public class JSONStringer extends JSONWriter
A JSONStringer instance provides a value
method for appending values to the text, and a key
method for adding keys before values in objects. There are array
and endArray
methods that make
and bound array values, and object
and endObject
methods which make and bound object values. All
of these methods return the JSONWriter instance, permitting cascade style. For example,
myString = new JSONStringer().object().key("JSON").value("Hello, World!").endObject().toString();which produces the string
{"JSON":"Hello, World!"}
The first method called must be array
or object
. 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.
This can sometimes be easier than using a JSONObject to build a string.
