Its + * external form is a string wrapped in curly braces with colons between the + * names and values, and commas between the values and names. The internal form + * is an object having get and opt methods for + * accessing the values by name, and put methods for adding or + * replacing values by name. The values can be any of these types: + * Boolean, JSONArray, JSONObject, + * Number, String, or the JSONObject.NULL + * object. A JSONObject constructor can be used to convert an external form + * JSON text into an internal form whose values can be retrieved with the + * get and opt methods, or to convert values into a + * JSON text using the put and toString methods. + * A get method returns a value if one can be found, and throws an + * exception if one cannot be found. An opt method returns a + * default value instead of throwing an exception, and so is useful for + * obtaining optional values. + *

+ * The generic get() and opt() methods return an + * object, which you can cast or query for type. There are also typed + * get and opt methods that do type checking and type + * coercion for you. + *

+ * The put methods adds values to an object. For example, 

+ *     myString = new JSONObject().put("JSON", "Hello, World!").toString();
+ * produces the string {"JSON": "Hello, World"}. + *

+ * The texts produced by the toString methods strictly conform to + * the JSON syntax rules. + * The constructors are more forgiving in the texts they will accept: + *

    + *
  • An extra , (comma) may appear just + * before the closing brace.
    • + *
  • Strings may be quoted with ' (single + * quote).
    • + *
  • Strings do not need to be quoted at all if they do not begin with a quote + * or single quote, and if they do not contain leading or trailing spaces, + * and if they do not contain any of these characters: + * { } [ ] / \ : , = ; # and if they do not look like numbers + * and if they are not the reserved words true, + * false, or null.
    • + *
  • Keys can be followed by = or => as well as + * by :.

+ * On Windows XP sp1 with 1.4.2_04 and later ;), this encoder and decoder is about 10 times faster + * on small arrays (10 - 1000 bytes) and 2-3 times as fast on larger arrays (10000 - 1000000 bytes) + * compared to sun.misc.Encoder()/Decoder().

+ * + * On byte arrays the encoder is about 20% faster than Jakarta Commons Base64 Codec for encode and + * about 50% faster for decoding large arrays. This implementation is about twice as fast on very small + * arrays (< 30 bytes). If source/destination is a String this + * version is about three times as fast due to the fact that the Commons Codec result has to be recoded + * to a String from byte[], which is very expensive.

+ * + * This encode/decode algorithm doesn't create any temporary arrays as many other codecs do, it only + * allocates the resulting array. This produces less garbage and it is possible to handle arrays twice + * as large as algorithms that create a temporary array. (E.g. Jakarta Commons Codec). It is unknown + * whether Sun's sun.misc.Encoder()/Decoder() produce temporary arrays but since performance + * is quite low it probably does.

+ * + * The encoder produces the same output as the Sun one except that the Sun's encoder appends + * a trailing line separator if the last character isn't a pad. Unclear why but it only adds to the + * length and is probably a side effect. Both are in conformance with RFC 2045 though.
+ * Commons codec seem to always att a trailing line separator.

+ * + * Note! + * The encode/decode method pairs (types) come in three versions with the exact same algorithm and + * thus a lot of code redundancy. This is to not create any temporary arrays for transcoding to/from different + * format types. The methods not used can simply be commented out.

+ * + * There is also a "fast" version of all decode methods that works the same way as the normal ones, but + * har a few demands on the decoded input. Normally though, these fast verions should be used if the source if + * the input is known and it hasn't bee tampered with.
