Method Detail

create

public static JsonObject create()

parse

public static JsonObject parse(Reader reader)
                        throws JsonException,
                               IOException

Creates a JsonObject from a valid JSON string. This routine expects the first non-whitespace character to be '{', then reads a single encoded object from the Reader and leaves the reader positioned after the last '}' character.

Parameters:

reader - Reader positioned to contain a JSON object encoded as a string.

Returns:

a valid JsonObject on success, throws exception on failure.

Throws:

JsonException - The input string is not in valid JSON format.

IOException - An IO error was encountered before all of the string could be read.
