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.
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. @version 2010-03-11

This will output any object graph deeply (or null). Object references are properly handled. For example, if you had A->B, B->C, and C->A, then A will be serialized with a B object in it, B will be serialized with a C object in it, and then C will be serialized with a reference to A (ref), not a redefinition of A.

com.google.gson.stream.JsonWriter

etf.org/rfc/rfc4627.txt">RFC 4627) encoded value to a stream, one token at a time. The stream includes both literal values (strings, numbers, booleans and nulls) as well as the begin and end delimiters of objects and arrays.

Encoding JSON

To encode your data as JSON, create a new {@code JsonWriter}. Each JSON document must contain one top-level array or object. Call methods on the writer as you walk the structure's contents, nesting arrays and objects as necessary:

To write arrays, first call {@link #beginArray()}. Write each of the array's elements with the appropriate {@link #value}methods or by nesting other arrays and objects. Finally close the array using {@link #endArray()}.
To write objects, first call {@link #beginObject()}. Write each of the object's properties by alternating calls to {@link #name} with the property's value. Write property values with theappropriate {@link #value} method or by nesting other objects or arrays.Finally close the object using {@link #endObject()}.

Example

Suppose we'd like to encode a stream of messages such as the following:

  {@code [}{ "id": 912345678901, "text": "How do I stream JSON in Java?", "geo": null, "user": { "name": "json_newb", "followers_count": 41 } }, { "id": 912345678902, "text": "@json_newb just use JsonWriter!", "geo": [50.454722, -104.606667], "user": { "name": "jesse", "followers_count": 2 } } ]}

This code encodes the above structure:

    {@code}public void writeJsonStream(OutputStream out, List messages) throws IOException  JsonWriter writer = new JsonWriter(new OutputStreamWriter(out, "UTF-8")); writer.setIndentSpaces(4); writeMessagesArray(writer, messages); writer.close(); } public void writeMessagesArray(JsonWriter writer, List messages) throws IOException { writer.beginArray(); for (Message message : messages) { writeMessage(writer, message); } writer.endArray(); } public void writeMessage(JsonWriter writer, Message message) throws IOException { writer.beginObject(); writer.name("id").value(message.getId()); writer.name("text").value(message.getText()); if (message.getGeo() != null) { writer.name("geo"); writeDoublesArray(writer, message.getGeo()); } else { writer.name("geo").nullValue(); } writer.name("user"); writeUser(writer, message.getUser()); writer.endObject(); } public void writeUser(JsonWriter writer, User user) throws IOException { writer.beginObject(); writer.name("name").value(user.getName()); writer.name("followers_count").value(user.getFollowersCount()); writer.endObject(); } public void writeDoublesArray(JsonWriter writer, List doubles) throws IOException { writer.beginArray(); for (Double value : doubles) { writer.value(value); } writer.endArray(); }}

Each {@code JsonWriter} may be used to write a single JSON stream.Instances of this class are not thread safe. Calls that would result in a malformed JSON string will fail with an {@link IllegalStateException}. @author Jesse Wilson @since 1.6

javax.json.JsonWriter
A JSON writer that writes a JSON {@link JsonObject object} or{@link JsonArray array} structure to an output source.
For example, an empty JSON object can be written as follows:
```
  JsonWriter jsonWriter = new JsonWriter(...); jsonWriter.writeObject(new JsonObjectBuilder().build()); jsonWriter.close();  
```
It uses {@link javax.json.stream.JsonGenerator} internally for writing.The generator is created using one of the {@link Json}'s {@code createGenerator} methods @author Jitendra Kotamraju
org.amplafi.json.JSONWriter
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.
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.
