.

A block is a formatting unit. The formatting algorithm will try to put the whole block in one line unless

• there is a level-0 break in the block, or
• the block cannot fit in one line.

If either of the two conditions is satisfied, the formatting algorithm will break the block into lines by generating newlines for some of the inserted breaks. The first line is printed at the current cursor position pos, all the following lines are printed at the position pos+n.

Overrides:

begin in class CodeWriter

Parameters:

n - the number of characters increased on indentation (relative to the current position) for all lines in the block. Requires: n >= 0.

toString

public java.lang.String toString()

Description copied from class: CodeWriter

Return a readable representation of all the structured input given to the CodeWriter since the last flush.

Overrides:
