public interface DbDoc extends JsonValue, Map<String,JsonValue>
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 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();
