the class CodeFormatterUtil method format2.

/**
 * Creates edits that describe how to format the given string.
 * The given node is used to infer the kind to use to format the string.
 * Consider to use {@link #format2(int, String, int, String, Map)} if the kind is already known.
 * Returns <code>null</code> if the code could not be formatted for the given kind.
 *
 * @param node
 *        Use to infer the kind of the code snippet to format.
 * @param source
 *        The source to format
 * @param indentationLevel
 *        The initial indentation level, used to shift left/right the entire source fragment.
 *        An initial indentation level of zero or below has no effect.
 * @param lineSeparator
 *        The line separator to use in formatted source,
 *        if set to <code>null</code>, then the platform default one will be used.
 * @param options
 *        The options map to use for formatting with the default code formatter.
 *        Recognized options are documented on {@link JavaCore#getDefaultOptions()}.
 *        If set to <code>null</code>, then use the current settings from {@link JavaCore#getOptions()}.
 * @return an TextEdit describing the changes required to format source
 * @throws IllegalArgumentException
 *         If the offset and length are not inside the string, a IllegalArgumentException is thrown.
