Parameters:

json - the JSON-encoded data

charset - the charset of the data

Returns:

an input stream that strips comments from json data provided as an input stream.

stripComments

public static Reader stripComments(InputStream json)

Parameters:

json - the JSON-encoded data

Returns:

a String with comments stripped from the provided json data.

stripComments

public static Reader stripComments(Reader json)

Parameters:

json - the JSON-encoded data

Returns:

a reader that strips comments from json data provided as a reader.

stringifyJavascriptObject

public static String stringifyJavascriptObject(Object object)

Converts the provided javascript object to JSON string.

If the object is a Map instance, it is stringified as key-value pairs, if it is a list, it is stringified as a list, otherwise the object is merely converted to string using the toString() method.

Parameters:

object - the object to stringify.

Returns:

the object as a JSON string

toModelNode
