/**
* The object representation of a JSON document.
*
*
* JSON document examples:
*
*
*
* {}
* or
* {key : value}
* or
* {key : value, key : value, ...}
*
*
* key is a JSON string.
*
*
* value is any one of JSON object, array, number, string, true, false, null.
*
*
*
* Example of a valid JSON document:
*
*
*
* {
* "field1" : "value 1",
* "field2" : 1.234544E+26,
* "field3" : true,
* "field4" : false,
* "field5" : null,
* "field6" : {
* "inner field 1" : "inner value 1",
* "inner field 2" : 2,
* "inner field 3" : true,
* "inner field 4" : false,
* "inner field 5" : null,
* "inner field 6" : [],
* "inner field 7" : {}
* },
* "field7" : ["arr1", 3, true, false, null, [], {}]
* }
*
*
* To create {@link DbDoc} from existing string representation you could use the JsonParser.parseDoc(java.io.StringReader) method:
*
*
*
* DbDoc doc = JsonParser.parseDoc(new StringReader("{\"key1\" : \"value1\"}"));
*
*
* To construct a JSON document you can use the DbDoc, JsonString, JsonNumber, JsonArray, or JsonLiteral method. To get
* a JSON string representation use the toString() method. For example, to get the document shown above:
*
*
* DbDoc doc = new DbDocImpl().add("field1", new JsonString().setValue("value 1")).add("field2", new JsonNumber().setValue("12345.44E22"))
* .add("field3", JsonLiteral.TRUE).add("field4", JsonLiteral.FALSE).add("field5", JsonLiteral.NULL)
* .add("field6",
* new DbDocImpl().add("inner field 1", new JsonString().setValue("inner value 1")).add("inner field 2", new JsonNumber().setValue("2"))
* .add("inner field 3", JsonLiteral.TRUE).add("inner field 4", JsonLiteral.FALSE).add("inner field 5", JsonLiteral.NULL)
* .add("inner field 6", new JsonArray()).add("inner field 7", new DbDocImpl()))
* .add("field7", new JsonArray().addValue(new JsonString().setValue("arr1")).addValue(new JsonNumber().setValue("3")).addValue(JsonLiteral.TRUE)
* .addValue(JsonLiteral.FALSE).addValue(JsonLiteral.NULL).addValue(new JsonArray()).addValue(new DbDocImpl()));
*
* doc.toString();
*
