/**
|
|
||||||
* A JSONArray is an ordered sequence of values. Its external text form is a
|
|
||||||
* string wrapped in square brackets with commas separating the values. The
|
|
||||||
* internal form is an object having <code>get</code> and <code>opt</code>
|
|
||||||
* methods for accessing the values by index, and <code>put</code> methods for
|
|
||||||
* adding or replacing values. 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 object</code>.
|
|
||||||
* <p>
|
|
||||||
* The constructor can convert a JSON text into a Java object. The
|
|
||||||
* <code>toString</code> method converts to JSON text.
|
|
||||||
* <p>
|
|
||||||
* 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.
|
|
||||||
* <p>
|
|
||||||
* The texts produced by the <code>toString</code> methods strictly conform to
|
|
||||||
* 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 bracket.</li>
|
|
||||||
* <li>The <code>null</code> value will be inserted when there is <code>,</code>
|
|
||||||
* <small>(comma)</small> elision.</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>
|
|
||||||
* </ul>

|
|

* method for adding keys before values in objects. There are <code>array</code>

* <code>object</code> and <code>endObject</code> methods which make and bound
|

* {"JSON":"Hello, World!"}</pre>
|
|
||||||
* <p>
|
|
||||||
* The first method called must be <code>array</code> or <code>object</code>.
|

||||||
* There are no methods for adding commas or colons. JSONStringer adds them for
|
|
||||||
* you. Objects and arrays can be nested up to 20 levels deep.

* JSONWriter provides a quick and convenient way of producing JSON text.

* The texts produced strictly conform to JSON syntax rules. No whitespace is
|
|
||||||
* added, so the results are ready for transmission or storage. Each instance of
|
|
||||||
* JSONWriter can produce one JSON text.
|
|
||||||
* <p>
|
|
||||||
* A JSONWriter instance provides a <code>value</code> method for appending
|
|
||||||
* values to the
|
|
||||||
* text, and a <code>key</code>
|
|
||||||
* method for adding keys before values in objects. There are <code>array</code>
|
|
||||||
* and <code>endArray</code> methods that make and bound array values, and
|
|
||||||
* <code>object</code> and <code>endObject</code> methods which make and bound
|
|
||||||
* object values. All of these methods return the JSONWriter instance,
|
|
||||||
* permitting a cascade style. For example, <pre>
|
|
||||||
* new JSONWriter(myWriter)
|
|
||||||
* .object()
|
|
||||||
* .key("JSON")
|
|
||||||
* .value("Hello, World!")
|
|
||||||
* .endObject();</pre> which writes <pre>
|
|
||||||
* {"JSON":"Hello, World!"}</pre>
|
|
||||||
* <p>
|
|
||||||
* The first method called must be <code>array</code> or <code>object</code>.
|
|
||||||
* There are no methods for adding commas or colons. JSONWriter adds them for
|
|
||||||
* you. Objects and arrays can be nested up to 20 levels deep.
|
|
||||||
* <p>
|
|
||||||
* This can sometimes be easier than using a JSONObject to build a string.

* JSONzip is a binary-encoded JSON dialect. It is designed to compress the

|
|
||||||
* improve its compression. It minimizes JSON's overhead, reducing punctuation
|

* to a small number of bits. It uses Huffman encoding to reduce the average
|
|
||||||
* size of characters. It uses caches (or Keeps) to keep recently seen strings
|
|
||||||
* and values, so repetitive content (such as object keys) can be
|
|
||||||
* substantially reduced. It uses a character encoding called Kim (Keep it

* minimal) that is smaller than UTF-8 for most East European, African, and
|
|
||||||
* Asian scripts.
|
|
