escape
Escape quotes, \, /, \r, \n, \b, \f, \t and other control characters (U+0000 through U+001F). It's the same as JSONValue.escape() only for compatibility here.- See Also:

toJSONString
Convert a map to JSON text. The result is a JSON object. If this map is also a JSONAware, JSONAware specific behaviours will be omitted at this top level.- Parameters:
map
-- Returns:
- JSON text, or "null" if map is null.
