@staticmethod<EOL><INDENT>def inlineLiteralsUsing(cls):<DEDENT>
ParserElement._literalStringClass = cls<EOL>
Set class to be used for inclusion of string literals into a parser.

Example::

    # default literal class used is Literal
    integer = Word(nums)
    date_str = integer("year") + '/' + integer("month") + '/' + integer("day")

    date_str.parseString("1999/12/31")  # -> ['1999', '/', '12', '/', '31']


    # change to Suppress
    ParserElement.inlineLiteralsUsing(Suppress)
    date_str = integer("year") + '/' + integer("month") + '/' + integer("day")

    date_str.parseString("1999/12/31")  # -> ['1999', '12', '31']
