[OmniFaces utilities (2.0)] Encode the given Boolean/Number/CharSequence/Date 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.

Usage:

import org.omnifaces.util.Json;
import java.util.Date;
...
boolean ready = false;
int level = 25;
CharSequence cs = "hello";
Date today = new Date();
  
// output: false   
String jsonReady = Json.encode(ready);

// output: 25
String jsonLevel = Json.encode(level);

// output: "hello"
String jsonCs = Json.encode(cs);

// output: "Thu, 23 Apr 2015 11:22:58 GMT"
String jsonToday = Json.encode(today);
