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 <code>get</code> and <code>opt</code> methods for accessing the - * values by name, and <code>put</code> methods for adding or replacing values - * by name. The values can be any of these types: <code>Boolean</code>, - * <code>JSONArray</code>, <code>JSONObject</code>, <code>Number</code>, - * <code>String</code>, or the <code>JSONObject.NULL</code> 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 <code>get</code> and - * <code>opt</code> methods, or to convert values into a JSON text using the - * <code>put</code> and <code>toString</code> methods. A <code>get</code> method - * returns a value if one can be found, and throws an exception if one cannot be - * found. An <code>opt</code> method returns a default value instead of throwing - * an exception, and so is useful for obtaining optional values. - * <p> - * The generic <code>get()</code> and <code>opt()</code> methods return an - * object, which you can cast or query for type. There are also typed - * <code>get</code> and <code>opt</code> methods that do type checking and type - * coercion for you. The opt methods differ from the get methods in that they do - * not throw. Instead, they return a specified value, such as null. - * <p> - * The <code>put</code> methods add or replace values in an object. For example, - * - * <pre> - * myString = new JSONObject().put("JSON", "Hello, World!").toString(); - * </pre> - * - * produces the string <code>{"JSON": "Hello, World"}</code>. - * <p> - * The texts produced by the <code>toString</code> methods strictly conform to - * the JSON syntax rules. The constructors are more forgiving in the texts they - * will accept: - * <ul> - * <li>An extra <code>,</code> <small>(comma)</small> may appear just - * before the closing brace.</li> - * <li>Strings may be quoted with <code>'</code> <small>(single - * quote)</small>.</li> - * <li>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: - * <code>{ } [ ] / \ : , = ; #</code> and if they do not look like numbers and - * if they are not the reserved words <code>true</code>, <code>false</code>, or - * <code>null</code>.</li> - * <li>Keys can be followed by <code>=</code> or <code>=></code> as well as by - * <code>:</code>.</li> - * <li>Values can be followed by <code>;</code> <small>(semicolon)</small> as - * well as by <code>,</code> <small>(comma)</small>.</li> - * </ul> - * - * @author JSON.org - * @version 2012-07-02 - */ -public class JSONObject { - - /** - * JSONObject.NULL is equivalent to the value that JavaScript calls null, - * whilst Java's null is equivalent to the value that JavaScript calls - * undefined. - */ - private static final class Null { - - /** - * There is only intended to be a single instance of the NULL object, - * so the clone method returns itself. - * @return NULL. - */ - protected final Object clone() { - return this; - } - - /** - * A Null object is equal to the null value and to itself. - * @param object An object to test for nullness. - * @return true if the object parameter is the JSONObject.NULL object - * or null. - */ - public boolean equals(Object object) { - return object == null || object == this; - } - - /** - * Get the "null" string value. - * @return The string "null". - */ - public String toString() { - return "null"; - } - } - - - /** - * The map where the JSONObject's properties are kept. - */ - private final Map map; - - - /** - * It is sometimes more convenient and less ambiguous to have a - * <code>NULL</code> object than to use Java's <code>null</code> value. - * <code>JSONObject.NULL.equals(null)</code> returns <code>true</code>. - * <code>JSONObject.NULL.toString()</code> returns <code>"null"</code>. - */ - public static final Object NULL = new Null(); - - - /** - * Construct an empty JSONObject. - */ - public JSONObject() { - this.map = new HashMap(); - } - - - /** - * Construct a JSONObject from a subset of another JSONObject. - * An array of strings is used to identify the keys that should be copied. - * Missing keys are ignored. - * @param jo A JSONObject. - * @param names An array of strings. - */ - public JSONObject(JSONObject jo, String[] names) { - this(); - for (int i = 0; i < names.length; i += 1) { - try { - this.putOnce(names[i], jo.opt(names[i])); - } catch (Exception ignore) { - } - } - } - - - /** - * Construct a JSONObject from a JSONTokener. - * @param x A JSONTokener object containing the source string. - * @throws JSONException If there is a syntax error in the source string - * or a duplicated key. - */ - public JSONObject(JSONTokener x) throws JSONException { - this(); - char c; - String key; - - if (x.nextClean() != '{') { - throw x.syntaxError("A JSONObject text must begin with '{'"); - } - for (;;) { - c = x.nextClean(); - switch (c) { - case 0: - throw x.syntaxError("A JSONObject text must end with '}'"); - case '}': - return; - default: - x.back(); - key = x.nextValue().toString(); - } - -// The key is followed by ':'.
