Code modified for XDocReport (see "added by XDocReport" comment) :
- JSONObject extends HashMap
A JSONObject is an unordered collection of name/value pairs. 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 opt methods differ from the get methods in that they do not throw. Instead, they return a specified value, such as null.
The put methods add or replace values in 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 :.
- Values can be followed by ; (semicolon) as well as by , (comma).

```
public JSONObject(Object bean,
          boolean upperCaseFirstChar)
```
    Construct a JSONObject from an Object using bean getters. It reflects on all of the public methods of the object. For each of the methods with no parameters and a name starting with "get" or "is" followed by an uppercase letter, the method is invoked, and a key and the value returned from the getter method are put into the new JSONObject. The key is formed by removing the "get" or "is" prefix. If the second remaining character is not upper case, then the first character is converted to lower case. For example, if an object has a method named "getName", and if the result of calling object.getName() is "Larry Fine", then the JSONObject will contain "name": "Larry Fine".
    
    Parameters:
    bean - An object that has getter methods that should be used to make a JSONObject.
  - JSONObject
```
public JSONObject(Object object,
          String[] names)
```
    Construct a JSONObject from an Object, using reflection to find the public members. The resulting JSONObject's keys will be the strings from the names array, and the values will be the field values associated with those keys in the object. If a key is not found or not visible, then it will not be copied into the new JSONObject.
    
    Parameters:
    object - An object that has fields that should be used to make a JSONObject.
    names - An array of strings, the names of the fields to be obtained from the object.
  - JSONObject
```
public JSONObject(String source)
           throws JSONException
```
    Construct a JSONObject from a source JSON text string. This is the most commonly used JSONObject constructor.
    
    Parameters:
    source - A string beginning with { (left brace) and ending with } (right brace).
    
    Throws:
    
    JSONException - If there is a syntax error in the source string or a duplicated key.

- Method Detail
  - accumulate
```
public JSONObject accumulate(String key,
                    Object value)
                      throws JSONException
```
    Accumulate values under a key. It is similar to the put method except that if there is already an object stored under the key then a JSONArray is stored under the key to hold all of the accumulated values. If there is already a JSONArray, then the new value is appended to it. In contrast, the put method replaces the previous value. If only one value is accumulated that is not a JSONArray, then the result will be the same as using put. But if multiple values are accumulated, then the result will be like append.
    
    Parameters:
    key - A key string.
    value - An object to be accumulated under the key.
    
    Returns:
    this.
    
    Throws:
    
    JSONException - If the value is an invalid number or if the key is null.
  - append
```
public JSONObject append(String key,
                Object value)
                  throws JSONException
```
    Append values to the array under a key. If the key does not exist in the JSONObject, then the key is put in the JSONObject with its value being a JSONArray containing the value parameter. If the key was already associated with a JSONArray, then the value parameter is appended to it.
    
    Parameters:
    key - A key string.
    value - An object to be accumulated under the key.
    
    Returns:
    this.
    
    Throws:
    
    JSONException - If the key is null or if the current value associated with the key is not a JSONArray.

    Throws:
    
    JSONException - If any of the values are non-finite numbers.
  - toString
```
public String toString()
```
    Make a JSON text of this JSONObject. For compactness, no whitespace is added. If this would not result in a syntactically correct JSON text, then null will be returned instead.
    Warning: This method assumes that the data structure is acyclical.
    
    Overrides:
    
    toString in class AbstractMap
    
    Returns:
    a printable, displayable, portable, transmittable representation of the object, beginning with { (left brace) and ending with } (right brace).
  - toString
```
public String toString(int indentFactor)
                throws JSONException
```
    Make a prettyprinted JSON text of this JSONObject.
    Warning: This method assumes that the data structure is acyclical.
    
    Parameters:
    indentFactor - The number of spaces to add to each level of indentation.
    
    Returns:
    a printable, displayable, portable, transmittable representation of the object, beginning with { (left brace) and ending with } (right brace).
    
    Throws:
    
    JSONException - If the object contains an invalid number.
  - valueToString
```
public static String valueToString(Object value,
                   IJSONNode node)
                            throws JSONException
```
    Make a JSON text of an Object value. If the object has an value.toJSONString() method, then that method will be used to produce the JSON text. The method is required to produce a strictly conforming text. If the object does not contain a toJSONString method (which is the most common case), then a text will be produced by other means. If the value is an array or Collection, then a JSONArray will be made from it and its toJSONString method will be called. If the value is a MAP, then a JSONObject will be made from it and its toJSONString method will be called. Otherwise, the value's toString method will be called, and the result will be quoted.
    Warning: This method assumes that the data structure is acyclical.
    
    Parameters:
    value - The value to be serialized.
    
    Returns:
    a printable, displayable, transmittable representation of the object, beginning with { (left brace) and ending with } (right brace).
    
    Throws:
    
    JSONException - If the value is or contains an invalid number.
  - wrap
```
public static Object wrap(Object object,
          IJSONNode node)
```
    Wrap an object, if necessary. If the object is null, return the NULL object. If it is an array or collection, wrap it in a JSONArray. If it is a map, wrap it in a JSONObject. If it is a standard property (Double, String, et al) then it is already wrapped. Otherwise, if it comes from one of the java packages, turn it into a string. And if it doesn't, try to wrap it in a JSONObject. If the wrapping fails, then null is returned.
    
    Parameters:
    object - The object to wrap
    
    Returns:
    The wrapped value
  - write
```
public Writer write(Writer writer)
             throws JSONException
```
    Write the contents of the JSONObject as JSON text to a writer. For compactness, no whitespace is added.
    Warning: This method assumes that the data structure is acyclical.
    
    Returns:
    The writer.
    
    Throws:
    
    JSONException
  - isDate
```
public boolean isDate()
```
  - isImage
```
public boolean isImage()
