@Deprecated
public class JSONWriter
extends java.lang.Object
A JSONWriter 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 a cascade style. For example,
new JSONWriter(myWriter) .object() .key("JSON") .value("Hello, World!") .endObject();which writes
{"JSON":"Hello, World!"}
The first method called must be array
or object
.
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.
This can sometimes be easier than using a JSONObject to build a string.
