Method Detail

send

public static void send(javax.servlet.http.HttpServletRequest request,
                        javax.servlet.http.HttpServletResponse response,
                        java.lang.Object o)
                 throws java.io.IOException

Answers the given request with the given object in JSON representation. This method uses the mime-type "text/html". This is the default mime type because of character set problems when using "text/javascript" in Opera.

Parameters:

request - Request

response - Response

o - Object

Throws:

java.io.IOException - if the response can't be send.

send

public static void send(javax.servlet.http.HttpServletRequest request,
                        javax.servlet.http.HttpServletResponse response,
                        java.lang.Object o,
                        java.lang.String mimeType)
                 throws java.io.IOException

Answers the given request with the given object in JSON representation.

Parameters:

request - Request

response - Response

o - Object

mimeType - mime type to use

Throws:

java.io.IOException - if the response can't be send.

dumpObjectFormatted

public static java.lang.String dumpObjectFormatted(java.lang.Object o)

Dumps the given object as formatted JSON representation. The method dumps the object to JSON first and reformats it then, so it's not the fastest method. It is mainly thought to provide debug output or similar.

Parameters:

o - Object

Returns:

JSON representation

dumpObject

public static void dumpObject(Buffer out,
                              java.lang.Object o)

Dumps the given object as JSON representation into the given buffer

Parameters:

out - buffer

o - object

forValue

public static java.lang.String forValue(java.lang.Object o)

Returns a JSON representation of the given object as String.

Parameters:

o - object

Returns:

JSON representation

forValue

public static java.lang.String forValue(java.lang.Object o,
                                        boolean formatted)

Returns a JSON representation of the given object as String.

Parameters:

o - object
