  • Method Summary

    Modifier and Type Method Description
    void close()
    Flushes and closes both this printer and any underlying output stream to which it is attached.
    void endList()
    Prints the close parenthesis of an S-expression list.
    void flush()
    Flushes all formatted text to the underlying writer.
    void printAtom​(java.lang.String atom)
    Prints an atom.
    protected void startElement()  
    protected void startEveryList​(boolean unified)  
    void startList()
    Prints the open parenthesis of an S-expression list.
    void startUnifiedList()
    Prints the open parenthesis of an S-expression list, and requires that if a line break is required to separate any two elements of this list, then all elements of this list must be separated by a line break (optional operation).
