-
space_before: a string that is put before a : pair delimiter (default: ”),
-
object_nl: a string that is put at the end of a
JSONobject (default: ”), -
array_nl: a string that is put at the end of a
JSONarray (default: ”), -
allow_nan: true if NaN, Infinity, and -Infinity should be generated, otherwise an exception is thrown, if these values are encountered. This options defaults to false.
-
ascii_only: true if only ASCII characters should be generated. This option defaults to false.
-
