    • Method Detail

      • encode

        public static String encode​(Object object)
        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 javabean 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.
        Parameters:
        object - The object to be encoded as JSON.
        Returns:
        The JSON-encoded representation of the given object.
        Throws:
        IllegalArgumentException - When the given object or one of its properties cannot be inspected as a bean.
