[OmniFaces utilities (2.0)] Encode the given bean instance as JSON

---

[OmniFaces utilities] The encode() method encodes the given object as JSON. This supports the standard types Boolean, Number, CharSequence and Date. If the given object type does not match any of them, then it will attempt to inspect the object as a java bean whereby the public properties (with public getters) will be encoded as a JS object. It also supports Collections, Maps and arrays of them, even nested ones. The Date is formatted in RFC 1123 format, so you can if necessary just pass it straight to new Date() in JavaScript.

Encode the given Boolean/Number/CharSequence/Date as JSON

Encode the given Collection as JSON

Encode the given array as JSON

Encode the given Map as JSON

Usage:

For example, suppose we have the following bean:

import java.util.Date;

...

public class Player {

 private Boolean righthanded;

 private String name;

 private Integer age;

 private Date birthdate;

 public Player(Boolean righthanded, String name, Integer age, Date birthdate) {

  this.righthanded = righthanded;

  this.name = name;

  this.age = age;

  this.birthdate = birthdate;

 }   

 ...

 // getters and setters

}

Now we can encode a Player instance:

import org.omnifaces.util.Json;

...

String jsonPlayer = Json.encode(new Player(false, "Rafael Nadal", 28, new Date()));

JSON-encoded representation of the given object will be:

{"age":28,"birthdate":"Thu, 23 Apr 2015 13:23:47 GMT","name":"Rafael Nadal","righthanded":false}

Or, nicely formatted:

Note  Behind the scene, Json#encode() will use:

·         Json#encodeBean() - since Player is a bean

·         the supported Java standard types - since Player bean contains properties of Java standard types
